| RFC 3903 |
Session Initiation Protocol (SIP) Extension for Event State Publication
|
|
Summary Publication date: Oct 2004 This document describes an extension to the Session Initiation Protocol (SIP) for publishing event state used within the SIP Events framework. The first application of this extension is for the publication of presence information. The mechanism described in this document can be extended to support publication of any event state for which there exists an appropriate event package. It is not intended to be a general-purpose mechanism for transport of arbitrary data, as there are better-suited mechanisms for this purpose. |
| RFC 3904 |
Evaluation of IPv6 Transition Mechanisms for Unmanaged Networks
|
|
Summary Publication date: Sep 2004 This document analyzes issues involved in the transition of "unmanaged networks" from IPv4 to IPv6. Unmanaged networks typically correspond to home networks or small office networks. A companion paper analyzes out the requirements for mechanisms needed in various transition scenarios of these networks to IPv6. Starting from this analysis, we evaluate the suitability of mechanisms that have already been specified, proposed, or deployed. |
| RFC 3905 |
A Template for IETF Patent Disclosures and Licensing Declarations
|
|
Summary Publication date: Sep 2004 This document describes a proposal for one form of a template for IETF patent disclosures and licensing declarations. The optional use of this template is meant to simplify the process of such disclosures and licensing declarations and to assist disclosers in providing the necessary information to meet the obligations documented in RFC 3668. |

Calculating Interior Gateway Protocol (IGP) Routes Over Traffic Engineering Tunnels
|
|
Summary Publication date: Oct 2004 This document describes how conventional hop-by-hop link-state routing protocols interact with new Traffic Engineering capabilities to create Interior Gateway Protocol (IGP) shortcuts. In particular, this document describes how Dijkstra's Shortest Path First (SPF) algorithm can be adapted so that link-state IGPs will calculate IP routes to forward traffic over tunnels that are set up by Traffic Engineering. |
| RFC 3909 |
Lightweight Directory Access Protocol (LDAP) Cancel Operation
|
|
Summary Publication date: Oct 2004 This specification describes a Lightweight Directory Access Protocol (LDAP) extended operation to cancel (or abandon) an outstanding operation. Unlike the LDAP Abandon operation, but like the X.511 Directory Access Protocol (DAP) Abandon operation, this operation has a response which provides an indication of its outcome. |
| RFC 3910 |
The SPIRITS (Services in PSTN requesting Internet Services) Protocol
|
|
Summary Publication date: Oct 2004 This document describes the Services in PSTN (Public Switched Telephone Network) requesting Internet Services (SPIRITS) protocol. The purpose of the SPIRITS protocol is to support services that originate in the cellular or wireline PSTN and necessitate interactions between the PSTN and the Internet. On the PSTN side, the SPIRITS services are most often initiated from the Intelligent Network (IN) entities. Internet Call Waiting and Internet Caller-ID Delivery are examples of SPIRITS services, as are location-based services on the cellular network. The protocol defines the building blocks from which many other services can be built. |
| RFC 3911 |
The Session Initiation Protocol (SIP) 'Join' Header
|
|
Summary Publication date: Oct 2004 This document defines a new header for use with SIP multi-party applications and call control. The Join header is used to logically join an existing SIP dialog with a new SIP dialog. This primitive can be used to enable a variety of features, for example: "Barge-In", answering-machine-style "Message Screening" and "Call Center Monitoring". Note that definition of these example features is non- normative. |
| RFC 3912 |
WHOIS Protocol Specification
|
|
Summary Publication date: Sep 2004 This document updates the specification of the WHOIS protocol, thereby obsoleting RFC 954. The update is intended to remove the material from RFC 954 that does not have to do with the on-the-wire protocol, and is no longer applicable in today's Internet. This document does not attempt to change or update the protocol per se, or document other uses of the protocol that have come into existence since the publication of RFC 954. |
| RFC 3913 |
Border Gateway Multicast Protocol (BGMP): Protocol Specification
|
|
Summary Publication date: Sep 2004 This document describes the Border Gateway Multicast Protocol (BGMP), a protocol for inter-domain multicast routing. BGMP builds shared trees for active multicast groups, and optionally allows receiver domains to build source-specific, inter-domain, distribution branches where needed. BGMP natively supports "source-specific multicast" (SSM). To also support "any-source multicast" (ASM), BGMP requires that each multicast group be associated with a single root (in BGMP it is referred to as the root domain). It requires that different ranges of the multicast address space are associated (e.g., with Unicast-Prefix-Based Multicast addressing) with different domains. Each of these domains then becomes the root of the shared domain- trees for all groups in its range. Multicast participants will generally receive better multicast service if the session initiator's address allocator selects addresses from its own domain's part of the space, thereby causing the root domain to be local to at least one of the session participants. |
| RFC 3914 |
Open Pluggable Edge Services (OPES) Treatment of IAB Considerations
|
|
Summary Publication date: Oct 2004 IETF Internet Architecture Board (IAB) expressed nine architecture- level considerations for the Open Pluggable Edge Services (OPES) framework. This document describes how OPES addresses those considerations. |
| RFC 3915 |
Domain Registry Grace Period Mapping for the Extensible Provisioning Protocol (EPP)
|
|
Summary Publication date: Sep 2004 This document describes an Extensible Provisioning Protocol (EPP) extension mapping for the management of Domain Name System (DNS) domain names subject to "grace period" policies defined by the Internet Corporation for Assigned Names and Numbers (ICANN). Grace period policies exist to allow protocol actions to be reversed or otherwise revoked during a short period of time after the protocol action has been performed. Specified in XML, this mapping extends the EPP domain name mapping to provide additional features required for grace period processing. |
| RFC 3916 |
Requirements for Pseudo-Wire Emulation Edge-to-Edge (PWE3)
|
|
Summary Publication date: Sep 2004 This document describes base requirements for the Pseudo-Wire Emulation Edge to Edge Working Group (PWE3 WG). It provides guidelines for other working group documents that will define mechanisms for providing pseudo-wire emulation of Ethernet, ATM, and Frame Relay. Requirements for pseudo-wire emulation of TDM (i.e., "synchronous bit streams at rates defined by ITU G.702") are defined in another document. It should be noted that the PWE3 WG standardizes mechanisms that can be used to provide PWE3 services, but not the services themselves. |
| RFC 3917 |
Requirements for IP Flow Information Export (IPFIX)
|
|
Summary Publication date: Oct 2004 This memo defines requirements for the export of measured IP flow information out of routers, traffic measurement probes, and middleboxes. |
| RFC 3918 |
Methodology for IP Multicast Benchmarking
|
|
Summary Publication date: Oct 2004 The purpose of this document is to describe methodology specific to the benchmarking of multicast IP forwarding devices. It builds upon the tenets set forth in RFC 2544, RFC 2432 and other IETF Benchmarking Methodology Working Group (BMWG) efforts. This document seeks to extend these efforts to the multicast paradigm. The BMWG produces two major classes of documents: Benchmarking Terminology documents and Benchmarking Methodology documents. The Terminology documents present the benchmarks and other related terms. The Methodology documents define the procedures required to collect the benchmarks cited in the corresponding Terminology documents. |
| RFC 3919 |
Remote Network Monitoring (RMON) Protocol Identifiers for IPv6 and Multi Protocol Label Switching (MPLS)
|
|
Summary Publication date: Oct 2004 This memo defines additional (to those in RFC 2896) protocol identifier examples for IP version 6 and MPLS protocols. These can be used to produce valid protocolDirTable INDEX encodings, as defined by the Remote Network Monitoring MIB (Management Information Base) Version 2 [RFC 2021] and the RMON Protocol Identifier Reference [RFC 2895]. This document contains additional (to those in RFC 2896) protocol identifier macros for well-known protocols. A conformant implementation of the RMON-2 MIB [RFC 2021] can be accomplished without the use of these protocol identifiers, and accordingly, this document does not specify any IETF standard. It is published to encourage better interoperability between RMON-2 agent implementations, by providing RMON related IPv6 and MPLS protocol information. |
| RFC 3920 |
Extensible Messaging and Presence Protocol (XMPP): Core
|
|
Summary Publication date: Oct 2004 This memo defines the core features of the Extensible Messaging and Presence Protocol (XMPP), a protocol for streaming Extensible Markup Language (XML) elements in order to exchange structured information in close to real time between any two network endpoints. While XMPP provides a generalized, extensible framework for exchanging XML data, it is used mainly for the purpose of building instant messaging and presence applications that meet the requirements of RFC 2779. |
| RFC 3921 |
Extensible Messaging and Presence Protocol (XMPP): Instant Messaging and Presence
|
|
Summary Publication date: Oct 2004 This memo describes extensions to and applications of the core features of the Extensible Messaging and Presence Protocol (XMPP) that provide the basic instant messaging (IM) and presence functionality defined in RFC 2779. |

|
|
Summary Publication date: Oct 2004 This memo defines methods of end-to-end signing and object encryption for the Extensible Messaging and Presence Protocol (XMPP). |
| RFC 3924 |
Cisco Architecture for Lawful Intercept in IP Networks
|
|
Summary Publication date: Oct 2004 For the purposes of this document, lawful intercept is the lawfully authorized interception and monitoring of communications. Service providers are being asked to meet legal and regulatory requirements for the interception of voice as well as data communications in IP networks in a variety of countries worldwide. Although requirements vary from country to country, some requirements remain common even though details such as delivery formats may differ. This document describes Cisco's Architecture for supporting lawful intercept in IP networks. It provides a general solution that has a minimum set of common interfaces. This document does not attempt to address any of the specific legal requirements or obligations that may exist in a particular country. |
| RFC 3925 |
Vendor-Identifying Vendor Options for Dynamic Host Configuration Protocol version 4 (DHCPv4)
|
|
Summary Publication date: Oct 2004 The Dynamic Host Configuration Protocol (DHCP) options for Vendor Class and Vendor-Specific Information can be limiting or ambiguous when a DHCP client represents multiple vendors. This document defines two new options, modeled on the IPv6 options for vendor class and vendor-specific information, that contain Enterprise Numbers to remove ambiguity. |
| RFC 3926 |
FLUTE - File Delivery over Unidirectional Transport
|
|
Summary Publication date: Oct 2004 This document defines FLUTE, a protocol for the unidirectional delivery of files over the Internet, which is particularly suited to multicast networks. The specification builds on Asynchronous Layered Coding, the base protocol designed for massively scalable multicast distribution. |
| RFC 3927 |
Dynamic Configuration of IPv4 Link-Local Addresses
|
|
Summary Publication date: May 2005 To participate in wide-area IP networking, a host needs to be configured with IP addresses for its interfaces, either manually by the user or automatically from a source on the network such as a Dynamic Host Configuration Protocol (DHCP) server. Unfortunately, such address configuration information may not always be available. It is therefore beneficial for a host to be able to depend on a useful subset of IP networking functions even when no address configuration is available. This document describes how a host may automatically configure an interface with an IPv4 address within the 169.254/16 prefix that is valid for communication with other devices connected to the same physical (or logical) link. IPv4 Link-Local addresses are not suitable for communication with devices not directly connected to the same physical (or logical) link, and are only used where stable, routable addresses are not available (such as on ad hoc or isolated networks). This document does not recommend that IPv4 Link-Local addresses and routable addresses be configured simultaneously on the same interface. |
| RFC 3928 |
Lightweight Directory Access Protocol (LDAP) Client Update Protocol (LCUP)
|
|
Summary Publication date: Oct 2004 This document defines the Lightweight Directory Access Protocol (LDAP) Client Update Protocol (LCUP). The protocol is intended to allow an LDAP client to synchronize with the content of a directory information tree (DIT) stored by an LDAP server and to be notified about the changes to that content. |
| RFC 3929 |
Alternative Decision Making Processes for Consensus-Blocked Decisions in the IETF
|
|
Summary Publication date: Oct 2004 This document proposes an experimental set of alternative decision- making processes for use in IETF working groups. There are a small number of cases in IETF working groups in which the group has come to consensus that a particular decision must be made but cannot agree on the decision itself. This document describes alternative mechanisms for reaching a decision in those cases. This is not meant to provide an exhaustive list, but to provide a known set of tools that can be used when needed. |
| RFC 3930 |
The Protocol versus Document Points of View in Computer Protocols
|
|
Summary Publication date: Oct 2004 This document contrasts two points of view: the "document" point of view, where digital objects of interest are like pieces of paper written and viewed by people, and the "protocol" point of view where objects of interest are composite dynamic network messages. Although each point of view has a place, adherence to a document point of view can be damaging to protocol design. By understanding both points of view, conflicts between them may be clarified and reduced. |
| RFC 3931 |
Layer Two Tunneling Protocol - Version 3 (L2TPv3)
|
|
Summary Publication date: Mar 2005 This document describes "version 3" of the Layer Two Tunneling Protocol (L2TPv3). L2TPv3 defines the base control protocol and encapsulation for tunneling multiple Layer 2 connections between two IP nodes. Additional documents detail the specifics for each data link type being emulated. |
| RFC 3932 |
The IESG and RFC Editor Documents: Procedures
|
|
Summary Publication date: Oct 2004 This document describes the IESG's procedures for handling documents submitted for RFC publication via the RFC Editor, subsequent to the changes proposed by the IESG at the Seoul IETF, March 2004. This document updates procedures described in RFC 2026 and RFC 3710. |
| RFC 3933 |
A Model for IETF Process Experiments
|
|
Summary Publication date: Nov 2004 The IETF has designed process changes over the last ten years in one of two ways: announcement by the IESG, sometimes based on informal agreements with limited community involvement and awareness, and formal use of the same mechanism used for protocol specification. The first mechanism has often proven to be too lightweight, the second too heavyweight. This document specifies a middle-ground approach to the system of making changes to IETF process, one that relies heavily on a "propose and carry out an experiment, evaluate the experiment, and then establish permanent procedures based on operational experience" model rather than those previously attempted. |
| RFC 3934 |
Updates to RFC 2418 Regarding the Management of IETF Mailing Lists
|
|
Summary Publication date: Oct 2004 This document is an update to RFC 2418 that gives WG chairs explicit responsibility for managing WG mailing lists. In particular, it gives WG chairs the authority to temporarily suspend the mailing list posting privileges of disruptive individuals. |
| RFC 3935 |
A Mission Statement for the IETF
|
|
Summary Publication date: Oct 2004 This memo gives a mission statement for the IETF, tries to define the terms used in the statement sufficiently to make the mission statement understandable and useful, argues why the IETF needs a mission statement, and tries to capture some of the debate that led to this point. |
| RFC 3936 |
Procedures for Modifying the Resource reSerVation Protocol (RSVP)
|
|
Summary Publication date: Oct 2004 This memo specifies procedures for modifying the Resource reSerVation Protocol (RSVP). This memo also lays out new assignment guidelines for number spaces for RSVP messages, object classes, class-types, and sub-objects. |
| RFC 3937 |
A Uniform Resource Name (URN) Namespace for the International Press Telecommunications Council (IPTC)
|
|
Summary Publication date: Oct 2004 This document describes a URN (Uniform Resource Name) namespace for identifying persistent resources published by the International Press Telecommunications Council (IPTC). These resources include XML Data Type Definition files (DTD), XML Schema, Namespaces in XML, XSL stylesheets, other XML based document and documents of other data formats like PDF documents, Microsoft Office documents and others. |
| RFC 3938 |
Video-Message Message-Context
|
|
Summary Publication date: Oct 2004 The Message-Context header defined in RFC 3458 describes the context of a message (for example: fax-message or voice-message). This specification extends the Message-Context header with one additional context value: "video-message". A receiving user agent (UA) may use this information as a hint to optimally present the message. |
| RFC 3939 |
Calling Line Identification for Voice Mail Messages
|
|
Summary Publication date: Dec 2004 This document describes a method for identifying the originating calling party in the headers of a stored voice mail message. Two new header fields are defined for this purpose: Caller_ID and Called_Name. Caller_id is used to store sufficient information for the recipient to callback, or reply to, the sender of the message. Caller-name provides the name of the person sending the message. |
| RFC 3940 |
Negative-acknowledgment (NACK)-Oriented Reliable Multicast (NORM) Protocol
|
|
Summary Publication date: Nov 2004 This document describes the messages and procedures of the Negative- acknowledgment (NACK) Oriented Reliable Multicast (NORM) protocol. This protocol is designed to provide end-to-end reliable transport of bulk data objects or streams over generic IP multicast routing and forwarding services. NORM uses a selective, negative acknowledgment mechanism for transport reliability and offers additional protocol mechanisms to allow for operation with minimal "a priori" coordination among senders and receivers. A congestion control scheme is specified to allow the NORM protocol to fairly share available network bandwidth with other transport protocols such as Transmission Control Protocol (TCP). It is capable of operating with both reciprocal multicast routing among senders and receivers and with asymmetric connectivity (possibly a unicast return path) between the senders and receivers. The protocol offers a number of features to allow different types of applications or possibly other higher level transport protocols to utilize its service in different ways. The protocol leverages the use of FEC-based repair and other IETF reliable multicast transport (RMT) building blocks in its design. |
| RFC 3941 |
Negative-Acknowledgment (NACK)-Oriented Reliable Multicast (NORM) Building Blocks
|
|
Summary Publication date: Nov 2004 This document discusses the creation of negative-acknowledgment (NACK)-oriented reliable multicast (NORM) protocols. The rationale for NORM goals and assumptions are presented. Technical challenges for NACK-oriented (and in some cases general) reliable multicast protocol operation are identified. These goals and challenges are resolved into a set of functional "building blocks" that address different aspects of NORM protocol operation. It is anticipated that these building blocks will be useful in generating different instantiations of reliable multicast protocols. |
| RFC 3942 |
Reclassifying Dynamic Host Configuration Protocol version 4 (DHCPv4) Options
|
|
Summary Publication date: Nov 2004 This document updates RFC 2132 to reclassify Dynamic Host Configuration Protocol version 4 (DHCPv4) option codes 128 to 223 (decimal) as publicly defined options to be managed by IANA in accordance with RFC 2939. This document directs IANA to make these option codes available for assignment as publicly defined DHCP options for future options. |
| RFC 3943 |
Transport Layer Security (TLS) Protocol Compression Using Lempel-Ziv-Stac (LZS)
|
|
Summary Publication date: Nov 2004 The Transport Layer Security (TLS) protocol (RFC 2246) includes features to negotiate selection of a lossless data compression method as part of the TLS Handshake Protocol and then to apply the algorithm associated with the selected method as part of the TLS Record Protocol. TLS defines one standard compression method, which specifies that data exchanged via the record protocol will not be compressed. This document describes an additional compression method associated with the Lempel-Ziv-Stac (LZS) lossless data compression algorithm for use with TLS. This document also defines the application of the LZS algorithm to the TLS Record Protocol. |
| RFC 3944 |
H.350 Directory Services
|
|
Summary Publication date: Dec 2004 The International Telecommunications Union Standardization Sector (ITU-T) has created the H.350 series of Recommendations that specify directory services architectures in support of multimedia conferencing protocols. The goal of the architecture is to 'directory enable' multimedia conferencing so that these services can leverage existing identity management and enterprise directories. A particular goal is to enable an enterprise or service provider to maintain a canonical source of users and their multimedia conferencing systems, so that multiple call servers from multiple vendors, supporting multiple protocols, can all access the same data store. Because SIP is an IETF standard, the contents of H.350 and H.350.4 are made available via this document to the IETF community. This document contains the entire normative text of ITU-T Recommendations H.350 and H.350.4 in sections 4 and 5, respectively. The remaining sections are included only in this document, not in the ITU-T version. |
| RFC 3945 |
Generalized Multi-Protocol Label Switching (GMPLS) Architecture
|
|
Summary Publication date: Oct 2004 Future data and transmission networks will consist of elements such as routers, switches, Dense Wavelength Division Multiplexing (DWDM) systems, Add-Drop Multiplexors (ADMs), photonic cross-connects (PXCs), optical cross-connects (OXCs), etc. that will use Generalized Multi-Protocol Label Switching (GMPLS) to dynamically provision resources and to provide network survivability using protection and restoration techniques. This document describes the architecture of GMPLS. GMPLS extends MPLS to encompass time-division (e.g., SONET/SDH, PDH, G.709), wavelength (lambdas), and spatial switching (e.g., incoming port or fiber to outgoing port or fiber). The focus of GMPLS is on the control plane of these various layers since each of them can use physically diverse data or forwarding planes. The intention is to cover both the signaling and the routing part of that control plane. |
| RFC 3946 |
Generalized Multi-Protocol Label Switching (GMPLS) Extensions for Synchronous Optical Network (SONET) and Synchronous Digital Hierarchy (SDH) Control
|
|
Summary Publication date: Oct 2004 This document is a companion to the Generalized Multi-Protocol Label Switching (GMPLS) signaling. It defines the Synchronous Optical Network (SONET)/Synchronous Digital Hierarchy (SDH) technology specific information needed when using GMPLS signaling. |
| RFC 3947 |
Negotiation of NAT-Traversal in the IKE
|
|
Summary Publication date: Jan 2005 This document describes how to detect one or more network address translation devices (NATs) between IPsec hosts, and how to negotiate the use of UDP encapsulation of IPsec packets through NAT boxes in Internet Key Exchange (IKE). |
| RFC 3948 |
UDP Encapsulation of IPsec ESP Packets
|
|
Summary Publication date: Jan 2005 This protocol specification defines methods to encapsulate and decapsulate IP Encapsulating Security Payload (ESP) packets inside UDP packets for traversing Network Address Translators. ESP encapsulation, as defined in this document, can be used in both IPv4 and IPv6 scenarios. Whenever negotiated, encapsulation is used with Internet Key Exchange (IKE). |
| RFC 3949 |
File Format for Internet Fax
|
|
Summary Publication date: Feb 2005 This document is a revised version of RFC 2301. The revisions, summarized in the list attached as Annex B, are based on discussions and suggestions for improvements that have been made since RFC 2301 was issued in March 1998, and on the results of independent implementations and interoperability testing. This RFC 2301 revision describes the Tag Image File Format (TIFF) representation of image data specified by the International Telecommunication Union (ITU-T) Recommendations for black-and-white and color facsimile. This file format specification is commonly known as TIFF for Fax eXtended (TIFF-FX). It formally defines minimal, extended, and lossless Joint Bi-level Image experts Group (JBIG) profiles (Profiles S, F, J) for black-and-white fax and base JPEG, lossless JBIG, and Mixed Raster Content profiles (Profiles C, L, M) for color and grayscale fax. These profiles correspond to the content of the applicable ITU-T Recommendations. |
| RFC 3950 |
Tag Image File Format Fax eXtended (TIFF-FX) - image/tiff-fx MIME Sub-type Registration
|
|
Summary Publication date: Feb 2005 This document describes the registration of the MIME sub-type image/tiff-fx. The encodings are defined by File Format for Internet Fax and its extensions. |
| RFC 3951 |
Internet Low Bit Rate Codec (iLBC)
|
|
Summary Publication date: Dec 2004 This document specifies a speech codec suitable for robust voice communication over IP. The codec is developed by Global IP Sound (GIPS). It is designed for narrow band speech and results in a payload bit rate of 13.33 kbit/s for 30 ms frames and 15.20 kbit/s for 20 ms frames. The codec enables graceful speech quality degradation in the case of lost frames, which occurs in connection with lost or delayed IP packets. |
| RFC 3952 |
Real-time Transport Protocol (RTP) Payload Format for internet Low Bit Rate Codec (iLBC) Speech
|
|
Summary Publication date: Dec 2004 This document describes the Real-time Transport Protocol (RTP) payload format for the internet Low Bit Rate Codec (iLBC) Speech developed by Global IP Sound (GIPS). Also, within the document there are included necessary details for the use of iLBC with MIME and Session Description Protocol (SDP). |
| RFC 3953 |
Telephone Number Mapping (ENUM) Service Registration for Presence Services
|
|
Summary Publication date: Jan 2005 This document registers a Telephone Number Mapping (ENUM) service for presence. Specifically, this document focuses on provisioning pres URIs in ENUM. |
| RFC 3954 |
Cisco Systems NetFlow Services Export Version 9
|
|
Summary Publication date: Oct 2004 This document specifies the data export format for version 9 of Cisco Systems' NetFlow services, for use by implementations on the network elements and/or matching collector programs. The version 9 export format uses templates to provide access to observations of IP packet flows in a flexible and extensible manner. A template defines a collection of fields, with corresponding descriptions of structure and semantics. |
| RFC 3955 |
Evaluation of Candidate Protocols for IP Flow Information Export (IPFIX)
|
|
Summary Publication date: Oct 2004 This document contains an evaluation of the five candidate protocols for an IP Flow Information Export (IPFIX) protocol, based on the requirements document produced by the IPFIX Working Group. The protocols are characterized and grouped in broad categories, and evaluated against specific requirements. Finally, a recommendation is made to select the NetFlow v9 protocol as the basis for the IPFIX specification. |
| RFC 3956 |
Embedding the Rendezvous Point (RP) Address in an IPv6 Multicast Address
|
|
Summary Publication date: Nov 2004 This memo defines an address allocation policy in which the address of the Rendezvous Point (RP) is encoded in an IPv6 multicast group address. For Protocol Independent Multicast - Sparse Mode (PIM-SM), this can be seen as a specification of a group-to-RP mapping mechanism. This allows an easy deployment of scalable inter-domain multicast and simplifies the intra-domain multicast configuration as well. This memo updates the addressing format presented in RFC 3306. |
| RFC 3957 |
Authentication, Authorization, and Accounting (AAA) Registration Keys for Mobile IPv4
|
|
Summary Publication date: Mar 2005 Authentication, Authorization, and Accounting (AAA) servers, such as RADIUS and DIAMETER, are in use within the Internet today to provide authentication and authorization services for dial-up computers. Mobile IP for IPv4 requires strong authentication between the mobile node and its home agent. When the mobile node shares an AAA Security Association with its home AAA server, however, it is possible to use that AAA Security Association to create derived Mobility Security Associations between the mobile node and its home agent, and again between the mobile node and the foreign agent currently offering connectivity to the mobile node. This document specifies extensions to Mobile IP registration messages that can be used to create Mobility Security Associations between the mobile node and its home agent, and/or between the mobile node and a foreign agent. |
| RFC 3958 |
Domain-Based Application Service Location Using SRV RRs and the Dynamic Delegation Discovery Service (DDDS)
|
|
Summary Publication date: Jan 2005 This memo defines a generalized mechanism for application service naming that allows service location without relying on rigid domain naming conventions (so-called name hacks). The proposal defines a Dynamic Delegation Discovery System (DDDS) Application to map domain name, application service name, and application protocol dynamically to target server and port. |
| RFC 3959 |
The Early Session Disposition Type for the Session Initiation Protocol (SIP)
|
|
Summary Publication date: Dec 2004 This document defines a new disposition type (early-session) for the Content-Disposition header field in the Session Initiation Protocol (SIP). The treatment of "early-session" bodies is similar to the treatment of "session" bodies. That is, they follow the offer/answer model. Their only difference is that session descriptions whose disposition type is "early-session" are used to establish early media sessions within early dialogs, as opposed to regular sessions within regular dialogs. |
| RFC 3960 |
Early Media and Ringing Tone Generation in the Session Initiation Protocol (SIP)
|
|
Summary Publication date: Dec 2004 This document describes how to manage early media in the Session Initiation Protocol (SIP) using two models: the gateway model and the application server model. It also describes the inputs one needs to consider in defining local policies for ringing tone generation. |
| RFC 3961 |
Encryption and Checksum Specifications for Kerberos 5
|
|
Summary Publication date: Feb 2005 This document describes a framework for defining encryption and checksum mechanisms for use with the Kerberos protocol, defining an abstraction layer between the Kerberos protocol and related protocols, and the actual mechanisms themselves. The document also defines several mechanisms. Some are taken from RFC 1510, modified in form to fit this new framework and occasionally modified in content when the old specification was incorrect. New mechanisms are presented here as well. This document does NOT indicate which mechanisms may be considered "required to implement". |
| RFC 3962 |
Advanced Encryption Standard (AES) Encryption for Kerberos 5
|
|
Summary Publication date: Feb 2005 The United States National Institute of Standards and Technology (NIST) has chosen a new Advanced Encryption Standard (AES), which is significantly faster and (it is believed) more secure than the old Data Encryption Standard (DES) algorithm. This document is a specification for the addition of this algorithm to the Kerberos cryptosystem suite. |
| RFC 3963 |
Network Mobility (NEMO) Basic Support Protocol

Summary Publication date: Jan 2005 This document describes the Network Mobility (NEMO) Basic Support protocol that enables Mobile Networks to attach to different points in the Internet. The protocol is an extension of Mobile IPv6 and allows session continuity for every node in the Mobile Network as the network moves. It also allows every node in the Mobile Network to be reachable while moving around. The Mobile Router, which connects the network to the Internet, runs the NEMO Basic Support protocol with its Home Agent. The protocol is designed so that network mobility is transparent to the nodes inside the Mobile Network. |

Security Considerations for 6to4
|
|
Summary Publication date: Dec 2004 The IPv6 interim mechanism 6to4 (RFC 3056) uses automatic IPv6-over-IPv4 tunneling to interconnect IPv6 networks. The architecture includes 6to4 routers and 6to4 relay routers, which accept and decapsulate IPv4 protocol-41 ("IPv6-in-IPv4") traffic from any node in the IPv4 internet. This characteristic enables a number of security threats, mainly Denial of Service. It also makes it easier for nodes to spoof IPv6 addresses. This document discusses these issues in more detail and suggests enhancements to alleviate the problems. |

A Simple Mode of Facsimile Using Internet Mail
|
|
Summary Publication date: Dec 2004 This specification provides for "simple mode" carriage of facsimile data using Internet mail. Extensions to this document will follow. The current specification employs standard protocols and file formats such as TCP/IP, Internet mail protocols, Multipurpose Internet Mail Extensions (MIME), and Tagged Image File Format (TIFF) for Facsimile. It can send images not only to other Internet-aware facsimile devices but also to Internet-native systems, such as PCs with common email readers which can handle MIME mail and TIFF for Facsimile data. The specification facilitates communication among existing facsimile devices, Internet mail agents, and the gateways which connect them. This document is a revision of RFC 2305. There have been no technical changes. |
| RFC 3966 |
The tel URI for Telephone Numbers

| RFC 3967 |
Clarifying when Standards Track Documents may Refer Normatively to Documents at a Lower Level
|
|
Summary Publication date: Dec 2004 IETF procedures generally require that a standards track RFC may not have a normative reference to another standards track document at a lower maturity level or to a non standards track specification (other than specifications from other standards bodies). For example, a standards track document may not have a normative reference to an informational RFC. Exceptions to this rule are sometimes needed as the IETF uses informational RFCs to describe non-IETF standards or IETF-specific modes of use of such standards. This document clarifies and updates the procedure used in these circumstances. |
| RFC 3968 |
The Internet Assigned Number Authority (IANA) Header Field Parameter Registry for the Session Initiation Protocol (SIP)
|
|

| RFC 3971 |
SEcure Neighbor Discovery (SEND)
|
|
Summary Publication date: Mar 2005 IPv6 nodes use the Neighbor Discovery Protocol (NDP) to discover other nodes on the link, to determine their link-layer addresses to find routers, and to maintain reachability information about the paths to active neighbors. If not secured, NDP is vulnerable to various attacks. This document specifies security mechanisms for NDP. Unlike those in the original NDP specifications, these mechanisms do not use IPsec. |
| RFC 3972 |
Cryptographically Generated Addresses (CGA)
|
|
Summary Publication date: Mar 2005 This document describes a method for binding a public signature key to an IPv6 address in the Secure Neighbor Discovery (SEND) protocol. Cryptographically Generated Addresses (CGA) are IPv6 addresses for which the interface identifier is generated by computing a cryptographic one-way hash function from a public key and auxiliary parameters. The binding between the public key and the address can be verified by re-computing the hash value and by comparing the hash with the interface identifier. Messages sent from an IPv6 address can be protected by attaching the public key and auxiliary parameters and by signing the message with the corresponding private key. The protection works without a certification authority or any security infrastructure. |
| RFC 3973 |
Protocol Independent Multicast - Dense Mode (PIM-DM): Protocol Specification (Revised)
|
|
Summary Publication date: Jan 2005 This document specifies Protocol Independent Multicast - Dense Mode (PIM-DM). PIM-DM is a multicast routing protocol that uses the underlying unicast routing information base to flood multicast datagrams to all multicast routers. Prune messages are used to prevent future messages from propagating to routers without group membership information. |
| RFC 3974 |
SMTP Operational Experience in Mixed IPv4/v6 Environments
|
|
Summary Publication date: Jan 2005 This document discusses SMTP operational experiences in IPv4/v6 dual stack environments. As IPv6-capable SMTP servers are deployed, it has become apparent that certain configurations of MX records are necessary for stable dual-stack (IPv4 and IPv6) SMTP operation. This document clarifies the existing problems in the transition period between IPv4 SMTP and IPv6 SMTP. It also defines operational requirements for stable IPv4/v6 SMTP operation. This document does not define any new protocol. |

Interworking SIP and Intelligent Network (IN) Applications
|
|
Summary Publication date: Jan 2005 Public Switched Telephone Network (PSTN) services such as 800-number routing (freephone), time-and-day routing, credit-card calling, and virtual private network (mapping a private network number into a public number) are realized by the Intelligent Network (IN). This document addresses means to support existing IN services from Session Initiation Protocol (SIP) endpoints for an IP-host-to-phone call. The call request is originated on a SIP endpoint, but the services to the call are provided by the data and procedures resident in the PSTN/IN. To provide IN services in a transparent manner to SIP endpoints, this document describes the mechanism for interworking SIP and Intelligent Network Application Part (INAP). |
| RFC 3977 |

RTP Payload Format for H.264 Video
|
|
Summary Publication date: Feb 2005 This memo describes an RTP Payload format for the ITU-T Recommendation H.264 video codec and the technically identical ISO/IEC International Standard 14496-10 video codec. The RTP payload format allows for packetization of one or more Network Abstraction Layer Units (NALUs), produced by an H.264 video encoder, in each RTP payload. The payload format has wide applicability, as it supports applications from simple low bit-rate conversational usage, to Internet video streaming with interleaved transmission, to high bit- rate video-on-demand. |

Pseudo Wire Emulation Edge-to-Edge (PWE3) Architecture
|
|
Summary Publication date: Mar 2005 This document describes an architecture for Pseudo Wire Emulation Edge-to-Edge (PWE3). It discusses the emulation of services such as Frame Relay, ATM, Ethernet, TDM, and SONET/SDH over packet switched networks (PSNs) using IP or MPLS. It presents the architectural framework for pseudo wires (PWs), defines terminology, and specifies the various protocol elements and their functions. |
| RFC 3986 |
Uniform Resource Identifier (URI): Generic Syntax
|
|
Summary Publication date: Jan 2005 A Uniform Resource Identifier (URI) is a compact sequence of characters that identifies an abstract or physical resource. This specification defines the generic URI syntax and a process for resolving URI references that might be in relative form, along with guidelines and security considerations for the use of URIs on the Internet. The URI syntax defines a grammar that is a superset of all valid URIs, allowing an implementation to parse the common components of a URI reference without knowing the scheme-specific requirements of every possible identifier. This specification does not define a generative grammar for URIs; that task is performed by the individual specifications of each URI scheme. |
| RFC 3987 |
Internationalized Resource Identifiers (IRIs)
|
|
Summary Publication date: Jan 2005 This document defines a new protocol element, the Internationalized Resource Identifier (IRI), as a complement to the Uniform Resource Identifier (URI). An IRI is a sequence of characters from the Universal Character Set (Unicode/ISO 10646). A mapping from IRIs to URIs is defined, which means that IRIs can be used instead of URIs, where appropriate, to identify resources. The approach of defining a new protocol element was chosen instead of extending or changing the definition of URIs. This was done in order to allow a clear distinction and to avoid incompatibilities with existing software. Guidelines are provided for the use and deployment of IRIs in various protocols, formats, and software components that currently deal with URIs. |
| RFC 3988 |
Maximum Transmission Unit Signalling Extensions for the Label Distribution Protocol
|
|
Summary Publication date: Jan 2005 Proper functioning of RFC 1191 path Maximum Transmission Unit (MTU) discovery requires that IP routers have knowledge of the MTU for each link to which they are connected. As currently specified, the Label Distribution Protocol (LDP) does not have the ability to signal the MTU for a Label Switched Path (LSP) to the ingress Label Switching Router (LSR). In the absence of this functionality, the MTU for each LSP must be statically configured by network operators or by equivalent off-line mechanisms. This document specifies experimental extensions to LDP in support of LSP MTU discovery. |
| RFC 3989 |
Middlebox Communications (MIDCOM) Protocol Semantics
|
|
Summary Publication date: Feb 2005 This memo specifies semantics for a Middlebox Communication (MIDCOM) protocol to be used by MIDCOM agents for interacting with middleboxes such as firewalls and Network Address Translators (NATs). The semantics discussion does not include any specification of a concrete syntax or a transport protocol. However, a concrete protocol is expected to implement the specified semantics or, more likely, a superset of it. The MIDCOM protocol semantics is derived from the MIDCOM requirements, from the MIDCOM framework, and from working group decisions. |
| RFC 3990 |
Configuration and Provisioning for Wireless Access Points (CAPWAP) Problem Statement
|
|
Summary Publication date: Feb 2005 This document describes the Configuration and Provisioning for Wireless Access Points (CAPWAP) problem statement. |

Media Gateway Control Protocol (MGCP) Redirect and Reset Package
|
|
Summary Publication date: Feb 2005 The base Media Gateway Control Protocol (MGCP) specification (RFC 3435) allows endpoints to be redirected one endpoint at a time. This document provides extensions in the form of a new MGCP package that provides mechanisms for redirecting and resetting a group of endpoints. It also includes the ability to more accurately redirect endpoints by allowing a list of Call Agents to be specified in a preferred order. |
| RFC 3992 |
Media Gateway Control Protocol (MGCP) Lockstep State Reporting Mechanism
|
|
Summary Publication date: Feb 2005 A Media Gateway Control Protocol (MGCP) endpoint that has encountered an adverse failure condition (such as being involved in a transient call when a Call Agent failover occurred) could be left in a lockstep state whereby events are quarantined but not notified. The MGCP package described in this document provides a mechanism for reporting these situations so that the new Call Agent can take the necessary fault recovery procedures. |
| RFC 3993 |
Subscriber-ID Suboption for the Dynamic Host Configuration Protocol (DHCP) Relay Agent Option
|
|
Summary Publication date: Mar 2005 This memo defines a new Subscriber-ID suboption for the Dynamic Host Configuration Protocol's (DHCP) relay agent information option. The suboption allows a DHCP relay agent to associate a stable "Subscriber-ID" with DHCP client messages in a way that is independent of the client and of the underlying physical network infrastructure. |
| RFC 3994 |
Indication of Message Composition for Instant Messaging
|
|
Summary Publication date: Jan 2005 In instant messaging (IM) systems, it is useful to know during an IM conversation whether the other party is composing a message; e.g., typing or recording an audio message. This document defines a new status message content type and XML namespace that conveys information about a message being composed. The status message can indicate the composition of a message of any type, including text, voice, or video. The status messages are delivered to the instant messaging recipient in the same manner as the instant messages themselves. |
| RFC 3995 |
Internet Printing Protocol (IPP): Event Notifications and Subscriptions
|
|
Summary Publication date: Mar 2005 This document describes an OPTIONAL extension to the Internet Printing Protocol/1.1: Model and Semantics (RFC 2911, RFC 2910). This extension allows a client to subscribe to printing related Events. Subscriptions are modeled as Subscription Objects. The Subscription Object specifies that when one of the specified Events occurs, the Printer delivers an asynchronous Event Notification to the specified Notification Recipient via the specified Push or Pull Delivery Method (i.e., protocol). A client associates Subscription Objects with a particular Job by performing the Create-Job-Subscriptions operation or by submitting a Job with subscription information. A client associates Subscription Objects with the Printer by performing a Create-Printer-Subscriptions operation. Four other operations are defined for Subscription Objects: Get-Subscriptions-Attributes, Get-Subscriptions, Renew- Subscription, and Cancel-Subscription. |
| RFC 3996 |
Internet Printing Protocol (IPP): The 'ippget' Delivery Method for Event Notifications
|
|
Summary Publication date: Mar 2005 This document describes an extension to the Internet Printing Protocol1.1: Model and Semantics (RFC 2911, RFC 2910). This document specifies the 'ippget' Pull Delivery Method for use with the "Internet Printing Protocol (IPP): Event Notifications and Subscriptions" specification (RFC 3995). This IPPGET Delivery Method is REQUIRED for all clients and Printers that support RFC 3995. The Notification Recipient, acting as a client, fetches (pulls) Event Notifications by using the Get-Notifications operation defined in this document. |
| RFC 3997 |
