 Definitions of Managed Objects for Circuit to Interface Translation
|
|
Summary Publication date: Jan 2002 This memo defines an extension of the Management Information Base (MIB) for use with network management protocols in TCP/IP-based internets. In particular, it defines objects for managing the insertion of interesting Circuit Interfaces into the ifTable. This is important for circuits that must be used within other MIB modules which require an ifEntry. It allows for integrated monitoring of circuits as well as routing to circuits using unaltered, pre-existing MIB modules. |
| RFC 3202 |
Definitions of Managed Objects for Frame Relay Service Level Definitions
|
|
Summary Publication date: Jan 2002 This memo defines an extension of the Management Information Base (MIB) for use with network management protocols in TCP/IP-based internets. In particular, it defines objects for managing the Frame Relay Service Level Definitions. |
| RFC 3203 |
DHCP reconfigure extension
|
|
Summary Publication date: Dec 2001 This document defines extensions to DHCP (Dynamic Host Configuration Protocol) to allow dynamic reconfiguration of a single host triggered by the DHCP server (e.g., a new IP address and/or local configuration parameters). This is achieved by introducing a unicast FORCERENEW message which forces the client to the RENEW state. The behaviour for hosts using the DHCP INFORM message to obtain configuration information is also described. |
| RFC 3204 |
MIME media types for ISUP and QSIG Objects
|
|
Summary Publication date: Dec 2001 This document describes MIME types for application/ISUP and application/QSIG objects for use in SIP applications, according to the rules defined in RFC 2048. These types can be used to identify ISUP and QSIG objects within a SIP message such as INVITE or INFO, as might be implemented when using SIP in an environment where part of the call involves interworking to the PSTN. |
| RFC 3205 |
On the use of HTTP as a Substrate
|
|
Summary Publication date: Feb 2002 Recently there has been widespread interest in using Hypertext Transfer Protocol (HTTP) as a substrate for other applications-level protocols. This document recommends technical particulars of such use, including use of default ports, URL schemes, and HTTP security mechanisms. |
| RFC 3206 |
The SYS and AUTH POP Response Codes
|
|
Summary Publication date: Feb 2002 This memo proposes two response codes: SYS and AUTH, which enable clients to unambiguously determine an optimal response to an authentication failure. In addition, a new capability (AUTH-RESP- CODE) is defined. |
| RFC 3207 |
SMTP Service Extension for Secure SMTP over Transport Layer Security
|
|
Summary Publication date: Feb 2002 This document describes an extension to the SMTP (Simple Mail Transfer Protocol) service that allows an SMTP server and client to use TLS (Transport Layer Security) to provide private, authenticated communication over the Internet. This gives SMTP agents the ability to protect some or all of their communications from eavesdroppers and attackers. |
| RFC 3208 |
PGM Reliable Transport Protocol Specification
|
|
Summary Publication date: Dec 2001 Pragmatic General Multicast (PGM) is a reliable multicast transport protocol for applications that require ordered or unordered, duplicate-free, multicast data delivery from multiple sources to multiple receivers. PGM guarantees that a receiver in the group either receives all data packets from transmissions and repairs, or is able to detect unrecoverable data packet loss. PGM is specifically intended as a workable solution for multicast applications with basic reliability requirements. Its central design goal is simplicity of operation with due regard for scalability and network efficiency. |
| RFC 3209 |
RSVP-TE: Extensions to RSVP for LSP Tunnels
|
|
Summary Publication date: Dec 2001 This document describes the use of RSVP (Resource Reservation Protocol), including all the necessary extensions, to establish label-switched paths (LSPs) in MPLS (Multi-Protocol Label Switching). Since the flow along an LSP is completely identified by the label applied at the ingress node of the path, these paths may be treated as tunnels. A key application of LSP tunnels is traffic engineering with MPLS as specified in RFC 2702. We propose several additional objects that extend RSVP, allowing the establishment of explicitly routed label switched paths using RSVP as a signaling protocol. The result is the instantiation of label- switched tunnels which can be automatically routed away from network failures, congestion, and bottlenecks. |
| RFC 3210 |
Applicability Statement for Extensions to RSVP for LSP-Tunnels
|
|
Summary Publication date: Dec 2001 This memo discusses the applicability of "Extensions to RSVP (Resource ReSerVation Protocol) for LSP Tunnels". It highlights the protocol's principles of operation and describes the network context for which it was designed. Guidelines for deployment are offered and known protocol limitations are indicated. This document is intended to accompany the submission of "Extensions to RSVP for LSP Tunnels" onto the Internet standards track. |
| RFC 3211 |
Password-based Encryption for CMS
|
|
Summary Publication date: Dec 2001 This document provides a method of encrypting data using user- supplied passwords and, by extension, any form of variable-length keying material which is not necessarily an algorithm-specific fixed-format key. The Cryptographic Message Syntax data format does not currently contain any provisions for password-based data encryption. |
| RFC 3212 |
Constraint-Based LSP Setup using LDP
|
|
Summary Publication date: Jan 2002 This document specifies mechanisms and TLVs (Type/Length/Value) for support of CR-LSPs (constraint-based routed Label Switched Path) using LDP (Label Distribution Protocol). This specification proposes an end-to-end setup mechanism of a CR-LSP initiated by the ingress LSR (Label Switching Router). We also specify mechanisms to provide means for reservation of resources using LDP. |
| RFC 3213 |
Applicability Statement for CR-LDP
|
|
Summary Publication date: Jan 2002 This document discusses the applicability of Constraint-Based LSP Setup using LDP. It discusses possible network applications, extensions to Label Distribution Protocol (LDP) required to implement constraint-based routing, guidelines for deployment and known limitations of the protocol. This document is a prerequisite to advancing CR-LDP on the standards track. |
| RFC 3214 |
LSP Modification Using CR-LDP
|
|
Summary Publication date: Jan 2002 This document presents an approach to modify the bandwidth and possibly other parameters of an established CR-LSP (Constraint-based Routed Label Switched Paths) using CR-LDP (Constraint-based Routed Label Distribution Protocol) without service interruption. After a CR-LSP is set up, its bandwidth reservation may need to be changed by the network operator, due to the new requirements for the traffic carried on that CR-LSP. The LSP modification feature can be supported by CR-LDP by use of the _modify_value for the _action indicator flag_ in the LSPID TLV. This feature has application in dynamic network resources management where traffic of different priorities and service classes is involved. |
| RFC 3215 |
LDP State Machine
|
|
Summary Publication date: Jan 2002 This document provides state machine tables for ATM (Asynchronous Transfer Mode) switch LSRs. In the current LDP specification, there is no state machine specified for processing LDP messages. We think that defining a common state machine is very important for interoperability between different LDP and CR-LDP implementations. We begin in section 1 by defining a list of terminologies. Then in section 2, we propose two sets of state machine tables for ATM switch LSRs that use downstream-on-demand mode, one method can be used for non-vc merge capable ATM LSRs, while the other one can be used for the vc-merge capable ATM LSRs. In section 3, we provides a state machine for downstream unsolicited mode ATM LSRs. We focus on the LDP state machines and the associated control blocks used for establishing and maintaining LSPs. We do not describe state machines for the "LDP controller" that is in charge of LDP session initialization, address mapping messages management, routing interface, etc. that is defined in the LDP specification. Even though the state machines in this document are specific for ATM-LSR, they can be easily adapted for other types of LSRs. |
| RFC 3216 |
SMIng Objectives
|
|
Summary Publication date: Dec 2001 This document describes the objectives for a new data definition language, suitable for the modeling of network management constructs, that can be directly mapped into SNMP and COPS-PR protocol operations. The purpose of this document is to serve as a set of objectives that a subsequent language specification should try to address. It captures the results of the working group discussions towards consensus on the SMIng objectives. |
| RFC 3217 |
Triple-DES and RC2 Key Wrapping
|
|
Summary Publication date: Dec 2001 This document specifies the algorithm for wrapping one Triple-DES key with another Triple-DES key and the algorithm for wrapping one RC2 key with another RC2 key. These key wrap algorithms were originally published in section 12.6 of RFC 2630. They are republished since these key wrap algorithms have been found to be useful in contexts beyond those supported by RFC 2630. |
| RFC 3218 |
Preventing the Million Message Attack on Cryptographic Message Syntax
|
|
Summary Publication date: Jan 2002 This memo describes a strategy for resisting the Million Message Attack. |
| RFC 3219 |
Telephony Routing over IP (TRIP)
|
|
Summary Publication date: Jan 2002 This document presents the Telephony Routing over IP (TRIP). TRIP is a policy driven inter-administrative domain protocol for advertising the reachability of telephony destinations between location servers, and for advertising attributes of the routes to those destinations. TRIP's operation is independent of any signaling protocol, hence TRIP can serve as the telephony routing protocol for any signaling protocol. The Border Gateway Protocol (BGP-4) is used to distribute routing information between administrative domains. TRIP is used to distribute telephony routing information between telephony administrative domains. The similarity between the two protocols is obvious, and hence TRIP is modeled after BGP-4. |
| RFC 3220 |
IP Mobility Support for IPv4
|
|
Summary Publication date: Jan 2002 This document specifies protocol enhancements that allow transparent routing of IP datagrams to mobile nodes in the Internet. Each mobile node is always identified by its home address, regardless of its current point of attachment to the Internet. While situated away from its home, a mobile node is also associated with a care-of address, which provides information about its current point of attachment to the Internet. The protocol provides for registering the care-of address with a home agent. The home agent sends datagrams destined for the mobile node through a tunnel to the care- of address. After arriving at the end of the tunnel, each datagram is then delivered to the mobile node. |
| RFC 3221 |
Commentary on Inter-Domain Routing in the Internet
|
|
Summary Publication date: Dec 2001 This document examines the various longer term trends visible within the characteristics of the Internet's BGP table and identifies a number of operational practices and protocol factors that contribute to these trends. The potential impacts of these practices and protocol properties on the scaling properties of the inter-domain routing space are examined. This document is the outcome of a collaborative exercise on the part of the Internet Architecture Board. |
| RFC 3222 |
Terminology for Forwarding Information Base (FIB) based Router Performance
|
|
Summary Publication date: Dec 2001 This document describes the terms to be used in a methodology that determines the IP packet forwarding performance of IP routers as a function of the forwarding information base installed within a router. The forwarding performance of an IP router may be dependent upon or may be linked to the composition and size of the forwarding information base installed within a router. |
| RFC 3224 |
Vendor Extensions for Service Location Protocol, Version 2
|
|
Summary Publication date: Jan 2002 This document specifies how the features of the Service Location Protocol, Version 2 allow for vendor extensibility safely, with no possibility of collisions. The specification introduces a new SLPv2 extension: The Vendor Opaque Extension. While proprietary protocol extensions are not encouraged by IETF standards, it is important that they not hinder interoperability of compliant implementations when they are undertaken. This document udpates RFC 2608, "The Service Location Protocol." |
| RFC 3225 |
Indicating Resolver Support of DNSSEC
|
|
Summary Publication date: Dec 2001 In order to deploy DNSSEC (Domain Name System Security Extensions) operationally, DNSSEC aware servers should only perform automatic inclusion of DNSSEC RRs when there is an explicit indication that the resolver can understand those RRs. This document proposes the use of a bit in the EDNS0 header to provide that explicit indication and describes the necessary protocol changes to implement that notification. |
| RFC 3226 |
DNSSEC and IPv6 A6 aware server/resolver message size requirements
|
|
Summary Publication date: Dec 2001 This document mandates support for EDNS0 (Extension Mechanisms for DNS) in DNS entities claiming to support either DNS Security Extensions or A6 records. This requirement is necessary because these new features increase the size of DNS messages. If EDNS0 is not supported fall back to TCP will happen, having a detrimental impact on query latency and DNS server load. This document updates RFC 2535 and RFC 2874, by adding new requirements. |
| RFC 3227 |
Guidelines for Evidence Collection and Archiving
|
|
Summary Publication date: Feb 2002 A "security incident" as defined in the "Internet Security Glossary", RFC 2828, is a security-relevant system event in which the system's security policy is disobeyed or otherwise breached. The purpose of this document is to provide System Administrators with guidelines on the collection and archiving of evidence relevant to such a security incident. If evidence collection is done correctly, it is much more useful in apprehending the attacker, and stands a much greater chance of being admissible in the event of a prosecution. |
| RFC 3228 |
IANA Considerations for IPv4 Internet Group Management Protocol (IGMP)
|
|
Summary Publication date: Feb 2002 This memo requests that the IANA create a registry for fields in the IGMP (Internet Group Management Protocol) protocol header, and provides guidance for the IANA to use in assigning parameters for those fields. |
| RFC 3229 |
Delta encoding in HTTP
|
|
Summary Publication date: Jan 2002 This document describes how delta encoding can be supported as a compatible extension to HTTP/1.1. Many HTTP (Hypertext Transport Protocol) requests cause the retrieval of slightly modified instances of resources for which the client already has a cache entry. Research has shown that such modifying updates are frequent, and that the modifications are typically much smaller than the actual entity. In such cases, HTTP would make more efficient use of network bandwidth if it could transfer a minimal description of the changes, rather than the entire new instance of the resource. This is called "delta encoding." |
| RFC 3230 |
Instance Digests in HTTP
|
|
Summary Publication date: Jan 2002 HTTP/1.1 defines a Content-MD5 header that allows a server to include a digest of the response body. However, this is specifically defined to cover the body of the actual message, not the contents of the full file (which might be quite different, if the response is a Content- Range, or uses a delta encoding). Also, the Content-MD5 is limited to one specific digest algorithm; other algorithms, such as SHA-1 (Secure Hash Standard), may be more appropriate in some circumstances. Finally, HTTP/1.1 provides no explicit mechanism by which a client may request a digest. This document proposes HTTP extensions that solve these problems. |
| RFC 3231 |
Definitions of Managed Objects for Scheduling Management Operations
|
|
Summary Publication date: Jan 2002 This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it describes a set of managed objects that are used to schedule management operations periodically or at specified dates and times. This document obsoletes RFC 2591. |
| RFC 3232 |
Assigned Numbers: RFC 1700 is Replaced by an On-line Database
|
|
Summary Publication date: Jan 2002 This memo obsoletes RFC 1700 (STD 2) "Assigned Numbers", which contained an October 1994 snapshot of assigned Internet protocol parameters. |
| RFC 3233 |
Defining the IETF
|
|
Summary Publication date: Feb 2002 This document gives a more concrete definition of "the IETF" as it understood today. Many RFCs refer to "the IETF". Many important IETF documents speak of the IETF as if it were an already-defined entity. However, no IETF document correctly defines what the IETF is. |
| RFC 3234 |
Middleboxes: Taxonomy and Issues
|
|
Summary Publication date: Feb 2002 This document is intended as part of an IETF discussion about "middleboxes" - defined as any intermediary box performing functions apart from normal, standard functions of an IP router on the data path between a source host and destination host. This document establishes a catalogue or taxonomy of middleboxes, cites previous and current IETF work concerning middleboxes, and attempts to identify some preliminary conclusions. It does not, however, claim to be definitive. |
| RFC 3235 |
Network Address Translator (NAT)-Friendly Application Design Guidelines
|
|
Summary Publication date: Jan 2002 This document discusses those things that application designers might wish to consider when designing new protocols. While many common Internet applications will operate cleanly in the presence of Network Address Translators, others suffer from a variety of problems when crossing these devices. Guidelines are presented herein to help ensure new protocols and applications will, to the extent possible, be compatible with NAT (Network Address Translation). |
| RFC 3236 |
The 'application/xhtml+xml' Media Type
|
|
Summary Publication date: Jan 2002 This document defines the 'application/xhtml+xml' MIME media type for XHTML based markup languages; it is not intended to obsolete any previous IETF documents, in particular RFC 2854 which registers 'text/html'. |
| RFC 3237 |
Requirements for Reliable Server Pooling
|
|
Summary Publication date: Jan 2002 This document defines a basic set of requirements for reliable server pooling. The goal of Reliable Server Pooling (RSerPool) is to develop an architecture and protocols for the management and operation of server pools supporting highly reliable applications, and for client access mechanisms to a server pool. |
| RFC 3238 |
IAB Architectural and Policy Considerations for Open Pluggable Edge Services
|
|
Summary Publication date: Jan 2002 This document includes comments and recommendations by the IAB on some architectural and policy issues related to the chartering of Open Pluggable Edge Services (OPES) in the IETF. OPES are services that would be deployed at application-level intermediaries in the network, for example, at a web proxy cache between the origin server and the client. These intermediaries would transform or filter content, with the explicit consent of either the content provider or the end user. |
| RFC 3239 |
Internet Printing Protocol (IPP): Requirements for Job, Printer, and Device Administrative Operations
|
|
Summary Publication date: Feb 2002 This document specifies the requirements and uses cases for some optional administrative operations for use with the Internet Printing Protocol (IPP) version 1.0 and version 1.1. Some of these administrative operations operate on the IPP Job and Printer objects. The remaining operations operate on a new Device object that more closely models a single output device. |
| RFC 3240 |
Digital Imaging and Communications in Medicine (DICOM) - Application/dicom MIME Sub-type Registration
|
|
Summary Publication date: Feb 2002 This document describes the registration of the MIME sub-type application/dicom (Digital Imaging and Communications in Medicine). The baseline encoding is defined by the DICOM Standards Committee in "Digital Imaging and Communications in Medicine". |
| RFC 3241 |
RObust Header Compression (ROHC) over PPP
|
|
Summary Publication date: Apr 2002 This document describes an option for negotiating the use of robust header compression (ROHC) on IP datagrams transmitted over the Point-to-Point Protocol (PPP). It defines extensions to the PPP Control Protocols for IPv4 and IPv6. |
| RFC 3242 |
RObust Header Compression (ROHC): A Link-Layer Assisted Profile for IP/UDP/RTP
|
|
Summary Publication date: Apr 2002 This document defines a ROHC (Robust Header Compression) profile for compression of IP/UDP/RTP (Internet Protocol/User Datagram Protocol/Real-Time Transport Protocol) packets, utilizing functionality provided by the lower layers to increase compression efficiency by completely eliminating the header for most packets during optimal operation. The profile is built as an extension to the ROHC RTP profile. It defines additional mechanisms needed in ROHC, states requirements on the assisting layer to guarantee transparency, and specifies general logic for compression and decompression making use of this header-free packet. |
| RFC 3243 |
RObust Header Compression (ROHC): Requirements and Assumptions for 0-byte IP/UDP/RTP Compression
|
|
Summary Publication date: Apr 2002 This document contains requirements for the 0-byte IP/UDP/RTP (Internet Protocol/User Datagram Protocol/Real-Time Transport Protocol) header compression scheme to be developed by the Robust Header Compression (ROHC) Working Group. It also includes the basic assumptions for the typical link layers over which 0-byte compression may be implemented, and assumptions about its usage in general. |
| RFC 3244 |
Microsoft Windows 2000 Kerberos Change Password and Set Password Protocols
|
|
Summary Publication date: Feb 2002 This memo specifies Microsoft's Windows 2000 Kerberos change password and set password protocols. The Windows 2000 Kerberos change password protocol interoperates with the original Kerberos change password protocol. Change password is a request reply protocol that includes a KRB_PRIV message that contains the new password for the user. |
| RFC 3245 |
The History and Context of Telephone Number Mapping (ENUM) Operational Decisions: Informational Documents Contributed to ITU-T Study Group 2 (SG2)
|
|
Summary Publication date: Mar 2002 RFC 2916 assigned responsibility for a number of administrative and operational details of Telephone Number Mapping (ENUM) to the IAB. It also anticipated that ITU would take responsibility for determining the legitimacy and appropriateness of applicants for delegation of "country code"-level subdomains of the top-level ENUM domain. Recently, three memos have been prepared for the ITU-T Study Group 2 (SG2) to explain the background of, and reasoning for, the relevant decisions. The IAB has also supplied a set of procedural instructions to the RIPE NCC for implementation of their part of the model. The content of the three memos is provided in this document for the information of the IETF community. |
| RFC 3246 |
An Expedited Forwarding PHB (Per-Hop Behavior)
|
|
Summary Publication date: Mar 2002 This document defines a PHB (per-hop behavior) called Expedited Forwarding (EF). The PHB is a basic building block in the Differentiated Services architecture. EF is intended to provide a building block for low delay, low jitter and low loss services by ensuring that the EF aggregate is served at a certain configured rate. This document obsoletes RFC 2598. |
| RFC 3247 |
Supplemental Information for the New Definition of the EF PHB (Expedited Forwarding Per-Hop Behavior)
|
|
Summary Publication date: Mar 2002 This document was written during the process of clarification of RFC 2598 "An Expedited Forwarding PHB" that led to the publication of revised specification of EF "An Expedited Forwarding PHB". Its primary motivation is providing additional explanation to the revised EF definition and its properties. The document also provides additional implementation examples and gives some guidance for computation of the numerical parameters of the new definition for several well known schedulers and router architectures. |
| RFC 3248 |
A Delay Bound alternative revision of RFC 2598
|
|
Summary Publication date: Mar 2002 For historical interest, this document captures the EF Design Team's proposed solution, preferred by the original authors of RFC 2598 but not adopted by the working group in December 2000. The original definition of EF was based on comparison of forwarding on an unloaded network. This experimental Delay Bound (DB) PHB requires a bound on the delay of packets due to other traffic in the network. At the Pittsburgh IETF meeting in August 2000, the Differentiated Services working group faced serious questions regarding RFC 2598 - the group's standards track definition of the Expedited Forwarding (EF) Per Hop Behavior (PHB). An 'EF Design Team' volunteered to develop a re-expression of RFC 2598, bearing in mind the issues raised in the DiffServ group. At the San Diego IETF meeting in December 2000 the DiffServ working group decided to pursue an alternative re-expression of the EF PHB. |
| RFC 3249 |
Implementers Guide for Facsimile Using Internet Mail
|
|
Summary Publication date: Sep 2002 This document is intended for the implementers of software that use email to send to facsimiles using RFC 2305 and 2532. This is an informational document and its guidelines do not supersede the referenced documents. |
| RFC 3250 |
Tag Image File Format Fax eXtended (TIFF-FX) - image/tiff-fx MIME Sub-type Registration
|
|
Summary Publication date: Sep 2002 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 3251 |
Electricity over IP
|
|
Summary Publication date: Apr 2002 Mostly Pointless Lamp Switching (MPLampS) is an architecture for carrying electricity over IP (with an MPLS control plane). According to our marketing department, MPLampS has the potential to dramatically lower the price, ease the distribution and usage, and improve the manageability of delivering electricity. This document is motivated by such work as SONET/SDH over IP/MPLS (with apologies to the authors). Readers of the previous work have been observed scratching their heads and muttering, "What next?". This document answers that question. This document has also been written as a public service. The "Sub- IP" area has been formed to give equal opportunity to those working on technologies outside of traditional IP networking to write complicated IETF documents. There are possibly many who are wondering how to exploit this opportunity and attain high visibility. Towards this goal, we see the topics of "foo-over-MPLS" (or MPLS control for random technologies) as highly amenable for producing a countless number of unimplementable documents. This document illustrates the key ingredients that go into producing any "foo- over-MPLS" document and may be used as a template for all such work. |
| RFC 3252 |
Binary Lexical Octet Ad-hoc Transport
|
|
Summary Publication date: Apr 2002 This document defines a reformulation of IP and two transport layer protocols (TCP and UDP) as XML applications. |
| RFC 3253 |
Versioning Extensions to WebDAV (Web Distributed Authoring and Versioning)
|
|
Summary Publication date: Mar 2002 This document specifies a set of methods, headers, and resource types that define the WebDAV (Web Distributed Authoring and Versioning) versioning extensions to the HTTP/1.1 protocol. WebDAV versioning will minimize the complexity of clients that are capable of interoperating with a variety of versioning repository managers, to facilitate widespread deployment of applications capable of utilizing the WebDAV Versioning services. WebDAV versioning includes automatic versioning for versioning-unaware clients, version history management, workspace management, baseline management, activity management, and URL namespace versioning. |
| RFC 3254 |
Definitions for talking about directories
|
|
Summary Publication date: Apr 2002 When discussing systems for making information accessible through the Internet in standardized ways, it may be useful if the people who are discussing it have a common understanding of the terms they use. For example, a reference to this document would give one the power to agree that the DNS (Domain Name System) is a global lookup repository with perimeter integrity and loose, converging consistency. On the other hand, a LDAP (Lightweight Directory Access Protocol) directory server is a local, centralized repository with both lookup and search capability. This document discusses one group of such systems which is known under the term, "directories". |
| RFC 3255 |
Extending Point-to-Point Protocol (PPP) over Synchronous Optical NETwork/Synchronous Digital Hierarchy (SONET/SDH) with virtual concatenation, high order and low order payloads
|
|
Summary Publication date: Apr 2002 This document describes an extension to the mapping of Point-to-Point Protocol (PPP) into Synchronous Optical NETwork/Synchronous Digital Hierarchy (SONET/SDH) to include the use of SONET/SDH SPE/VC virtual concatenation and the use of both high order and low order payloads. |
| RFC 3256 |
The DOCSIS (Data-Over-Cable Service Interface Specifications) Device Class DHCP (Dynamic Host Configuration Protocol) Relay Agent Information Sub-option
|
|
Summary Publication date: Apr 2002 This document proposes a new sub-option to the DHCP (Dynamic Host Configuration Protocol) Relay Agent Information Option. This new sub-option is for use with DOCSIS (Data-Over-Cable Service Interface Specifications) cable modems and describes a "device class" to which the cable modem belongs. The cable modem signals its device class information to the Relay Agent using DOCSIS signaling, and the Relay Agent forwards the device class information to the DHCP Server which can then make a policy decision based on it. |
| RFC 3257 |
Stream Control Transmission Protocol Applicability Statement
|
|
Summary Publication date: Apr 2002 This document describes the applicability of the Stream Control Transmission Protocol (SCTP). It also contrasts SCTP with the two dominant transport protocols, User Datagram Protocol (UDP) & Transmission Control Protocol (TCP), and gives some guidelines for when best to use SCTP and when not best to use SCTP. |
| RFC 3258 |
Distributing Authoritative Name Servers via Shared Unicast Addresses
|
|
Summary Publication date: Apr 2002 This memo describes a set of practices intended to enable an authoritative name server operator to provide access to a single named server in multiple locations. The primary motivation for the development and deployment of these practices is to increase the distribution of Domain Name System (DNS) servers to previously under-served areas of the network topology and to reduce the latency for DNS query responses in those areas. |
| RFC 3259 |
A Message Bus for Local Coordination
|
|
Summary Publication date: Apr 2002 The local Message Bus (Mbus) is a light-weight message-oriented coordination protocol for group communication between application components. The Mbus provides automatic location of communication peers, subject based addressing, reliable message transfer and different types of communication schemes. The protocol is layered on top of IP multicast and is specified for IPv4 and IPv6. The IP multicast scope is limited to link-local multicast. This document specifies the Mbus protocol, i.e., message syntax, addressing and transport mechanisms. |
| RFC 3260 |
New Terminology and Clarifications for Diffserv
|
|
Summary Publication date: Apr 2002 This memo captures Diffserv working group agreements concerning new and improved terminology, and provides minor technical clarifications. It is intended to update RFC 2474, RFC 2475 and RFC 2597. When RFCs 2474 and 2597 advance on the standards track, and RFC 2475 is updated, it is intended that the revisions in this memo will be incorporated, and that this memo will be obsoleted by the new RFCs. |
| RFC 3261 |
SIP: Session Initiation Protocol
|
|
Summary Publication date: Jun 2002 This document describes Session Initiation Protocol (SIP), an application-layer control (signaling) protocol for creating, modifying, and terminating sessions with one or more participants. These sessions include Internet telephone calls, multimedia distribution, and multimedia conferences. SIP invitations used to create sessions carry session descriptions that allow participants to agree on a set of compatible media types. SIP makes use of elements called proxy servers to help route requests to the user's current location, authenticate and authorize users for services, implement provider call-routing policies, and provide features to users. SIP also provides a registration function that allows users to upload their current locations for use by proxy servers. SIP runs on top of several different transport protocols. |
| RFC 3262 |
Reliability of Provisional Responses in Session Initiation Protocol (SIP)
|
|
Summary Publication date: Jun 2002 This document specifies an extension to the Session Initiation Protocol (SIP) providing reliable provisional response messages. This extension uses the option tag 100rel and defines the Provisional Response ACKnowledgement (PRACK) method. |
| RFC 3263 |
Session Initiation Protocol (SIP): Locating SIP Servers

Compressed Data Content Type for Cryptographic Message Syntax (CMS)
|
|
Summary Publication date: Jun 2002 This document defines a format for using compressed data as a Cryptographic Message Syntax (CMS) content type. Compressing data before transmission provides a number of advantages, including the elimination of data redundancy which could help an attacker, speeding up processing by reducing the amount of data to be processed by later steps (such as signing or encryption), and reducing overall message size. Although there have been proposals for adding compression at other levels (for example at the MIME or SSL level), these don't address the problem of compression of CMS content unless the compression is supplied by an external means (for example by intermixing MIME and CMS). |

Service in the Public Switched Telephone Network/Intelligent Network (PSTN/IN) Requesting InTernet Service (SPIRITS) Protocol Requirements
|
|
Summary Publication date: Aug 2002 This document describes the SPIRITS protocol requirements, based on the architecture presented in RFC 3136. (SPIRITS stands for "Service in the PSTN/IN Requesting InTernet Service".) The purpose of the protocol is to support services that originate in the Public Switched Telephone Network (PSTN) and necessitate the interactions between the PSTN and the Internet. Similarly, such services are called SPIRITS services. (Internet Call Waiting, Internet Caller-ID Delivery, and Internet Call Forwarding are examples of SPIRIT services, but the protocol is to define the building blocks from which many other services can be built.) On the PSTN side, the SPIRITS services are initiated from the Intelligent Network (IN) entities; the earlier IETF work on the PSTN/Internet Interworking (PINT) resulted in the protocol (RFC 2848) in support of the services initiated the other way around--from the Internet to PSTN. To this end, this document lists general requirements for the SPIRITS protocol as well as those pertinent to IN, Wireless IN, and PINT building blocks. The document also presents the SPIRITS WG consensus on the choice of the SPIRITS signaling protocol. |
