UTF-9 and UTF-18 Efficient Transformation Formats of Unicode
|
|
Summary Publication date: Apr 2005 ISO-10646 defines a large character set called the Universal Character Set (UCS), which encompasses most of the world's writing systems. The same set of codepoints is defined by Unicode, which further defines additional character properties and other implementation details. By policy of the relevant standardization committees, changes to Unicode and amendments and additions to ISO/IEC 646 track each other, so that the character repertoires and code point assignments remain in synchronization. The current representation formats for Unicode (UTF-7, UTF-8, UTF-16) are not storage and computation efficient on platforms that utilize the 9 bit nonet as a natural storage unit instead of the 8 bit octet. This document describes a transformation format of Unicode that takes advantage of the nonet so that the format will be storage and computation efficient. |
| RFC 4043 |
Internet X.509 Public Key Infrastructure Permanent Identifier

Protocol for Carrying Authentication for Network Access (PANA) Requirements
|
|
Summary Publication date: May 2005 It is expected that future IP devices will have a variety of access technologies to gain network connectivity. Currently there are access-specific mechanisms for providing client information to the network for authentication and authorization purposes. In addition to being limited to specific access media (e.g., 802.1X for IEEE 802 links), some of these protocols are limited to specific network topologies (e.g., PPP for point-to-point links). The goal of this document is to identify the requirements for a link-layer agnostic protocol that allows a host and a network to authenticate each other for network access. This protocol will run between a client's device and an agent in the network where the agent might be a client of the AAA infrastructure. |

Summary Publication date: Jul 2005 To enable seamless IP-layer handover of a mobile node (MN) from one access router (AR) to another, the MN is required to discover the identities and capabilities of candidate ARs (CARs) for handover prior to the initiation of the handover. The act of discovery of CARs has two aspects: identifying the IP addresses of the CARs and finding their capabilities. This process is called "candidate access router discovery" (CARD). At the time of IP-layer handover, the CAR, whose capabilities are a good match to the preferences of the MN, is chosen as the target AR for handover. The protocol described in this document allows a mobile node to perform CARD. |

Context Transfer Protocol (CXTP)
|
|
Summary Publication date: Jul 2005 This document presents the Context Transfer Protocol (CXTP) that enables authorized context transfers. Context transfers allow better support for node based mobility so that the applications running on mobile nodes can operate with minimal disruption. Key objectives are to reduce latency and packet losses, and to avoid the re-initiation of signaling to and from the mobile node. |

Fast Handovers for Mobile IPv6
|
|
Summary Publication date: Jul 2005 Mobile IPv6 enables a Mobile Node to maintain its connectivity to the Internet when moving from one Access Router to another, a process referred to as handover. During handover, there is a period during which the Mobile Node is unable to send or receive packets because of link switching delay and IP protocol operations. This "handover latency" resulting from standard Mobile IPv6 procedures, namely movement detection, new Care of Address configuration, and Binding Update, is often unacceptable to real-time traffic such as Voice over IP. Reducing the handover latency could be beneficial to non-real- time, throughput-sensitive applications as well. This document specifies a protocol to improve handover latency due to Mobile IPv6 procedures. This document does not address improving the link switching latency. |

Summary Publication date: May 2005 This document describes a convention for using the Cryptographic Message Syntax (CMS) to protect a content collection. If desired, attributes can be associated with the content. |
| RFC 4074 |
Common Misbehavior Against DNS Queries for IPv6 Addresses
|
|
Summary Publication date: May 2005 There is some known misbehavior of DNS authoritative servers when they are queried for AAAA resource records. Such behavior can block IPv4 communication that should actually be available, cause a significant delay in name resolution, or even make a denial of service attack. This memo describes details of known cases and discusses their effects. |

Simple Network Time Protocol (SNTP) Configuration Option for DHCPv6
|
|
Summary Publication date: May 2005 This document describes a new DHCPv6 option for passing a list of Simple Network Time Protocol (SNTP) server addresses to a client. |
| RFC 4076 |
Renumbering Requirements for Stateless Dynamic Host Configuration Protocol for IPv6 (DHCPv6)
|
|
Summary Publication date: May 2005 IPv6 hosts using Stateless Address Autoconfiguration are able to configure their IPv6 address and default router settings automatically. However, further settings are not available. If these hosts wish to configure their DNS, NTP, or other specific settings automatically, the stateless variant of the Dynamic Host Configuration Protocol for IPv6 (DHCPv6) could be used. This combination of Stateless Address Autoconfiguration and stateless DHCPv6 could be used quite commonly in IPv6 networks. However, hosts using this combination currently have no means by which to be informed of changes in stateless DHCPv6 option settings; e.g., the addition of a new NTP server address, a change in DNS search paths, or full site renumbering. This document is presented as a problem statement from which a solution should be proposed in a subsequent document. |
| RFC 4077 |
A Negative Acknowledgement Mechanism for Signaling Compression
|
|
Summary Publication date: May 2005 This document describes a mechanism that allows Signaling Compression (SigComp) implementations to report precise error information upon receipt of a message which cannot be decompressed. This negative feedback can be used by the recipient to make fine-grained adjustments to the compressed message before retransmitting it, allowing for rapid and efficient recovery from error situations. |
| RFC 4078 |
The TV-Anytime Content Reference Identifier (CRID)
|
|
Summary Publication date: May 2005 The Uniform Resource Locator (URL) scheme "CRID:" has been devised to allow references to current or future scheduled publications of broadcast media content over television distribution platforms and the Internet. The initial intended application is as an embedded link within scheduled programme description metadata that can be used by the home user or agent to associate a programme selection with the corresponding programme location information for subsequent automatic acquisition. This document reproduces the TV-Anytime CRID definition found in the TV-Anytime content referencing specification, and is published as an RFC for ease of access and registration with the Internet Assigned Numbers Authority (IANA). |
| RFC 4079 |
A Presence Architecture for the Distribution of GEOPRIV Location Objects
|
|
Summary Publication date: Jul 2005 GEOPRIV defines the concept of a 'using protocol' -- a protocol that carries GEOPRIV location objects. GEOPRIV also defines various scenarios for the distribution of location objects that require the concepts of subscriptions and asynchronous notifications. This document examines some existing IETF work on the concept of presence, shows how presence architectures map onto GEOPRIV architectures, and moreover demonstrates that tools already developed for presence could be reused to simplify the standardization and implementation of GEOPRIV. |

Next Steps in Signaling (NSIS): Framework
|
|
Summary Publication date: Jun 2005 The Next Steps in Signaling (NSIS) working group is considering protocols for signaling information about a data flow along its path in the network. The NSIS suite of protocols is envisioned to support various signaling applications that need to install and/or manipulate such state in the network. Based on existing work on signaling requirements, this document proposes an architectural framework for these signaling protocols. This document provides a model for the network entities that take part in such signaling, and for the relationship between signaling and the rest of network operation. We decompose the overall signaling protocol suite into a generic (lower) layer, with separate upper layers for each specific signaling application. |
| RFC 4081 |
Security Threats for Next Steps in Signaling (NSIS)
|
|
Summary Publication date: Jun 2005 This threats document provides a detailed analysis of the security threats relevant to the Next Steps in Signaling (NSIS) protocol suite. It calls attention to, and helps with the understanding of, various security considerations in the NSIS Requirements, Framework, and Protocol proposals. This document does not describe vulnerabilities of specific parts of the NSIS protocol suite. |

Timed Efficient Stream Loss-Tolerant Authentication (TESLA): Multicast Source Authentication Transform Introduction
|
|
Summary Publication date: Jun 2005 This document introduces Timed Efficient Stream Loss-tolerant Authentication (TESLA). TESLA allows all receivers to check the integrity and authenticate the source of each packet in multicast or broadcast data streams. TESLA requires no trust between receivers, uses low-cost operations per packet at both sender and receiver, can tolerate any level of loss without retransmissions, and requires no per-receiver state at the sender. TESLA can protect receivers against denial of service attacks in certain circumstances. Each receiver must be loosely time-synchronized with the source in order to verify messages, but otherwise receivers do not have to send any messages. TESLA alone cannot support non-repudiation of the data source to third parties. This informational document is intended to assist in writing standardizable and secure specifications for protocols based on TESLA in different contexts. |

Input 3rd-Generation Partnership Project (3GPP) Release 5 Requirements on the Session Initiation Protocol (SIP)
|
|
Summary Publication date: May 2005 The 3rd-Generation Partnership Project (3GPP) has selected Session Initiation Protocol (SIP) as the session establishment protocol for the 3GPP IP Multimedia Core Network Subsystem (IMS). IMS is part of Release 5 of the 3GPP specifications. Although SIP is a protocol that fulfills most of the requirements for establishing a session in an IP network, SIP has never been evaluated against the specific 3GPP requirements for operation in a cellular network. In this document, we express the requirements identified by 3GPP to support SIP for Release 5 of the 3GPP IMS in cellular networks. |
| RFC 4084 |
Terminology for Describing Internet Connectivity
|
|
Summary Publication date: May 2005 As the Internet has evolved, many types of arrangements have been advertised and sold as "Internet connectivity". Because these may differ significantly in the capabilities they offer, the range of options, and the lack of any standard terminology, the effort to distinguish between these services has caused considerable consumer confusion. This document provides a list of terms and definitions that may be helpful to providers, consumers, and, potentially, regulators in clarifying the type and character of services being offered. |
| RFC 4085 |
Embedding Globally-Routable Internet Addresses Considered Harmful
|
|
Summary Publication date: Jun 2005 This document discourages the practice of embedding references to unique, globally-routable IP addresses in Internet hosts, describes some of the resulting problems, and considers selected alternatives. This document is intended to clarify best current practices in this regard. |
| RFC 4086 |
Randomness Requirements for Security
|
|
Summary Publication date: Jun 2005 Security systems are built on strong cryptographic algorithms that foil pattern analysis attempts. However, the security of these systems is dependent on generating secret quantities for passwords, cryptographic keys, and similar quantities. The use of pseudo-random processes to generate secret quantities can result in pseudo- security. A sophisticated attacker may find it easier to reproduce the environment that produced the secret quantities and to search the resulting small set of possibilities than to locate the quantities in the whole of the potential number space. Choosing random quantities to foil a resourceful and motivated adversary is surprisingly difficult. This document points out many pitfalls in using poor entropy sources or traditional pseudo-random number generation techniques for generating such quantities. It recommends the use of truly random hardware techniques and shows that the existing hardware on many systems can be used for this purpose. It provides suggestions to ameliorate the problem when a hardware solution is not available, and it gives examples of how large such quantities need to be for some applications. |
| RFC 4087 |
IP Tunnel MIB
|
|
Summary Publication date: Jun 2005 This memo defines a Management Information Base (MIB) module for use with network management protocols in the Internet community. In particular, it describes managed objects used for managing tunnels of any type over IPv4 and IPv6 networks. Extension MIB modules may be designed for managing protocol-specific objects. Likewise, extension MIB modules may be designed for managing security-specific objects. This MIB module does not support tunnels over non-IP networks. Management of such tunnels may be supported by other MIB modules. This memo obsoletes RFC 2667. |
| RFC 4088 |
Uniform Resource Identifier (URI) Scheme for the Simple Network Management Protocol (SNMP)
|
|
Summary Publication date: Jun 2005 The Simple Network Management Protocol (SNMP) and the Internet Standard Management Framework are widely used for the management of communication devices, creating a need to specify SNMP access (including access to SNMP MIB object instances) from non-SNMP management environments. For example, when out-of-band IP management is used via a separate management interface (e.g., for a device that does not support in-band IP access), a uniform way to indicate how to contact the device for management is needed. Uniform Resource Identifiers (URIs) fit this need well, as they allow a single text string to indicate a management access communication endpoint for a wide variety of IP-based protocols. This document defines a URI scheme so that SNMP can be designated as the protocol used for management. The scheme also allows a URI to designate one or more MIB object instances. |
| RFC 4089 |
IAB and IESG Recommendation for IETF Administrative Restructuring
|
|
Summary Publication date: May 2005 This document describes a joint recommendation of the Internet Architecture Board and the Internet Engineering Steering Group for administrative restructuring of the Internet Engineering Task Force. The IETF Chair declared that the IETF had consensus to follow this recommendation on November 11, 2004. Further work has been done to revise and refine the structures proposed. The recommendation is being published for the record. |

Fast Reroute Extensions to RSVP-TE for LSP Tunnels
|
|
Summary Publication date: May 2005 This document defines RSVP-TE extensions to establish backup label- switched path (LSP) tunnels for local repair of LSP tunnels. These mechanisms enable the re-direction of traffic onto backup LSP tunnels in 10s of milliseconds, in the event of a failure. Two methods are defined here. The one-to-one backup method creates detour LSPs for each protected LSP at each potential point of local repair. The facility backup method creates a bypass tunnel to protect a potential failure point; by taking advantage of MPLS label stacking, this bypass tunnel can protect a set of LSPs that have similar backup constraints. Both methods can be used to protect links and nodes during network failure. The described behavior and extensions to RSVP allow nodes to implement either method or both and to interoperate in a mixed network. |
| RFC 4091 |
The Alternative Network Address Types (ANAT) Semantics for the Session Description Protocol (SDP) Grouping Framework
|
|
Summary Publication date: Jun 2005 This document defines the Alternative Network Address Types (ANAT) semantics for the Session Description Protocol (SDP) grouping framework. The ANAT semantics allow alternative types of network addresses to establish a particular media stream. |
| RFC 4092 |
Usage of the Session Description Protocol (SDP) Alternative Network Address Types (ANAT) Semantics in the Session Initiation Protocol (SIP)
|
|
Summary Publication date: Jun 2005 This document describes how to use the Alternative Network Address Types (ANAT) semantics of the Session Description Protocol (SDP) grouping framework in SIP. In particular, we define the sdp-anat SIP option-tag. This SIP option-tag ensures that SDP session descriptions that use ANAT are only handled by SIP entities with ANAT support. To justify the need for such a SIP option-tag, we describe what could possibly happen if an ANAT-unaware SIP entity tried to handle media lines grouped with ANAT. |
| RFC 4093 |
Problem Statement: Mobile IPv4 Traversal of Virtual Private Network (VPN) Gateways
|
|
Summary Publication date: Aug 2005 Deploying Mobile-IP v4 in networks that are connected to the Internet through a Virtual Private Network (VPN) gateway presents some problems that do not currently have well-described solutions. This document aims to describe and illustrate these problems, and to propose some guidelines for possible solutions. |
| RFC 4094 |
Analysis of Existing Quality-of-Service Signaling Protocols
|
|
Summary Publication date: May 2005 This document reviews some of the existing Quality of Service (QoS) signaling protocols for an IP network. The goal here is to learn from them and to avoid common misconceptions. Further, we need to avoid mistakes during the design and implementation of any new protocol in this area. |
| RFC 4095 |
Attaching Meaning to Solicitation Class Keywords
|
|
Summary Publication date: May 2005 This document proposes a mechanism for finding a URI associated with a solicitation class keyword, which is defined in RFC 3865, the No Soliciting SMTP Service Extension. Solicitation class keywords are simple labels consisting of a domain name that has been reversed, such as "org.example.adv". These solicitation class keywords are inserted in selected header fields or used in the ESMTP service extension, including a new "No-Solicit:" header, which can contain one or more solicitation class keywords inserted by the sender. This document specifies an application based on the Dynamic Delegation Discovery System (DDDS) described in RFC 3401 and related documents. An algorithm is specified to associate a solicitation class keyword with a URI which contains further information about the meaning and usage of that solicitation class keyword. For example, the registrant of the "example.org" domain could use this mechanism to create a URI which contains detailed information about the "org.example.adv" solicitation class keyword. |
| RFC 4096 |
Policy-Mandated Labels Such as 'Adv:' in Email Subject Headers Considered Ineffective At Best
|
|
Summary Publication date: May 2005 This memo discusses policies that require certain labels to be inserted in the "Subject:" header of a mail message. Such policies are difficult to specify accurately while remaining compliant with key RFCs and are likely to be ineffective at best. This memo discusses an alternate, standards-compliant approach that is significantly simpler to specify and is somewhat less likely to be ineffective. |

Middlebox Communications (MIDCOM) Protocol Evaluation
|
|
Summary Publication date: Jun 2005 This document provides an evaluation of the applicability of SNMP (Simple Network Management Protocol), RSIP (Realm Specific Internet Protocol), Megaco, Diameter, and COPS (Common Open Policy Service) as the MIDCOM (Middlebox Communications) protocol. A summary of each of the proposed protocols against the MIDCOM requirements and the MIDCOM framework is provided. Compliancy of each of the protocols against each requirement is detailed. A conclusion summarizes how each of the protocols fares in the evaluation. |
| RFC 4098 |
Terminology for Benchmarking BGP Device Convergence in the Control Plane
|
|
Summary Publication date: Jun 2005 This document establishes terminology to standardize the description of benchmarking methodology for measuring eBGP convergence in the control plane of a single BGP device. Future documents will address iBGP convergence, the initiation of forwarding based on converged control plane information and multiple interacting BGP devices. This terminology is applicable to both IPv4 and IPv6. Illustrative examples of each version are included where relevant. |
