RFC 4042 UTF-9 and UTF-18 Efficient Transformation Formats of Unicode
 
Authors:M. Crispin.
Date:April 2005
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 4042
ISO-10646 defines a large character set called the UniversalCharacter 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 toISO/IEC 10646 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.

Status:INFORMATIONAL
DOI:10.17487/RFC 4054
Optical networking poses a number challenges for Generalized Multi-Protocol Label Switching (GMPLS). Fundamentally, optical technology is an analog rather than digital technology whereby the optical layer is lowest in the transport hierarchy and hence has an intimate relationship with the physical geography of the network. This contribution surveys some of the aspects of optical networks that impact routing and identifies possible GMPLS responses for each: (1)Constraints arising from the design of new software controllable network elements, (2) Constraints in a single all-optical domain without wavelength conversion, (3) Complications arising in more complex networks incorporating both all-optical and opaque architectures, and (4) Impacts of diversity constraints.

Status:INFORMATIONAL
DOI:10.17487/RFC 4058
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 theAAA infrastructure.

Formats:txt pdf
Status:EXPERIMENTAL
DOI:10.17487/RFC 4066
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 ofCARs 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.

RFC 4068 Fast Handovers for Mobile IPv6

Date:July 2005
Formats:txt pdf
Obsoleted by:RFC 5268
Status:EXPERIMENTAL
DOI:10.17487/RFC 4068
Mobile IPv6 enables a Mobile Node to maintain its connectivity to theInternet 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 BindingUpdate, is often unacceptable to real-time traffic such as Voice overIP. 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.

DOI:10.17487/RFC 4076
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 HostConfiguration Protocol for IPv6 (DHCPv6) could be used. This combination of Stateless Address Autoconfiguration and statelessDHCPv6 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.

Date:June 2005
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 4082
This document introduces Timed Efficient Stream Loss-tolerantAuthentication (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.

DOI:10.17487/RFC 4086
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.

Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 4088
The Simple Network Management Protocol (SNMP) and the InternetStandard 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 ResourceIdentifiers (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 4090 Fast Reroute Extensions to RSVP-TE for LSP Tunnels
 
Authors:P. Pan, Ed., G. Swallow, Ed., A. Atlas, Ed..
Date:May 2005
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 4090
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
 
Authors:G. Camarillo, J. Rosenberg.
Date:June 2005
Formats:txt pdf
Obsoleted by:RFC 5245
Status:PROPOSED STANDARD
DOI:10.17487/RFC 4091
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)
 
Authors:G. Camarillo, J. Rosenberg.
Date:June 2005
Formats:txt pdf
Obsoleted by:RFC 5245
Status:PROPOSED STANDARD
DOI:10.17487/RFC 4092
This document describes how to use the Alternative Network AddressTypes (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
 
Authors:F. Adrangi, Ed., H. Levkowetz, Ed..
Date:August 2005
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 4093
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
 
Authors:J. Manner, X. Fu.
Date:May 2005
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 4094
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
 
Authors:C. Malamud.
Date:May 2005
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 4095
This document proposes a mechanism for finding a URI associated with a solicitation class keyword, which is defined in RFC 3865, the NoSoliciting 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 DynamicDelegation 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
 
Authors:C. Malamud.
Date:May 2005
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 4096
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.
 
RFC 4097 Middlebox Communications (MIDCOM) Protocol Evaluation
 
Authors:M. Barnes, Ed..
Date:June 2005
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 4097
This document provides an evaluation of the applicability of SNMP(Simple Network Management Protocol), RSIP (Realm Specific InternetProtocol), 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
 
Authors:H. Berkowitz, E. Davies, Ed., S. Hares, P. Krishnaswamy, M. Lepp.
Date:June 2005
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 4098
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.
