RFC 5001 DNS Name Server Identifier (NSID) Option
 
Authors:R. Austein.
Date:August 2007
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 5001
With the increased use of DNS anycast, load balancing, and other mechanisms allowing more than one DNS name server to share a singleIP address, it is sometimes difficult to tell which of a pool of name servers has answered a particular query. While existing ad-hoc mechanisms allow an operator to send follow-up queries when it is necessary to debug such a configuration, the only completely reliable way to obtain the identity of the name server that responded is to have the name server include this information in the response itself.This note defines a protocol extension to support this functionality.
 
RFC 5002 The Session Initiation Protocol (SIP) P-Profile-Key Private Header (P-Header)
 
Authors:G. Camarillo, G. Blanco.

RFC 5003 Attachment Individual Identifier (AII) Types for Aggregation
 
Authors:C. Metz, L. Martini, F. Balus, J. Sugimoto.
Date:September 2007
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 5003
The signaling protocols used to establish point-to-point pseudowires include type-length-value (TLV) fields that identify pseudowire endpoints called attachment individual identifiers (AIIs). This document defines AII structures in the form of new AII TLV fields that support AII aggregation for improved scalability and VirtualPrivate Network (VPN) auto-discovery. It is envisioned that this would be useful in large inter-domain virtual private wire service networks where pseudowires are established between selected local and remote provider edge (PE) nodes based on customer need.
 
RFC 5004 Avoid BGP Best Path Transitions from One External to Another
 
Authors:E. Chen, S. Sangli.
Date:September 2007
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 5004
In this document, we propose an extension to the BGP route selection rules that would avoid unnecessary best path transitions between external paths under certain conditions. The proposed extension would help the overall network stability, and more importantly, would eliminate certain BGP route oscillations in which more than one external path from one BGP speaker contributes to the churn.

RFC 5011 Automated Updates of DNS Security (DNSSEC) Trust Anchors
 
Authors:M. StJohns.
Date:September 2007
Formats:txt pdf
Also:STD 0074
Status:INTERNET STANDARD
DOI:10.17487/RFC 5011
This document describes a means for automated, authenticated, and authorized updating of DNSSEC "trust anchors". The method provides protection against N-1 key compromises of N keys in the trust point key set. Based on the trust established by the presence of a current anchor, other anchors may be added at the same place in the hierarchy, and, ultimately, supplant the existing anchor(s).

This mechanism will require changes to resolver management behavior(but not resolver resolution behavior), and the addition of a single flag bit to the DNSKEY record.

RFC 5014 IPv6 Socket API for Source Address Selection
 
Authors:E. Nordmark, S. Chakrabarti, J. Laganier.
Date:September 2007
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 5014
The IPv6 default address selection document (RFC 3484) describes the rules for selecting source and destination IPv6 addresses, and indicates that applications should be able to reverse the sense of some of the address selection rules through some unspecified API.However, no such socket API exists in the basic (RFC 3493) or advanced (RFC 3542) IPv6 socket API documents. This document fills that gap partially by specifying new socket-level options for source address selection and flags for the getaddrinfo() API to specify address selection based on the source address preference in accordance with the socket-level options that modify the default source address selection algorithm. The socket API described in this document will be particularly useful for IPv6 applications that want to choose between temporary and public addresses, and for Mobile IPv6 aware applications that want to use the care-of address for communication. It also specifies socket options and flags for selecting Cryptographically Generated Address (CGA) or non-CGA source addresses.
 
RFC 5015 Bidirectional Protocol Independent Multicast (BIDIR-PIM)
 
Authors:M. Handley, I. Kouvelas, T. Speakman, L. Vicisano.
Date:October 2007
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 5015
This document discusses Bidirectional PIM (BIDIR-PIM), a variant ofPIM Sparse-Mode that builds bidirectional shared trees connecting multicast sources and receivers. Bidirectional trees are built using a fail-safe Designated Forwarder (DF) election mechanism operating on each link of a multicast topology. With the assistance of the DF, multicast data is natively forwarded from sources to the Rendezvous-Point (RP) and hence along the shared tree to receivers without requiring source-specific state. The DF election takes place at RP discovery time and provides the route to the RP, thus eliminating the requirement for data-driven protocol events.

RFC 5026 Mobile IPv6 Bootstrapping in Split Scenario
 
Authors:G. Giaretta, Ed., J. Kempf, V. Devarapalli, Ed..
Date:October 2007
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 5026
A Mobile IPv6 node requires a Home Agent address, a home address, andIPsec security associations with its Home Agent before it can start utilizing Mobile IPv6 service. RFC 3775 requires that some or all of these are statically configured. This document defines how a MobileIPv6 node can bootstrap this information from non-topological information and security credentials pre-configured on the MobileNode. The solution defined in this document solves the split scenario described in the Mobile IPv6 bootstrapping problem statement in RFC 4640. The split scenario refers to the case where the MobileNode's mobility service is authorized by a different service provider than basic network access. The solution described in this document is also generically applicable to any bootstrapping case, since other scenarios are more specific realizations of the split scenario.

Examples include emergency services, directory assistance, and call-before-you-dig hot lines.
 
RFC 5032 WITHIN Search Extension to the IMAP Protocol
 
Authors:E. Burger, Ed..
Date:September 2007
Formats:txt pdf
Updates:RFC 3501
Status:PROPOSED STANDARD
DOI:10.17487/RFC 5032
This document describes the WITHIN extension to IMAP SEARCH. IMAPSEARCH returns messages whose internal date is within or outside a specified interval. The mechanism described here, OLDER and YOUNGER, differs from BEFORE and SINCE in that the client specifies an interval, rather than a date. WITHIN is useful for persistent searches where either the device does not have the capacity to perform the search at regular intervals or the network is of limited bandwidth and thus there is a desire to reduce network traffic from sending repeated requests and redundant responses.
 
RFC 5033 Specifying New Congestion Control Algorithms
 
Authors:S. Floyd, M. Allman.
Date:August 2007
Formats:txt pdf
Also:BCP 0133
Status:BEST CURRENT PRACTICE
DOI:10.17487/RFC 5033
The IETF's standard congestion control schemes have been widely shown to be inadequate for various environments (e.g., high-speed networks). Recent research has yielded many alternate congestion control schemes that significantly differ from the IETF's congestion control principles. Using these new congestion control schemes in the global Internet has possible ramifications to both the traffic using the new congestion control and to traffic using the currently standardized congestion control. Therefore, the IETF must proceed with caution when dealing with alternate congestion control proposals. The goal of this document is to provide guidance for considering alternate congestion control algorithms within the IETF.

Status:PROPOSED STANDARD
DOI:10.17487/RFC 5035
In the original Enhanced Security Services for S/MIME document (RFC2634), a structure for cryptographically linking the certificate to be used in validation with the signature was introduced; this structure was hardwired to use SHA-1. This document allows for the structure to have algorithm agility and defines a new attribute for this purpose.
 
RFC 5036 LDP Specification
 
Authors:L. Andersson, Ed., I. Minei, Ed., B. Thomas, Ed..
Date:October 2007
Formats:txt pdf
Obsoletes:RFC 3036
Updated by:RFC 6720, RFC 6790, RFC 7358, RFC 7552
Status:DRAFT STANDARD
DOI:10.17487/RFC 5036
The architecture for Multiprotocol Label Switching (MPLS) is described in RFC 3031. A fundamental concept in MPLS is that twoLabel Switching Routers (LSRs) must agree on the meaning of the labels used to forward traffic between and through them. This common understanding is achieved by using a set of procedures, called a label distribution protocol, by which one LSR informs another of label bindings it has made. This document defines a set of such procedures called LDP (for Label Distribution Protocol) by which LSRs distribute labels to support MPLS forwarding along normally routed paths.

RFC 5038 The Label Distribution Protocol (LDP) Implementation Survey Results
 
Authors:B. Thomas, L. Andersson.
Date:October 2007
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 5038
Multiprotocol Label Switching (MPLS), described in RFC 3031, is a method for forwarding packets that uses short, fixed-length values carried by packets, called labels, to determine packet next hops. A fundamental concept in MPLS is that two Label Switching Routers(LSRs) must agree on the meaning of the labels used to forward traffic between and through them. This common understanding is achieved by using a set of procedures, called a Label DistributionProtocol (as described in RFC 3036) , by which one LSR informs another of label bindings it has made. One such protocol, calledLDP, is used by LSRs to distribute labels to support MPLS forwarding along normally routed paths. This document reports on a survey ofLDP implementations conducted in August 2002 as part of the process of advancing LDP from Proposed to Draft Standard.
 
RFC 5039 The Session Initiation Protocol (SIP) and Spam
 
Authors:J. Rosenberg, C. Jennings.
Date:January 2008
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 5039
Spam, defined as the transmission of bulk unsolicited messages, has plagued Internet email. Unfortunately, spam is not limited to email.It can affect any system that enables user-to-user communications.The Session Initiation Protocol (SIP) defines a system for user-to- user multimedia communications. Therefore, it is susceptible to spam, just as email is. In this document, we analyze the problem of spam in SIP. We first identify the ways in which the problem is the same and the ways in which it is different from email. We then examine the various possible solutions that have been discussed for email and consider their applicability to SIP.

Date:October 2007
Formats:txt pdf
Updated by:RFC 6581, RFC 7146
Status:PROPOSED STANDARD
DOI:10.17487/RFC 5044
Marker PDU Aligned Framing (MPA) is designed to work as an"adaptation layer" between TCP and the Direct Data Placement protocol(DDP) as described in RFC 5041. It preserves the reliable, in-order delivery of TCP, while adding the preservation of higher-level protocol record boundaries that DDP requires. MPA is fully compliant with applicable TCP RFCs and can be utilized with existing TCP implementations. MPA also supports integrated implementations that combine TCP, MPA and DDP to reduce buffering requirements in the implementation and improve performance at the system level.

Internet Small Computer System Interface (iSCSI) Extensions forRemote Direct Memory Access (RDMA) provides the RDMA data transfer capability to iSCSI by layering iSCSI on top of an RDMA-CapableProtocol, such as the iWARP protocol suite. An RDMA-Capable Protocol provides RDMA Read and Write services, which enable data to be transferred directly into SCSI I/O Buffers without intermediate data copies. This document describes the extensions to the iSCSI protocol to support RDMA services as provided by an RDMA-Capable Protocol, such as the iWARP protocol suite.
 
RFC 5047 DA: Datamover Architecture for the Internet Small Computer System Interface (iSCSI)
 
Authors:M. Chadalapaka, J. Hufferd, J. Satran, H. Shah.

Formats:txt pdf
Updated by:RFC 7146
Status:INFORMATIONAL
DOI:10.17487/RFC 5047
The Internet Small Computer System Interface (iSCSI) is a SCSI transport protocol that maps the SCSI family of application protocols onto TCP/IP. Datamover Architecture for iSCSI (DA) defines an abstract model in which the movement of data between iSCSI end nodes is logically separated from the rest of the iSCSI protocol in order to allow iSCSI to adapt to innovations available in new IP transports. While DA defines the architectural functions required of the class of Datamover protocols, it does not define any specificDatamover protocols. Each such Datamover protocol, defined in a separate document, provides a reliable transport for all iSCSI PDUs, but actually moves the data required for certain iSCSI PDUs without involving the remote iSCSI layer itself. This document begins with an introduction of a few new abstractions, defines a layered architecture for iSCSI and Datamover protocols, and then models the interactions within an iSCSI end node between the iSCSI layer and theDatamover layer that happen in order to transparently perform remote data movement within an IP fabric. It is intended that this definition will help map iSCSI to generic Remote Direct Memory Access(RDMA)-capable IP fabrics in the future comprising TCP, the StreamControl Transmission Protocol (SCTP), and possibly other underlying network transport layers, such as InfiniBand.

Date:August 2007
Formats:txt pdf
Obsoletes:RFC 3452
Status:PROPOSED STANDARD
DOI:10.17487/RFC 5052
This document describes how to use Forward Error Correction (FEC) codes to efficiently provide and/or augment reliability for bulk data transfer over IP multicast. This document defines a framework for the definition of the information that needs to be communicated in order to use an FEC code for bulk data transfer, in addition to the encoded data itself, and for definition of formats and codes for communication of that information. Both information communicated with the encoded data itself and information that needs to be communicated 'out-of-band' are considered. The procedures for specifying new FEC codes, defining the information communication requirements associated with those codes and registering them with the Internet Assigned Numbers Authority (IANA) are also described.The requirements on Content Delivery Protocols that wish to use FEC codes defined within this framework are also defined. The companion document titled "The Use of Forward Error Correction (FEC) inReliable Multicast" describes some applications of FEC codes for delivering content. This document obsoletes RFC 3452.
 
RFC 5053 Raptor Forward Error Correction Scheme for Object Delivery
 
Authors:M. Luby, A. Shokrollahi, M. Watson, T. Stockhammer.
Date:October 2007
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 5053
This document describes a Fully-Specified Forward Error Correction(FEC) scheme, corresponding to FEC Encoding ID 1, for the Raptor forward error correction code and its application to reliable delivery of data objects.

Raptor is a fountain code, i.e., as many encoding symbols as needed can be generated by the encoder on-the-fly from the source symbols of a source block of data. The decoder is able to recover the source block from any set of encoding symbols only slightly more in number than the number of source symbols.

The Raptor code described here is a systematic code, meaning that all the source symbols are among the encoding symbols that can be generated.

Status:PROPOSED STANDARD
DOI:10.17487/RFC 5055
The Server-Based Certificate Validation Protocol (SCVP) allows a client to delegate certification path construction and certification path validation to a server. The path construction or validation(e.g., making sure that none of the certificates in the path are revoked) is performed according to a validation policy, which contains one or more trust anchors. It allows simplification of client implementations and use of a set of predefined validation policies.
 
RFC 5056 On the Use of Channel Bindings to Secure Channels
 
Authors:N. Williams.
Date:November 2007
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 5056
The concept of channel binding allows applications to establish that the two end-points of a secure channel at one network layer are the same as at a higher layer by binding authentication at the higher layer to the channel at the lower layer. This allows applications to delegate session protection to lower layers, which has various performance benefits.

This document discusses and formalizes the concept of channel binding to secure channels.

 
RFC 5057 Multiple Dialog Usages in the Session Initiation Protocol
 
Authors:R. Sparks.
Date:November 2007
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 5057
Several methods in the Session Initiation Protocol (SIP) can create an association between endpoints known as a dialog. Some of these methods can also create a different, but related, association within an existing dialog. These multiple associations, or dialog usages, require carefully coordinated processing as they have independent life-cycles, but share common dialog state. Processing multiple dialog usages correctly is not completely understood. What is understood is difficult to implement.

This memo argues that multiple dialog usages should be avoided. It discusses alternatives to their use and clarifies essential behavior for elements that cannot currently avoid them.

This is an informative document and makes no normative statements of any kind.

 
RFC 5058 Explicit Multicast (Xcast) Concepts and Options

Status:EXPERIMENTAL
DOI:10.17487/RFC 5058
While traditional IP multicast schemes (RFC 1112) are scalable for very large multicast groups, they have scalability issues with a very large number of distinct multicast groups. This document describesXcast (Explicit Multi-unicast), a new multicast scheme with complementary scaling properties: Xcast supports a very large number of small multicast sessions. Xcast achieves this by explicitly encoding the list of destinations in the data packets, instead of using a multicast group address.

This document discusses Xcast concepts and options in several areas; it does not provide a complete technical specification.

RFC 5063 Extensions to GMPLS Resource Reservation Protocol (RSVP) Graceful Restart
 
Authors:A. Satyanarayana, Ed., R. Rahman, Ed..
Date:October 2007
Formats:txt pdf
Updates:RFC 2961, RFC 3473
Status:PROPOSED STANDARD
DOI:10.17487/RFC 5063
This document describes extensions to the Resource ReservationProtocol (RSVP) Graceful Restart mechanisms defined in RFC 3473. The extensions enable the recovery of RSVP signaling state based on thePath message last sent by the node being restarted.

Previously defined Graceful Restart mechanisms, also called recovery from nodal faults, permit recovery of signaling state from adjacent nodes when the data plane has retained the associated forwarding state across a restart. Those mechanisms do not fully support signaling state recovery on ingress nodes or recovery of all RSVP objects.

The extensions defined in this document build on the RSVP Hello extensions defined in RFC 3209, and extensions for state recovery on nodal faults defined in RFC 3473. Using these extensions, the restarting node can recover all previously transmitted Path state, including the Explicit Route Object and the downstream (outgoing) interface identifiers. The extensions can also be used to recover signaling state after the restart of an ingress node.

These extensions are not used to create or restore data plane state.

The extensions optionally support the use of Summary Refresh, defined in RFC 2961, to reduce the number of messages exchanged during theRecovery Phase when the restarting node has recovered signaling state locally for one or more Label Switched Paths (LSPs).

Obsoletes:RFC 3065
Status:DRAFT STANDARD
DOI:10.17487/RFC 5065
The Border Gateway Protocol (BGP) is an inter-autonomous system routing protocol designed for Transmission Control Protocol/InternetProtocol (TCP/IP) networks. BGP requires that all BGP speakers within a single autonomous system (AS) must be fully meshed. This represents a serious scaling problem that has been well documented in a number of proposals.

This document describes an extension to BGP that may be used to create a confederation of autonomous systems that is represented as a single autonomous system to BGP peers external to the confederation, thereby removing the "full mesh" requirement. The intention of this extension is to aid in policy administration and reduce the management complexity of maintaining a large autonomous system.

This document obsoletes RFC 3065.

Email has become a popular distribution service for a variety of socially unacceptable, mass-effect purposes. The most obvious ones include spam and worms. This note recommends conventions for the operation of email submission and transport services between independent operators, such as enterprises and Internet ServiceProviders. Its goal is to improve lines of accountability for controlling abusive uses of the Internet mail service. To this end, this document offers recommendations for constructive operational policies between independent operators of email submission and transmission services.

Email authentication technologies are aimed at providing assurances and traceability between internetworked networks. In many email services, the weakest link in the chain of assurances is initial submission of a message. This document offers recommendations for constructive operational policies for this first step of email sending, the submission (or posting) of email into the transmission network. Relaying and delivery entail policies that occur subsequent to submission and are outside the scope of this document.

Time Division Multiplexing over IP (TDMoIP) is a structure-aware method for transporting Time Division Multiplexed (TDM) signals using pseudowires (PWs). Being structure-aware, TDMoIP is able to ensureTDM structure integrity, and thus withstand network degradations better than structure-agnostic transport. Structure-aware methods can distinguish individual channels, enabling packet loss concealment and bandwidth conservation. Accesibility of TDM signaling facilitates mechanisms that exploit or manipulate signaling.
 
RFC 5088 OSPF Protocol Extensions for Path Computation Element (PCE) Discovery
 
Authors:JL. Le Roux, Ed., JP. Vasseur, Ed., Y. Ikejiri, R. Zhang.
Date:January 2008
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 5088
There are various circumstances where it is highly desirable for aPath Computation Client (PCC) to be able to dynamically and automatically discover a set of Path Computation Elements (PCEs), along with information that can be used by the PCC for PCE selection.When the PCE is a Label Switching Router (LSR) participating in theInterior Gateway Protocol (IGP), or even a server participating passively in the IGP, a simple and efficient way to announce PCEs consists of using IGP flooding. For that purpose, this document defines extensions to the Open Shortest Path First (OSPF) routing protocol for the advertisement of PCE Discovery information within anOSPF area or within the entire OSPF routing domain.

RFC 5097 MIB for the UDP-Lite protocol
 
Authors:G. Renker, G. Fairhurst.
Date:January 2008
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 5097
This document specifies a Management Information Base (MIB) module for the Lightweight User Datagram Protocol (UDP-Lite). It defines a set of new MIB objects to characterise the behaviour and performance of transport layer endpoints deploying UDP-Lite. UDP-Lite resemblesUDP, but differs from the semantics of UDP by the addition of a single option. This adds the capability for variable-length data checksum coverage, which can benefit a class of applications that prefer delivery of (partially) corrupted datagram payload data in preference to discarding the datagram.
