RFC Abstracts
RFC5041 - Direct Data Placement over Reliable Transports
The Direct Data Placement protocol provides information to Place the incoming data directly into an upper layer protocol's receive buffer without intermediate buffers. This removes excess CPU and memory utilization associated with transferring data through the intermediate buffers. [STANDARDS-TRACK]
RFC5040 - A Remote Direct Memory Access Protocol Specification
This document defines a Remote Direct Memory Access Protocol (RDMAP) that operates over the Direct Data Placement Protocol (DDP protocol). RDMAP provides read and write services directly to applications and enables data to be transferred directly into Upper Layer Protocol (ULP) Buffers without intermediate data copies. It also enables a kernel bypass implementation. [STANDARDS-TRACK]
RFC5039 - The Session Initiation Protocol (SIP) and Spam
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. This memo provides information for the Internet community.
RFC5038 - The Label Distribution Protocol (LDP) Implementation Survey Results
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 Distribution Protocol (as described in RFC 3036) , by which one LSR informs another of label bindings it has made. One such protocol, called LDP, is used by LSRs to distribute labels to support MPLS forwarding along normally routed paths. This document reports on a survey of LDP implementations conducted in August 2002 as part of the process of advancing LDP from Proposed to Draft Standard. This memo provides information for the Internet community.
RFC5037 - Experience with the Label Distribution Protocol (LDP)
The purpose of this memo is to document how some of the requirements specified in RFC 1264 for advancing protocols developed by working groups within the IETF Routing Area to Draft Standard have been satisfied by LDP (Label Distribution Protocol). Specifically, this report documents operational experience with LDP, requirement 5 of section 5.0 in RFC 1264. This memo provides information for the Internet community.
RFC5036 - LDP Specification
The architecture for Multiprotocol Label Switching (MPLS) is described in RFC 3031. 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 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. [STANDARDS-TRACK]
RFC5035 - Enhanced Security Services (ESS) Update: Adding CertID Algorithm Agility
In the original Enhanced Security Services for S/MIME document (RFC 2634), 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. [STANDARDS-TRACK]
RFC5034 - The Post Office Protocol (POP3) Simple Authentication and Security Layer (SASL) Authentication Mechanism
This document defines a profile of the Simple Authentication and Security Layer (SASL) for the Post Office Protocol (POP3). This extension allows a POP3 client to indicate an authentication mechanism to the server, perform an authentication protocol exchange, and optionally negotiate a security layer for subsequent protocol interactions during this session.
RFC5033 - Specifying New Congestion Control Algorithms
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. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.
RFC5032 - WITHIN Search Extension to the IMAP Protocol
This document describes the WITHIN extension to IMAP SEARCH. IMAP SEARCH 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. [STANDARDS-TRACK]
RFC5031 - A Uniform Resource Name (URN) for Emergency and Other Well-Known Services
The content of many communication services depends on the context, such as the user's location. We describe a 'service' URN that allows well-known context-dependent services that can be resolved in a distributed manner to be identified. Examples include emergency services, directory assistance, and call-before-you-dig hot lines. [STANDARDS-TRACK]
RFC5030 - Mobile IPv4 RADIUS Requirements

RFC5026 - Mobile IPv6 Bootstrapping in Split Scenario
A Mobile IPv6 node requires a Home Agent address, a home address, and IPsec 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 Mobile IPv6 node can bootstrap this information from non-topological information and security credentials pre-configured on the Mobile Node. 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 Mobile Node'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. [STANDARDS-TRACK]
RFC5025 - Presence Authorization Rules
Authorization is a key function in presence systems. Authorization policies, also known as authorization rules, specify what presence information can be given to which watchers, and when. This specification defines an Extensible Markup Language (XML) document format for expressing presence authorization rules. Such a document can be manipulated by clients using the XML Configuration Access Protocol (XCAP), although other techniques are permitted. [STANDARDS-TRACK]

RFC5016 - Requirements for a DomainKeys Identified Mail (DKIM) Signing Practices Protocol
DomainKeys Identified Mail (DKIM) provides a cryptographic mechanism for domains to assert responsibility for the messages they handle. A related mechanism will allow an administrator to publish various statements about their DKIM signing practices. This document defines requirements for this mechanism, distinguishing between those that must be satisfied (MUST), and those that are highly desirable (SHOULD). This memo provides information for the Internet community.
RFC5015 - Bidirectional Protocol Independent Multicast (BIDIR-PIM)
This document discusses Bidirectional PIM (BIDIR-PIM), a variant of PIM 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. [STANDARDS-TRACK]
RFC5014 - IPv6 Socket API for Source Address Selection
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. This memo provides information for the Internet community.
RFC5013 - The Dublin Core Metadata Element Set
This document defines fifteen metadata elements for resource description in a cross-disciplinary information environment. This memo provides information for the Internet community.

This memo provides information for the Internet community.
RFC5011 - Automated Updates of DNS Security (DNSSEC) Trust Anchors
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).
RFC5010 - The Dynamic Host Configuration Protocol Version 4 (DHCPv4) Relay Agent Flags Suboption
This memo defines a new suboption of the Dynamic Host Configuration Protocol (DHCP) relay agent information option that allows the DHCP relay to specify flags for the forwarded packet. One flag is defined to indicate whether the DHCP relay received the packet via a unicast or broadcast packet. This information may be used by the DHCP server to better serve clients based on whether their request was originally broadcast or unicast. [STANDARDS-TRACK]
RFC5009 - Private Header (P-Header) Extension to the Session Initiation Protocol (SIP) for Authorization of Early Media

RFC5005 - Feed Paging and Archiving
This specification defines three types of syndicated Web feeds that enable publication of entries across one or more feed documents. This includes "paged" feeds for piecemeal access, "archived" feeds that allow reconstruction of the feed's contents, and feeds that are explicitly "complete". [STANDARDS-TRACK]
RFC5004 - Avoid BGP Best Path Transitions from One External to Another
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. [STANDARDS-TRACK]
RFC5003 - Attachment Individual Identifier (AII) Types for Aggregation
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 Virtual Private 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. [STANDARDS-TRACK]
RFC5002 - The Session Initiation Protocol (SIP) P-Profile-Key Private Header (P-Header)
This document specifies the SIP P-Profile-Key P-header. This header field is used in the 3rd-Generation Partnership Project (3GPP) IMS (IP Multimedia Subsystem) to provide SIP registrars and SIP proxy servers with the key of the profile corresponding to the destination SIP URI of a particular SIP request. This memo provides information for the Internet community.
RFC5001 - DNS Name Server Identifier (NSID) Option
With the increased use of DNS anycast, load balancing, and other mechanisms allowing more than one DNS name server to share a single IP 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. [STANDARDS-TRACK]
RFC5000 - Internet Official Protocol Standards
This document is published by the RFC Editor to provide a summary of the current standards protocols (as of 18 February 2008).

RFC5011 - Automated Updates of DNS Security (DNSSEC) Trust Anchors
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).
RFC5010 - The Dynamic Host Configuration Protocol Version 4 (DHCPv4) Relay Agent Flags Suboption
This memo defines a new suboption of the Dynamic Host Configuration Protocol (DHCP) relay agent information option that allows the DHCP relay to specify flags for the forwarded packet. One flag is defined to indicate whether the DHCP relay received the packet via a unicast or broadcast packet. This information may be used by the DHCP server to better serve clients based on whether their request was originally broadcast or unicast. [STANDARDS-TRACK]
RFC5009 - Private Header (P-Header) Extension to the Session Initiation Protocol (SIP) for Authorization of Early Media
This document describes a private Session Initiation Protocol (SIP) header field (P-header) to be used by the European Telecommunications Standards Institute (ETSI) Telecommunications and Internet-converged Services and Protocols for Advanced Networks (TISPAN) for the purpose of authorizing early media flows in Third Generation Partnership Project (3GPP) IP Multimedia Subsystems (IMS). This header field is useful in any SIP network that is interconnected with other SIP networks and needs to control the flow of media in the early dialog state. This memo provides information for the Internet community.
RFC5008 - Suite B in Secure/Multipurpose Internet Mail Extensions (S/MIME)
This document specifies the conventions for using the United States National Security Agency's Suite B algorithms in Secure/Multipurpose Internet Mail Extensions (S/MIME) as specified in RFC 3851. This memo provides information for the Internet community.
RFC5007 - DHCPv6 Leasequery
This document specifies a leasequery exchange for the Dynamic Host Configuration Protocol for IPv6 (DHCPv6) that can be used to obtain lease information about DHCPv6 clients from a DHCPv6 server. This document specifies the scope of data that can be retrieved as well as both DHCPv6 leasequery requestor and server behavior. This document extends DHCPv6. [STANDARDS-TRACK]
RFC5006 - IPv6 Router Advertisement Option for DNS Configuration
This document specifies a new IPv6 Router Advertisement option to allow IPv6 routers to advertise DNS recursive server addresses to IPv6 hosts. This memo defines an Experimental Protocol for the Internet community.
RFC5005 - Feed Paging and Archiving
This specification defines three types of syndicated Web feeds that enable publication of entries across one or more feed documents. This includes "paged" feeds for piecemeal access, "archived" feeds that allow reconstruction of the feed's contents, and feeds that are explicitly "complete". [STANDARDS-TRACK]
RFC5004 - Avoid BGP Best Path Transitions from One External to Another
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. [STANDARDS-TRACK]
RFC5003 - Attachment Individual Identifier (AII) Types for Aggregation
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 Virtual Private 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.

RFC5002 - The Session Initiation Protocol (SIP) P-Profile-Key Private Header (P-Header)
This document specifies the SIP P-Profile-Key P-header. This header field is used in the 3rd-Generation Partnership Project (3GPP) IMS (IP Multimedia Subsystem) to provide SIP registrars and SIP proxy servers with the key of the profile corresponding to the destination SIP URI of a particular SIP request. This memo provides information for the Internet community.
RFC5001 - DNS Name Server Identifier (NSID) Option
With the increased use of DNS anycast, load balancing, and other mechanisms allowing more than one DNS name server to share a single IP 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. [STANDARDS-TRACK]
RFC5000 - Internet Official Protocol Standards
This document is published by the RFC Editor to provide a summary of the current standards protocols (as of 18 February 2008). It lists those official protocol standards, Best Current Practice, and Experimental RFCs that have not been obsoleted; it is not a complete index to the RFC series. Newly published RFCs and RFCs whose status has changed are starred.
RFC4998 - Evidence Record Syntax (ERS)
In many scenarios, users must be able prove the existence and integrity of data, including digitally signed data, in a common and reproducible way over a long and possibly undetermined period of time. This document specifies the syntax and processing of an Evidence Record, a structure designed to support long-term non-repudiation of existence of data. [STANDARDS-TRACK]
RFC4997 - Formal Notation for RObust Header Compression (ROHC-FN)
This document defines Robust Header Compression - Formal Notation (ROHC-FN), a formal notation to specify field encodings for compressed formats when defining new profiles within the ROHC framework. ROHC-FN offers a library of encoding methods that are often used in ROHC profiles and can thereby help to simplify future profile development work. [STANDARDS-TRACK]
RFC4996 - RObust Header Compression (ROHC): A Profile for TCP/IP (ROHC-TCP)
