It is possible for Dynamic Host Configuration Protocol (DHCP) clients to attempt to update the same DNS Fully Qualified Domain Name (FQDN) or to update a DNS FQDN that has been added to the DNS for another purpose as they obtain DHCP leases. Whether the DHCP server or the clients themselves perform the DNS updates, conflicts can arise. To resolve such conflicts, RFC 4703 proposes storing client identifiers in the DNS to unambiguously associate domain names with the DHCP clients to which they refer. This memo defines a distinct ResourceRecord (RR) type for this purpose for use by DHCP clients and servers: the "DHCID" RR. |

The Dynamic Host Configuration Protocol (DHCP) provides a mechanism for host configuration that includes dynamic assignment of IP addresses and fully qualified domain names. To maintain accurate name-to-IP-address and IP-address-to-name mappings in the DNS, these dynamically assigned addresses and fully qualified domain names(FQDNs) require updates to the DNS. This document identifies situations in which conflicts in the use of fully qualified domain names may arise among DHCP clients and servers, and it describes a strategy for the use of the DHCID DNS resource record (RR) in resolving those conflicts. |

|
The Netnews Administration System (NAS) is a framework to simplify the administration and usage of network news (also known as Netnews) on the Internet. Data for the administration of newsgroups and hierarchies are kept in a distributed hierarchical database and are available through a client-server protocol.
The database is accessible by news servers, news administrators, and news readers. News servers can update their configuration automatically; administrators are able to get the data manually.News reader programs are able to get certain information from an NAS server, automatically or at a user's discretion, which provides detailed information about groups and hierarchies to the user.
NAS is usable in coexistence with the current, established process of control messages; an unwanted interference is impossible.Furthermore, NAS is able to reflect the somewhat chaotic structure ofUsenet in a hierarchical database. NAS can be used without modification of existing news relay, news server, or news reader software; however, some tasks will be better accomplished with NAS- compliant software. |

In current Web browsers, there is no uniform way to specify that a user clicking on a link will be presented with an editable view of aWeb Distinguished Authoring and Versioning (WebDAV) server. For example, it is frequently desirable to be able to click on a link and have this link open a window that can handle drag-and-drop interaction with the resources of a WebDAV server.
This document specifies a mechanism and a document format that enables WebDAV servers to send "mounting" information to a WebDAV client. The mechanism is designed to work on any platform and with any combination of browser and WebDAV client, relying solely on the well-understood dispatch of documents through their MIME type. |

| RFC 4721 | Mobile IPv4 Challenge/Response Extensions (Revised) |
| |
|
|
Mobile IP, as originally specified, defines an authentication extension (the Mobile-Foreign Authentication extension) by which a mobile node can authenticate itself to a foreign agent.Unfortunately, that extension does not provide the foreign agent any direct guarantee that the protocol is protected from replays and does not allow for the use of existing techniques (such as ChallengeHandshake Authentication Protocol (CHAP)) for authenticating portable computer devices.
In this specification, we define extensions for the Mobile IP AgentAdvertisements and the Registration Request that allow a foreign agent to use a challenge/response mechanism to authenticate the mobile node.
Furthermore, this document updates RFC 3344 by including a new authentication extension called the Mobile-Authentication,Authorization, and Accounting (AAA) Authentication extension. This new extension is provided so that a mobile node can supply credentials for authorization, using commonly available AAA infrastructure elements. This authorization-enabling extension MAY co-exist in the same Registration Request with authentication extensions defined for Mobile IP Registration by RFC 3344. This document obsoletes RFC 3012. |

This document describes a mechanism for BGP that would help minimize the negative effects on routing caused by BGP restart. An End-of-RIB marker is specified and can be used to convey routing convergence information. A new BGP capability, termed "Graceful RestartCapability", is defined that would allow a BGP speaker to express its ability to preserve forwarding state during BGP restart. Finally, procedures are outlined for temporarily retaining routing information across a TCP session termination/re-establishment.
The mechanisms described in this document are applicable to all routers, both those with the ability to preserve forwarding state during BGP restart and those without (although the latter need to implement only a subset of the mechanisms described in this document). |

| RFC 4728 | The Dynamic Source Routing Protocol (DSR) for Mobile Ad Hoc Networks for IPv4 |

| Status: | EXPERIMENTAL |
| DOI: | 10.17487/RFC 4728 |
|
The Dynamic Source Routing protocol (DSR) is a simple and efficient routing protocol designed specifically for use in multi-hop wireless ad hoc networks of mobile nodes. DSR allows the network to be completely self-organizing and self-configuring, without the need for any existing network infrastructure or administration. The protocol is composed of the two main mechanisms of "Route Discovery" and"Route Maintenance", which work together to allow nodes to discover and maintain routes to arbitrary destinations in the ad hoc network.All aspects of the protocol operate entirely on demand, allowing the routing packet overhead of DSR to scale automatically to only what is needed to react to changes in the routes currently in use. The protocol allows multiple routes to any destination and allows each sender to select and control the routes used in routing its packets, for example, for use in load balancing or for increased robustness.Other advantages of the DSR protocol include easily guaranteed loop- free routing, operation in networks containing unidirectional links, use of only "soft state" in routing, and very rapid recovery when routes in the network change. The DSR protocol is designed mainly for mobile ad hoc networks of up to about two hundred nodes and is designed to work well even with very high rates of mobility. This document specifies the operation of the DSR protocol for routing unicast IPv4 packets. |

This document describes a SIP Event Package "kpml" that enables monitoring of Dual Tone Multi-Frequency (DTMF) signals and usesExtensible Markup Language (XML) documents referred to as Key PressMarkup Language (KPML). The kpml Event Package may be used to support applications consistent with the principles defined in the document titled "A Framework for Application Interaction in theSession Initiation Protocol (SIP)". The event package uses SUBSCRIBE messages and allows for XML documents that define and describe filter specifications for capturing key presses (DTMF Tones) entered at a presentation-free User Interface SIP User Agent (UA). The event package uses NOTIFY messages and allows for XML documents to report the captured key presses (DTMF tones), consistent with the filter specifications, to an Application Server. The scope of this package is for collecting supplemental key presses or mid-call key presses(triggers). |

| RFC 4733 | RTP Payload for DTMF Digits, Telephony Tones, and Telephony Signals |
| |
|
|
This memo describes how to carry dual-tone multifrequency (DTMF) signalling, other tone signals, and telephony events in RTP packets.It obsoletes RFC 2833.
This memo captures and expands upon the basic framework defined inRFC 2833, but retains only the most basic event codes. It sets up anIANA registry to which other event code assignments may be added.Companion documents add event codes to this registry relating to modem, fax, text telephony, and channel-associated signalling events.The remainder of the event codes defined in RFC 2833 are conditionally reserved in case other documents revive their use.
This document provides a number of clarifications to the original document. However, it specifically differs from RFC 2833 by removing the requirement that all compliant implementations support the DTMF events. Instead, compliant implementations taking part in out-of-band negotiations of media stream content indicate what events they support. This memo adds three new procedures to the RFC 2833 framework: subdivision of long events into segments, reporting of multiple events in a single packet, and the concept and reporting of state events. |

|
This document defines a mechanism for the reoptimization of loosely routed MPLS and GMPLS (Generalized Multiprotocol Label Switching)Traffic Engineering (TE) Label Switched Paths (LSPs) signaled withResource Reservation Protocol Traffic Engineering (RSVP-TE). This document proposes a mechanism that allows a TE LSP head-end LabelSwitching Router (LSR) to trigger a new path re-evaluation on every hop that has a next hop defined as a loose or abstract hop and a mid-point LSR to signal to the head-end LSR that a better path exists(compared to the current path) or that the TE LSP must be reoptimized(because of maintenance required on the TE LSP path). The proposed mechanism applies to the cases of intra- and inter-domain (InteriorGateway Protocol area (IGP area) or Autonomous System) packet and non-packet TE LSPs following a loosely routed path. |

This memo defines metrics to evaluate whether a network has maintained packet order on a packet-by-packet basis. It provides motivations for the new metrics and discusses the measurement issues, including the context information required for all metrics. The memo first defines a reordered singleton, and then uses it as the basis for sample metrics to quantify the extent of reordering in several useful dimensions for network characterization or receiver design.Additional metrics quantify the frequency of reordering and the distance between separate occurrences. We then define a metric oriented toward assessment of reordering effects on TCP. Several examples of evaluation using the various sample metrics are included.An appendix gives extended definitions for evaluating order with packet fragmentation. |

The Multimedia Internet Keying (MIKEY) specification describes several modes of key distribution solution that address multimedia scenarios (e.g., SIP calls and Real Time Streaming Protocol (RTSP) sessions) using pre-shared keys, public keys, and optionally aDiffie-Hellman key exchange. In the public-key mode, the Initiator encrypts a random key with the Responder's public key and sends it to the Responder. In many communication scenarios, the Initiator may not know the Responder's public key, or in some cases the Responder'sID (e.g., call forwarding) in advance. We propose a new MIKEY mode that works well in such scenarios. This mode also enhances the group key management support in MIKEY; it supports member-initiated group key download (in contrast to group manager pushing the group keys to all members). This document updates RFC 3830 with the RSA-R mode. |

| RFC 4739 | Multiple Authentication Exchanges in the Internet Key Exchange (IKEv2) Protocol |
| |
| Authors: | P. Eronen, J. Korhonen. |

| Formats: | txt json html |
| Status: | EXPERIMENTAL |
| DOI: | 10.17487/RFC 4739 |
|
The Internet Key Exchange (IKEv2) protocol supports several mechanisms for authenticating the parties, including signatures with public-key certificates, shared secrets, and ExtensibleAuthentication Protocol (EAP) methods. Currently, each endpoint uses only one of these mechanisms to authenticate itself. This document specifies an extension to IKEv2 that allows the use of multiple authentication exchanges, using either different mechanisms or the same mechanism. This extension allows, for instance, performing certificate-based authentication of the client host followed by anEAP authentication of the user. When backend authentication servers are used, they can belong to different administrative domains, such as the network access provider and the service provider. |

|
This document constitutes Revision 1 of Cryptographic Token KeyInitialization Protocol (CT-KIP) Version 1.0 from RSA Laboratories'One-Time Password Specifications (OTPS) series. The body of this document, except for the intellectual property considerations section, is taken from the CT-KIP Version 1.0 document, but comments received during the IETF review are reflected; hence, the status of a revised version. As no "bits-on-the-wire" have changed, the protocol specified herein is compatible with CT-KIP Version 1.0.
CT-KIP is a client-server protocol for initialization (and configuration) of cryptographic tokens. The protocol requires neither private-key capabilities in the cryptographic tokens, nor an established public-key infrastructure. Provisioned (or generated) secrets will only be available to the server and the cryptographic token itself. |

This document defines a new parameter "enumdi" for the "tel" UniformResource Identifier (URI) to support the handling of ENUM queries inVoice over Internet Protocol (VoIP) network elements. A VoIP network element may receive a URI containing an E.164 number, where that URI contains an "enumdi" parameter. The presence of the "enumdi" parameter indicates that an ENUM query has already been performed on the E.164 number by a previous VoIP network element. Equally, if aVoIP network element sends such a URI, it asserts that an ENUM query has been carried out on this number. |

| RFC 4761 | Virtual Private LAN Service (VPLS) Using BGP for Auto-Discovery and Signaling |
| |
|
|
Virtual Private LAN Service (VPLS), also known as Transparent LANService and Virtual Private Switched Network service, is a usefulService Provider offering. The service offers a Layer 2 VirtualPrivate Network (VPN); however, in the case of VPLS, the customers in the VPN are connected by a multipoint Ethernet LAN, in contrast to the usual Layer 2 VPNs, which are point-to-point in nature.
This document describes the functions required to offer VPLS, a mechanism for signaling a VPLS, and rules for forwarding VPLS frames across a packet switched network. |

|
This document describes a Virtual Private LAN Service (VPLS) solution using pseudowires, a service previously implemented over other tunneling technologies and known as Transparent LAN Services (TLS).A VPLS creates an emulated LAN segment for a given set of users; i.e., it creates a Layer 2 broadcast domain that is fully capable of learning and forwarding on Ethernet MAC addresses and that is closed to a given set of users. Multiple VPLS services can be supported from a single Provider Edge (PE) node.
This document describes the control plane functions of signaling pseudowire labels using Label Distribution Protocol (LDP), extendingRFC 4447. It is agnostic to discovery protocols. The data plane functions of forwarding are also described, focusing in particular on the learning of MAC addresses. The encapsulation of VPLS packets is described by RFC 4448. |

|
The Generic Security Services API (GSS-API) provides a naming architecture that supports name-based authorization. GSS-API authenticates two named parties to each other. Names can be stored on access control lists (ACLs) to make authorization decisions.Advances in security mechanisms and the way implementers wish to useGSS-API require this model to be extended for the next version ofGSS-API. As people move within an organization or change their names, the name authenticated by GSS-API may change. Using some sort of constant identifier would make ACLs more stable. Some mechanisms, such as public-key mechanisms, do not have a single name to be used across all environments. Other mechanisms, such as Kerberos, may include group membership or role information as part of authentication. This document motivates extensions to GSS-API naming and describes the extensions under discussion. |

The Data Encryption Standard (DES) is susceptible to brute-force attacks, which are well within the reach of a modestly financed adversary. As a result, DES has been deprecated, and replaced by theAdvanced Encryption Standard (AES). Nonetheless, many applications continue to rely on DES for security, and designers and implementers continue to support it in new applications. While this is not always inappropriate, it frequently is. This note discusses DES security implications in detail, so that designers and implementers have all the information they need to make judicious decisions regarding its use. |

This document discusses procedural issues related to the extensibility of IETF protocols, including when it is reasonable to extend IETF protocols with little or no review, and when extensions or variations need to be reviewed by the IETF community. Experience has shown that extension of protocols without early IETF review can carry risk. The document also recommends that major extensions to or variations of IETF protocols only take place through normal IETF processes or in coordination with the IETF.
This document is directed principally at other Standards DevelopmentOrganizations (SDOs) and vendors considering requirements for extensions to IETF protocols. It does not modify formal IETF processes. |

A mechanism for BGP that helps minimize the negative effects on routing caused by BGP restart has already been developed and is described in a separate document ("Graceful Restart Mechanism forBGP"). This document extends this mechanism to minimize the negative effects on MPLS forwarding caused by the Label Switching Router's(LSR's) control plane restart, and specifically by the restart of itsBGP component when BGP is used to carry MPLS labels and the LSR is capable of preserving the MPLS forwarding state across the restart.
The mechanism described in this document is agnostic with respect to the types of the addresses carried in the BGP Network LayerReachability Information (NLRI) field. As such, it works in conjunction with any of the address families that could be carried inBGP (e.g., IPv4, IPv6, etc.). |

This document specifies an optional Quick-Start mechanism for transport protocols, in cooperation with routers, to determine an allowed sending rate at the start and, at times, in the middle of a data transfer (e.g., after an idle period). While Quick-Start is designed to be used by a range of transport protocols, in this document we only specify its use with TCP. Quick-Start is designed to allow connections to use higher sending rates when there is significant unused bandwidth along the path, and the sender and all of the routers along the path approve the Quick-Start Request.
This document describes many paths where Quick-Start Requests would not be approved. These paths include all paths containing routers,IP tunnels, MPLS paths, and the like that do not support Quick-Start. These paths also include paths with routers or middleboxes that drop packets containing IP options. Quick-Start Requests could be difficult to approve over paths that include multi-access layer- two networks. This document also describes environments where theQuick-Start process could fail with false positives, with the sender incorrectly assuming that the Quick-Start Request had been approved by all of the routers along the path. As a result of these concerns, and as a result of the difficulties and seeming absence of motivation for routers, such as core routers to deploy Quick-Start, Quick-Start is being proposed as a mechanism that could be of use in controlled environments, and not as a mechanism that would be intended or appropriate for ubiquitous deployment in the global Internet. |

| RFC 4783 | GMPLS - Communication of Alarm Information |
| |
|
|
This document describes an extension to Generalized MPLS (Multi-Protocol Label Switching) signaling to support communication of alarm information. GMPLS signaling already supports the control of alarm reporting, but not the communication of alarm information. This document presents both a functional description and GMPLS-RSVP specifics of such an extension. This document also proposes modification of the RSVP ERROR_SPEC object.
This document updates RFC 3473, "Generalized Multi-Protocol LabelSwitching (GMPLS) Signaling Resource ReserVation Protocol-TrafficEngineering (RSVP-TE) Extensions", through the addition of new, optional protocol elements. It does not change, and is fully backward compatible with, the procedures specified in RFC 3473. |

| RFC 4787 | Network Address Translation (NAT) Behavioral Requirements for Unicast UDP |
| |
|
|
This document defines basic terminology for describing different types of Network Address Translation (NAT) behavior when handlingUnicast UDP and also defines a set of requirements that would allow many applications, such as multimedia communications or online gaming, to work consistently. Developing NATs that meet this set of requirements will greatly increase the likelihood that these applications will function properly. |

| RFC 4788 | Enhancements to RTP Payload Formats for EVRC Family Codecs |
| |
|
|
This document updates the Enhanced Variable Rate Codec (EVRC) RTP payload formats defined in RFC 3558 with several enhancements and extensions. In particular, it defines support for the header-free and interleaved/bundled packet formats for the EVRC-B codec, a new compact bundled format for the EVRC and EVRC-B codecs, as well as discontinuous transmission (DTX) support for EVRC and EVRC-B-encoded speech transported via RTP. Voice over IP (VoIP) applications operating over low bandwidth dial-up and wireless networks require such enhancements for efficient use of the bandwidth. |

|
Many Internet application protocols include string-based lookup, searching, or sorting operations. However, the problem space for searching and sorting international strings is large, not fully explored, and is outside the area of expertise for the InternetEngineering Task Force (IETF). Rather than attempt to solve such a large problem, this specification creates an abstraction framework so that application protocols can precisely identify a comparison function, and the repertoire of comparison functions can be extended in the future. |

| RFC 4792 | Encoding Instructions for the Generic String Encoding Rules (GSER) |
| |
|
|
Abstract Syntax Notation One (ASN.1) defines a general framework for annotating types in an ASN.1 specification with encoding instructions that alter how values of those types are encoded according to ASN.1 encoding rules. This document defines the supporting notation for encoding instructions that apply to the Generic String Encoding Rules(GSER) and, in particular, defines an encoding instruction to provide a machine-processable representation for the declaration of a GSERChoiceOfStrings type. |

| RFC 4794 | RFC 1264 Is Obsolete |
| |
|
|
RFC 1264 was written during what was effectively a completely different time in the life of the Internet. It prescribed rules to protect the Internet against new routing protocols that may have various undesirable properties. In today's Internet, there are so many other pressures against deploying unreasonable protocols that we believe that existing controls suffice, and the RFC 1264 rules just get in the way. |

| RFC 4795 | Link-local Multicast Name Resolution (LLMNR) |
| |
| Authors: | B. Aboba, D. Thaler, L. Esibov. |

| Status: | INFORMATIONAL |
| DOI: | 10.17487/RFC 4795 |
|
The goal of Link-Local Multicast Name Resolution (LLMNR) is to enable name resolution in scenarios in which conventional DNS name resolution is not possible. LLMNR supports all current and futureDNS formats, types, and classes, while operating on a separate port from DNS, and with a distinct resolver cache. Since LLMNR only operates on the local link, it cannot be considered a substitute forDNS. |

| RFC 4796 | The Session Description Protocol (SDP) Content Attribute |
| |
| Authors: | J. Hautakorpi, G. Camarillo. |
| Date: | February 2007 |
| Formats: | txt json html |
| Status: | PROPOSED STANDARD |
| DOI: | 10.17487/RFC 4796 |
|
This document defines a new Session Description Protocol (SDP) media- level attribute, 'content'. The 'content' attribute defines the content of the media stream to a more detailed level than the media description line. The sender of an SDP session description can attach the 'content' attribute to one or more media streams. The receiving application can then treat each media stream differently(e.g., show it on a big or small screen) based on its content. |

| RFC 4798 | Connecting IPv6 Islands over IPv4 MPLS Using IPv6 Provider Edge Routers (6PE) |
| |

| Date: | February 2007 |
| Formats: | txt html json |
| Status: | PROPOSED STANDARD |
| DOI: | 10.17487/RFC 4798 |
|
This document explains how to interconnect IPv6 islands over aMultiprotocol Label Switching (MPLS)-enabled IPv4 cloud. This approach relies on IPv6 Provider Edge routers (6PE), which are DualStack in order to connect to IPv6 islands and to the MPLS core, which is only required to run IPv4 MPLS. The 6PE routers exchange the IPv6 reachability information transparently over the core using theMultiprotocol Border Gateway Protocol (MP-BGP) over IPv4. In doing so, the BGP Next Hop field is used to convey the IPv4 address of the6PE router so that dynamically established IPv4-signaled MPLS LabelSwitched Paths (LSPs) can be used without explicit tunnel configuration. |
