RFC4739 - Multiple Authentication Exchanges in the Internet Key Exchange (IKEv2) Protocol
The Internet Key Exchange (IKEv2) protocol supports several mechanisms for authenticating the parties, including signatures with public-key certificates, shared secrets, and Extensible Authentication 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 an EAP 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 memo defines an Experimental Protocol for the Internet community.
RFC4738 - MIKEY-RSA-R: An Additional Mode of Key Distribution in Multimedia Internet KEYing (MIKEY)
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 a Diffie-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's ID (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. [STANDARDS-TRACK]
RFC4737 - Packet Reordering Metrics
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. [STANDARDS-TRACK]
RFC4736 - Reoptimization of Multiprotocol Label Switching (MPLS) Traffic Engineering (TE) Loosely Routed Label Switched Path (LSP)
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 with Resource Reservation Protocol Traffic Engineering (RSVP-TE). This document proposes a mechanism that allows a TE LSP head-end Label Switching 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 (Interior Gateway Protocol area (IGP area) or Autonomous System) packet and non-packet TE LSPs following a loosely routed path. This memo provides information for the Internet community.

RFC4730 - A Session Initiation Protocol (SIP) Event Package for Key Press Stimulus (KPML)
This document describes a SIP Event Package "kpml" that enables monitoring of Dual Tone Multi-Frequency (DTMF) signals and uses Extensible Markup Language (XML) documents referred to as Key Press Markup 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 the Session 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). [STANDARDS-TRACK]

RFC4728 - The Dynamic Source Routing Protocol (DSR) for Mobile Ad Hoc Networks for IPv4
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 memo defines an Experimental Protocol for the Internet community.
RFC4727 - Experimental Values In IPv4, IPv6, ICMPv4, ICMPv6, UDP, and TCP Headers

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 the Session 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). [STANDARDS-TRACK]

RFC4728 - The Dynamic Source Routing Protocol (DSR) for Mobile Ad Hoc Networks for IPv4
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 memo defines an Experimental Protocol for the Internet community.
RFC4727 - Experimental Values In IPv4, IPv6, ICMPv4, ICMPv6, UDP, and TCP Headers
When experimenting with or extending protocols, it is often necessary to use some sort of protocol number or constant in order to actually test or experiment with the new function, even when testing in a closed environment. This document reserves some ranges of numbers for experimentation purposes in specific protocols where the need to support experimentation has been identified, and it describes the numbers that have already been reserved by other documents.
