RTP Payload Format for mU-law EMbedded Codec for Low-delay IP Communication (UEMCLIP) Speech Codec
This document describes the RTP payload format of a mU-law EMbedded Coder for Low-delay IP communication (UEMCLIP), an enhanced speech codec of ITU-T G.711.

Redirect Mechanism for the Internet Key Exchange Protocol Version 2 (IKEv2)
The Internet Key Exchange Protocol version 2 (IKEv2) is a protocol for setting up Virtual Private Network (VPN) tunnels from a remote location to a gateway so that the VPN client can access services in the network behind the gateway. This document defines an IKEv2 extension that allows an overloaded VPN gateway or a VPN gateway that is being shut down for maintenance to redirect the VPN client to …
Unintended Consequences of NAT Deployments with Overlapping Address Space
This document identifies two deployment scenarios that have arisen from the unconventional network topologies formed using Network Address Translator (NAT) devices. First, the simplicity of administering networks through the combination of NAT and DHCP has increasingly lead to the deployment of multi-level inter-connected private networks involving overlapping private IP address spaces. Second, th…
This document proposes to add mutual authentication, based on a human-memorizable password, to the basic, unauthenticated Diffie-Hellman key exchange. The proposed algorithm is called the Password-Authenticated Key (PAK) exchange. PAK allows two parties to authenticate themselves while performing the Diffie-Hellman exchange. The protocol is secure against all passive and active attacks. In particu…
Forward RTO-Recovery (F-RTO): An Algorithm for Detecting Spurious Retransmission Timeouts with TCP
The purpose of this document is to move the F-RTO (Forward RTO-Recovery) functionality for TCP in RFC 4138 from Experimental to Standards Track status. The F-RTO support for Stream Control Transmission Protocol (SCTP) in RFC 4138 remains with Experimental status. See Appendix B for the differences between this document and RFC 4138. Spurious retransmission timeouts cause suboptimal TCP performance…
This document defines TCP's four intertwined congestion control algorithms: slow start, congestion avoidance, fast retransmit, and fast recovery.

This document examines the applicability o…
The objective of Pre-Congestion Notification (PCN) is to protect the quality of service (QoS) of inelastic flows within a Diffserv domain in a simple, scalable, and robust fashion. This document defines the two metering and marking behaviours of PCN-nodes. Threshold-metering and -marking marks all PCN-packets if the rate of PCN-traffic is greater than a configured rate ("PCN-threshold-rate"). Exce…

Parallel NFS (pNFS) extends Network File System version 4 (NFSv4) to allow clients to directly access file data on the storage used by the NFSv4 server. This ability to bypass the server for data access can increase both performance and parallelism, but requires additional client functionality for data access, some of which is dependent on the class of storage used, a.k.a. the Layout Type. The mai…

This document specifies, abstractly, how to interface applications and transport protocols with IPsec so as to create "channels" by latching "connections" (packet flows) to certain IPsec Security Association (SA) parameters for the lifetime of the connections. Connection latching is layered on top of IPsec and does not modify the underlying IPsec architecture. Connection latching can be used to pr…
An Architecture for Multi-Segment Pseudowire Emulation Edge-to-Edge
This document describes an architecture for extending pseudowire emulation across multiple packet switched network (PSN) segments. Scenarios are discussed where each segment of a given edge-to-edge emulated service spans a different provider's PSN, as are other scenarios where the emulated service originates and terminates on the same provider's PSN, but may pass through several PSN tunnel segment…
Addressing Record-Route Issues in the Session Initiation Protocol (SIP)
A typical function of a Session Initiation Protocol (SIP) Proxy is to insert a Record-Route header into initial, dialog-creating requests in order to make subsequent, in-dialog requests pass through it. This header contains a SIP Uniform Resource Identifier (URI) or SIPS (secure SIP) URI indicating where and how the subsequent requests should be sent to reach the proxy. These SIP or SIPS URIs can …
Guidance on Interoperation and Implementation Reports for Advancement to Draft Standard
Advancing a protocol to Draft Standard requires documentation of the interoperation and implementation of the protocol. Historic reports have varied widely in form and level of content and there is little guidance available to new report preparers. This document updates the existing processes and provides more detail on what is appropriate in an interoperability and implementation report. This doc…
