A new Request for Comments is now available in online RFC libraries. RFC 5923 Title: Connection Reuse in the Session Initiation Protocol (SIP) Author: V. Gurbani, Ed., R. Mahy, B. Tate Status: Standards Track Stream: IETF Date: June 2010 Mailbox: vkg@alcatel-lucent.com, rohan@ekabal.com, brett@broadsoft.com Pages: 19 Characters: 41905 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-sip-connect-reuse-14.txt URL: http://www.rfc-editor.org/rfc/rfc5923.txt This document enables a pair of communicating proxies to reuse a congestion-controlled connection between themselves for sending requests in the forwards and backwards direction. Because the connection is essentially aliased for requests going in the backwards direction, reuse is predicated upon both the communicating endpoints authenticating themselves using X.509 certificates through Transport Layer Security (TLS). For this reason, we only consider connection reuse for TLS over TCP and TLS over Stream Control Transmission Protocol (SCTP). This document also provides guidelines on connection reuse and virtual SIP servers and the interaction of connection reuse and DNS SRV lookups in SIP. [STANDARDS TRACK] This document is a product of the Reliable Multicast Transport Working Group of the IETF. This is now a Proposed Standard Protocol. STANDARDS TRACK: This document specifies an Internet standards track protocol for the Internet community,and requests discussion and suggestions for improvements.
