A new Request for Comments is now available in online RFC libraries. RFC 5390 Title: Requirements for Management of Overload in the Session Initiation Protocol Author: J. Rosenberg Status: Informational Date: December 2008 Mailbox: jdrosen@cisco.com Pages: 14 Characters: 32851 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-sipping-overload-reqs-05.txt URL: http://www.rfc-editor.org/rfc/rfc5390.txt Overload occurs in Session Initiation Protocol (SIP) networks when proxies and user agents have insufficient resources to complete the processing of a request. SIP provides limited support for overload handling through its 503 response code, which tells an upstream element that it is overloaded. However, numerous problems have been identified with this mechanism. This document summarizes the problems with the existing 503 mechanism, and provides some requirements for a solution.
