| Summary: |
Overload occurs in Session Initiation Protocol (SIP)
networks when proxies and user agencies have insuffient 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 draft summarizes the
problems with the existing 503 mechanism, and provides some
requirements for a solution.
