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. This memo provides information
for the Internet community.
