Overload occurs in Session Initiation Protocol (SIP) networks when
SIP servers have insufficient resources to handle all SIP messages
they receive.  Even though the SIP protocol provides a limited
overload control mechanism through its 503 (Service Unavailable)
response code, SIP servers are still vulnerable to overload.  This
document discusses models and design considerations for a SIP
overload control mechanism.  This document is not an Internet 
Standards Track specification; it is published for informational purposes.

This document is a product of the SIP Overload Control Working Group of the IETF.
