Abstract:
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 defines the behaviour of SIP servers involved in overload
control, and in addition, it specifies a loss-based overload scheme
for SIP.
