  "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 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.",
