Design considerations for Session Initiation Protocol (SIP) overload control. RFC 6537

By V. Hilt, E. Noel, C. Shen and A. Abdelal

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.
