Design Considerations for Session Initiation Protocol Overload Control
RFC 6357, “Design Considerations for Session Initiation Protocol Overload Control”, is an Informational document published in August 2011 by V. Hilt, E. Noel, C. Shen, A. Abdelal. The canonical text is published by the RFC Editor.
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.
What “Informational” means
Published for the general information of the community. It does not define an IETF standard and carries no standards-track status.
