Abstract

The use of SIP [RFC3261] in large-scale Next Generation Networks requires that SIP-based networks provide adequate control mechanisms for handling traffic growth. In particular, SIP networks must be able to handle traffic overloads gracefully, maintaining transaction throughput by preventing congestion collapse.

              Session Initiation Protocol (SIP) Rate Control

Abstract

   The prevalent use of the Session Initiation Protocol (SIP) in Next    Generation Networks necessitates that SIP networks provide adequate    control mechanisms to maintain transaction throughput by preventing    congestion collapse during traffic overloads.  A loss-based solution    to remedy known vulnerabilities of the SIP 503 (Service Unavailable)    overload control mechanism has already been proposed.  Using the same    signaling, this document proposes a rate-based control scheme to    complement the loss-based control scheme.
