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.
This document is a product of the SIP Overload Control Working Group of the IETF.
This is now a Proposed Standard.
