The IESG has approved the following document:
- 'A Session Initiation Protocol (SIP) Load Control Event Package'
  (draft-ietf-soc-load-control-event-package-13.txt) as Proposed Standard

This document is the product of the SIP Overload Control Working Group.

The IESG contact persons are Richard Barnes and Gonzalo Camarillo.

A URL of this Internet Draft is:
http://datatracker.ietf.org/doc/draft-ietf-soc-load-control-event-package/




Technical Summary:

The document defines an event package for the Session Initiation Protocol (SIP) to prevent signaling overload. The load event package complements feedback-based SIP overload control mechanisms. It allows SIP entities to distribute filtering policies to other SIP entities in the network. These policies contain rules to throttle requests based on their source or destination domain, telephone number prefix or for a specific user.

Working Group Summary:
This draft complements the feedback-based SIP overload control mechanism for cases of known short-term overload (e.g., calls to a game show). This mechanism was developed in parallel to feedback-based SIP overload control and was adopted by the working group without contention.  There was no competing proposal to address the WG deliverable 'A specification for a SIP load filtering mechanism.'.

Document Quality:
The specification has been implemented and evaluated in a simulator by the main author at Columbia University. NTT strongly supports the mechanism and co-authors the specification. France Telecom Orange has indicated that they want to use this spec as a basis for a 3GPP spec. The draft was first submitted to the SIPPING WG in 2008 and moved to SOC in 2010. It has been reviewed thoroughly by several members of the SOC WG including Bruno Chatras, Janet Gunn, Shida Schubert, Phil Williams, and Adam Roach.
