The IESG has approved the following document:
- 'Session Initiation Protocol (SIP) Rate Control'
  (draft-ietf-soc-overload-rate-control-10.txt) as Proposed Standard

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

The IESG contact persons are Richard Barnes and Alissa Cooper.

Technical Summary:

The document defines a rate-based overload control mechanism for the Session 
Initiation Protocol (SIP) to prevent signaling overload. It uses the framework 
defined in the Session Initiation Protocol (SIP) Overload Control specification 
and adds the specifications needed for a rate-based control mechanism. With 
this specification, SIP entities can choose between the loss-based overload 
control defined in Session Initiation Protocol (SIP) Overload Control and the 
rate-based overload control defined in this specification.


Working Group Summary:

The developement of this document resulted from a discussion in the WG on the 
overload feedback type (the pro's and 
con's of the feedback types discussed in Section 9. of RFC 6357). The WG 
decided to use loss-based control as the default mechanism in 
draft-ietf-soc-overload-control but allow extensions for other feedback types. 
Rate-based control was agreed as a needed extension as it has benefits in some 
scenarios. This draft provides the needed specifications for rate-based 
overload control. This draft was non-controversial and was is substantial 
interest in this specification. There was no competing proposal and it 
addresses the WG deliverable 'A specification for an SIP overload control 
mechanism based on implicit/explicit feedback'


Document Quality:
The basic mechanisms defined in this specification have been implemented and 
evaluated in several simulators as part of the work of the SIPPING Overload 
Control Design Team. The results of these evaluations were presented in several 
SIPPING WG meetings. The document has been reviewed several times as it has 
been developed by several members of the SOC WG including Salvatore Loreto, 
Janet Gunn, Christer Holmberg, James Yu, Keith Drage and Vijay Gurbani.
