[SR-Users] Survey on SIP overload control

[Yang Hong]

Dear all,
 
SIP overload may block too many calls unnecessarily. 
"Requirements for Management of Overload in the Session Initiation Protocol. IETF RFC 5390."
http://www.ietf.org/rfc/rfc5390.txt  Build-in overload mechanism cannot prevent overload effectively. Therefore, IETF SIP Overload Control (soc) Working Group works on IETF RFC "SIP Overload Control" currently.

http://www.ietf.org/mail-archive/web/sip-overload/current/threads.html#00874
  
We have published a survey on SIP overload control algorithms (including IETF RFC "SIP Overload Control").

We have also used control theorectic approaches to model the interactions between an overloaded SIP server and its upstream servers as a feedback control system in two different scenarios - redundant retransmission ratio control and round trip delay control (IEEE Globecom 2010 and ICC 2011).
