Hi all,

As a continuation of IETF-81 Dispatch minutes (http://www.ietf.org/mail-archive/web/dispatch/current/msg03742.html) about SIP load balancing, I thought of discussing about SIP media servers load balancing as mentioned in the SIP load balancing proposed charter (http://www.ietf.org/mail-archive/web/dispatch/current/msg03615.html).

"As SIP request resource consumption in SIP signaling only server varies drastically from SIP media servers [3], should the solution be split such that load balancing of a pure signaling server is different than that of a SIP server that handles signaling as well as media?"

SIP media server load balancing solution will be different from signaling only because the downstream resource consumption is mainly because of media  (RTP) than signaling (SIP) and the units to indicate the load balancing information will be different in both solution. There is a need to indicate those media resource consumption to the load balancer in the standard manner. Please let me know your comment on this.

Thanks
