Hi Vijay,

1) Sec 9.1.2 Event package mechanism proposes a new event package but it does not provides the exact package for convey the overload information. Please let me whether the intention is to use "oc" parameters in Via of NOTIFY message or implementers has to choose their own event package. IMO, it is better to define some package in the standard rather than just providing the design and implementers choose the proprietary packages.

Some Editorial comments & query

2) Sec 5.4 para 2: whether overload control applies for IP or IP & port. please let me know significance of port in this context

3) Sec 5.6: "SIP server SHOULD strip the" instead "proxy SHOULD strip the"

4) Sec 5.6: Any specific reason for having "SHOULD" instead of "MUST". I'm interested in knowing whether any implementation is interested in forwarding this information to multiple hop using configuration mechanism.

5) Sec 5.7 "2nd line note" shall be added in I-D.noel-soc-overload-rate-control

6) Sec 5.10.1: It may be better to provide the recommendation for "REGISTER" message vs other message like INVITE as well. IMO, REGISTER has to be given higher priority over INVITE message in SIP servers.

Thanks
Partha
