Vijay, Partha, I think section 9 provides useful background on the discussions that lead to the current solution. For this reason, it would be good to keep this section in the draft. Section 9 does not refer to a specific event packet. Rather, explains general design considerations. I'd suggest the following change to Section 9.1 to point this out more clearly. 9.1. SIP Mechanism A SIP mechanism is needed to convey overload feedback from the receiving to the sending SIP entity. Developing his feedback mechanisms involves a number of fundamental design choices that are discussed in this section. Thanks, Volker On 23.04.2012 17:05, Vijay K.
