RE: [Simple] Can we deprecate UDP for presence?
Are you suggesting that a sender has to look at the event
header in a SIP message before deciding which transport protocol to use, and
decide whether it is presence related.
This is an updates RFC 3261 issue, i.e. not for SIMPLE to
write the RFC, merely to determine if there are requirements in this area and
pass them to SIP.

Keith
As we know it is not easy to
scale presence.
Since presence
RFCs and drafts were created after RFC 3261 that mandates both
UDP and TCP support (opposed to
2543 that mandated only UDP), can we say that
most if not all presence client will use TCP?
If we could deprecate UDP for presence
then we can think about several traffic
optimizations where the overhead is due to the UDP support of
SIP?
Comments?
