Technical Summary
The document analyzes the traffic that is generated due to presence
subscriptions between domains. It is shown that the amount of
traffic can be extremely big. In addition to the very large traffic
the document also analyzes the affects of a large presence system on
the memory footprint and the CPU load. Current approved and in work
optimizations to the SIP protocol are analyzed with the possible
impact on the load. Separate documents contain the requirements for
optimizations and suggestions for new optimizations.
