    abstract =  {The document lists requirements for optimizations of SIP/SIMPLE. These optimizations should reduce the load on the network and the presence servers due to inter-domain presence subscriptions. The need for the requirements is based on a separate document that provides scaling analysis for inter-domain presence over SIP/SIMPLE.},
