Claim Text:
1. A method implemented in a network component, the method comprising: receiving a presence information message from a previous presence server positioned at a previous hop in a ring of a plurality of presence servers, wherein the presence information message comprises presence information from a previous client coupled to the previous presence server; removing content in the presence information message that has completely traversed the ring; copying the presence information message locally for subsequent processing; receiving and buffering local presence information from a local client coupled to the network component; appending to the presence information message the buffered local presence information; and forwarding the presence information message comprising the previous client presence information and the local client presence information to a subsequent presence server positioned at a next hop in the ring, wherein forwarding the presence information message is assigned a higher priority than receiving and buffering the local presence information from the local client.
