AUTONOMIC OPTIMIZATION OF PRESENCE SERVER PERFORMANCE

摘要

A presence system (10) comprises a presence server (12) and a plurality of users (16) in a distributed community (14) of users that are associated with the presence server. The presence server selects a set of mediators (24), e.g., based upon a predetermined event, or other suitable factors, wherein each mediator (24) is associated with a subset (26) of the plurality of users. The presence server communicates presence information (20) to the mediators where each mediator receives presence information regarding subscribed-to presence information for the users in their associated subset of users. Each mediator communicates the subscribed-to presence information to associated ones of the users in their associated subset of users.
