Most services discuss with a specific target on a specific +service. + +However, we still have lots of discussion for the "world service", +i.e. the service which "simulates" the world and run the various objects +and NPC agents. That one might be a candidate for a multicast protocol, +since we can expect replication of objects across multiple world services. + +This tie in with another question which I didn't had time to reply to, +regarding how to "split" the world across the multiple world services. +If the split is done by geography (the UO model), then there is little +need of a PGM-based protocol, because most objects will be accessed by +2 world services (edges), or at most 3 (T-intersections). However, if the +split is done instead by reference (i.e. we cluster an agent with the +agents that refer to it more often), then we have a higher redundancy +of agents on servers, and a multicast is probably the best method to +send message to these agents. + +-- +Vincent Archer Email: <A HREF="mailto:archer@nevrax.com">archer@nevrax.com</A> + +Nevrax France.
