Object-based group protocol

摘要

In traditinal group protocols,messages ar causally delivered at the netowrk levle.In order to reduce the protocol overhead,only messages required to be causally delivered at the appcliation level have to be ordered.The state of the object depends on in what order the requrests and responses are exchanged and the requriests are computed.In this paper,we fefine a novel significant precedence roder of messages based on the conflicting relation among the requests.We discuss a protocol which supports the significantly ordered delivery of request and response messages.
