Design of Dynamic Group Communication

概要

論文の詳細を見る
In group communication, the configuration of a cluster, i.e. group of entities, may change by some events like entity failure. In some applications, there are cases that the remaining operational entities can continue to communicate with each other even if some entities fail, i.e. stop communication. On the other hand, some entity may join and leave the cluster. discusses a total receipt ordering (TO) protocol where every entity receives all the Protocol data units (PDUs) broadcast in the cluster in the same order preserving the sending order. In this paper, we would like to discuss a protocol which provides the TO service even if the cluster configuration changes. In this paper, we present two kinds of dynamic aspects of group communication. In the first aspect, entities in the cluster may fail and then recover from it. In the other aspect, entities may join and leave the cluster. We present TO protocols for such dynamic cluster. In section 2,we present our system model. In section 3,we discuss properties of dynamic cluster in this paper. In section 4and 5,we discuss two dynamic aspects. In section 6,we discuss how to manage clusters in the system.
