PBMB Algorithm Based on Message Transfer Between Date Replica in P2P Network
Jing Liu · Jisuanji gongcheng · 2008
Large-scale storage system based on P2P architecture is proposed to provide reliable and effective storage service. In these systems,the replica of data object is used to improve performance,availability and reliability. When data object changes in one of the replicas,data must be transferred to other replicas. This paper proposes a application layer multicast protocol——PBMB. Node in the system is grouped by BID. Messages are transferred by PBMB using a novel method. PBMB is self-organized,and can be used in WAN environment. Simulation shows that the algorithm is stable even in large-scale system. Messages are transferred effectively while using less node resources. PBMB is suitable for real systems in the Internet.
