【摘要】 提出基于P2P网络技术构建Web服务通告代理集群,同时,提出对通告代理集群进行基于主题的逻辑多层管理,在主题层内使用层内通告消息广播算法传播通告消息.仿真结果表明,通告代理集群对随机节点故障是强壮的,基于主题的分层技术有效减少了每个通告代理节点的负载,层内通告消息广播算法具有高可靠性和好的可扩展能力.更多还原

【Abstract】 This paper proposed notificationbroker cluster in WS-notification service built on Peer-to-Peer technique,and it has good dynamic characteristic,good scalability and is robust to random node failure.It was also proposed that notificationbroker cluster is managed as a logical multi-layer system based on topic.A gossip-based broadcast algorithm is designed for spreading notification message in the topic layer.The experimental results show that the notificationbroker network is robust to random node failure,the load of each notificationbroker node is effectively reduced by the layering technique based on topics,and the topic-layer broadcast algorithm has high reliability.更多还原
