【摘要】 分布式系统中节点之间的异步消息传递常通过消息传输代理进行。消息代理节点如果不可靠,将直接影响到消息的传递。文中提出了组代理机制,利用一组节点作为消息传输代理共同传递消息,通过增加消息传递的途径解决了由单个转发节点失效而阻碍消息传递的问题,提高了消息代理传递消息的可靠性。组代理机制实现了各节点对重复消息的正确处理,使接收节点实现了对重复消息的过滤,保证了最终接收数据的唯一性。最后通过模拟实验证明了组代理机制提高了消息代理的可靠性。更多还原

【Abstract】 Nodes in the distributed system often transfer asynchronous message through the message transfer agent.The message transfer agent was usually a single node.If the node was unreliable and easy to fail,it would affect the delivery of the messages.Proposed a new way of using a group of nodes as a message transfer agent to deliver messages,called group message transfer mechanism.It increased the reliability and prevented the delay of message transfer caused by the failure of a single node as the message transfer agent.Using a group of nodes to transfer messages would cause duplicate messages to arrive at the target node.Group message transfer mechanism provided ways to filter all the duplicate messages to ensure that no duplicate messages would be accepted by the target node.Last in this paper,the idea was proved by the experiment.更多还原
