Thus, a modern distributed application relies heavily on reliable message transfer service 基于消息的分布式应用需要可靠的消息传输服务。
However, the infrastructures of distributed systems are inherently fault-prone, which brings a serious challenge to the implementation of reliable message transfer service 然而分布系统比集中式系统具有更多的故障。这些故障对设计和实现一个可靠的消息传递服务提出了挑战。
As a component of message oriented middleware ismq, message transfer agent ( mta ), which implements reliable message transfer service, delivers messages among ismq servers . based on the study of failure models, we introduced a reliable message transfer protocol in mta 消息传输代理mta是消息中间件ismq中的一个子系统,该子系统完成消息在服务器和服务器之间转发的功能,是分布式系统结点间可靠消息传输的实现。
