摘要
从中间件的基本消息流入手,简单介绍了消息队列中间件中消息分发机制以及消息分发机制消息流过程。结合消息分发机制,讨论了队列式共享内存管理在中间件系统中的重要性。提出了消息队列中间件系统中消息分发器与消息队列的各种组合关系,描述了各种形式下的消息流过程,对每种方式作了详细分析和讨论,总结了各自的特点。最后,比较了它们对消息队列中间件效率、服务类型、消息优先级等的影响。
The data processes in middleware are analyzed.Then,two allocation policies,static allocation and dynamic allocation,in shared memory are referred. After discussing the importance of management of shared memory in middleware system,all kinds of relationship between message dispatcher and message queue adopted by shared memory management technology are put forward.Finally,the characteristics of all kinds of message dispatcher and message queue technology are summarized and compared
