摘　　要：通信中间件由于其在屏蔽网络通信复杂性和提高系统性能等方面所起到的重要作用而被越来越广泛地应用。文章运用随机Petri网对通信中间件系统进行了描述,建立了一个实时通信中间件的同步及消息队列的模型。并对该模型的系统吞吐量、请求的平均延时等性能进行了评价,为系统的进一步设计和配置提供了理论依据。Communication middleware is becoming widely used due to its important roles of masking the complexity of network communication and improving the performance of the application system.This paper makes use of SPN to describe a real-time communication middleware system and set up a synchronization and message queue model of the real-time communication middleware.Based on which,performances are evaluated such as the system throughput and the average delay,which provide the important theoretical basis for the further design and configuration of the application system.
