网络化测试系统中间件的研究与设计

Research and design of middleware in network test system

针对网络化测试系统中测试设备种类繁多、总线结构和测试平台各不相同的问题,研究了基于面向服务体系结构(SOA)的网络化测试系统消息中间件(MOM)。将SOA与MOM相结合,设计了该中间件的体系结构,给出了消息发布和订阅的流程,并对消息的格式进行了详细定义,结合实例,验证了该模型的有可行性和有效性。实验结果表明,该中间件为网络测试系统的各个测试设备提供了一种公用的信息通信方式,可以有效地解决网络化测试系统中的跨平台数据交换和通讯问题。

Aiming at the various devices, bus structure and platform in network test system, the message oriented middleware （MOM） based on service oriented architecture （SOA） is studied, which combines SOA with MOM. The flow of message publication and subscription is introduced, and the format of message is prescribed in detail. Finally, the validity and efficiency of the middleware model is demonstrated by case ofprototype system. Experiments showed that the proposed middleware provides a kind of public communicated way for devices at the network test system, which can effectively solve the problem of cross-platform data exchanging and communicating.
