Communication mechanism in distributed protocol testing system
Zhiliang Wang, Wu Jianping, Zhongjie Li, Xia Yin · 2004
In order to test network protocols of distributed and concurrent natures, it is necessary to introduce the distributed testing framework. In this paper, we first present a formal model of distributed testing system, and furthermore, real distributed testing system architecture is proposed. With that, we discuss communication issues between test components and a communication algorithm is given. Based on the above models and algorithm, a practical communication mechanism combining distributed message queue and shared memory is presented, which provides a uniform and transparent lower-layer communication interface for the whole test system. In our practice, this mechanism is proved to be feasible and efficient.
