协议分布式测试系统的性能模型

Performance Models of Protocol Distributed Test System

协议测试领域专家们已经达成共识 :新一代的协议测试系统应该是分布式架构的。本文用广义随机Petri网 (GSPN )对目前提出的几种协议分布式测试框架构造了性能模型 ,进行了性能比较和分析。为了解决状态空间爆炸的问题 ,提出了一种同步变迁实施速率等价法 (STER) ,这种方法能够对具有同步变迁的随机Petri网模型分解求解。

It is believed in the area of protocol testing that next generation protocol test systems should be distributed. Performance models of various frameworks of protocol distributed testing are established in the Generalized Stochastic Petri Nets (GSPN) and solved with a decomposition approach called Synchronized Transition Equivalent Rate (STER), which is proposed in this paper and can be applied to GSPN models with synchronous transitions, especially such models with isomorphic sub-models. Some simulation results and performance comparisons are also presented.
