摘　　要：服务元是近期开始研究的一种非层次网络体系结构,采用虚电路VC(V irtual C ircu it)结构。如用于专用的测控网络系统,能提高其实时性能。针对测控网络的服务元体系结构用着色Petri网CPN(Colored PetriNet)建模,采用的不是通常自顶而下分级的方法,而是提出了统一建模的思想,用少量复杂的库所、变迁表示模型,给出了网络界熟悉的收发操作算法,提出了两次握手协议和六次握手协议。测控网络采用VC结构,能提高测控网络的实时服务质量QoS(Quality of Server),用CPN工具建模仿真可分析测控网络的性能。To adopt VC （Virtual Circuit） structure, service unit is researched for a non-hierarchy network architecture recently. If use to be the specialized test and control network system, it can improve the real-time performance. To ann at test and control network＇s service unit architecture CPN （Colored Petri Net） modeling, a top-down classification approach was not adopted, in contrast, the idea of unification modeling was provided. The model was represented with a few sophisticated place and transition. The recelve-send algorithm was provided. The two-way and six-way handshake protocol was put forward. To adopt VC structure, the quality of realtime server of test and control network can enhance. The performance of test and control network can be analyzed with CPN tools modeling and simulation.
