ATM专用网的PNNI系统路由协议分析与研究

Analysis and Study of the Routing Protocols of PNNI System in Private ATM Network

重点分析了 ATM(Asynchronous Transfer Mode)专用通信网PNNI (Private Network－ Network/Node Interface)系统的路由协议。在考查 ATM通信网PNNI系统路由协议的基础上，提出了 ATM通信网PNNI系统中 Hello协议的研究重点和实现描述模型。最后，给出了 Hello协议采用 Petri网络描述策略的可行性 ,可靠性及正确性。

A realization description of Hello protocol forPNNI system in private ATM networks is given in this paper, and the routing protocols ofPNNI system in private ATM networks are studied in details at same time. Finally, the paper confirms the strategy's feasibility, robustness and validity.
