摘要
在给出会话初始化协议(SIP)的服务工作过程的基础上,建立了SIP的广义随机Petri网模型(GSPN),利用广义随机Petri网坚实的数学基础和分析技术完成对会话初始化协议的分析验证和性能分析。通过可达性分析、S_不变量分析和T_不变量分析验证了会话初始化协议的有界性、活性、守恒性和循环性。并且构造出与广义随机Petri模型同构的马尔可夫链,基于马尔可夫链的稳定状态概率进行系统性能分析。对会话初始化协议相关研究以及解决实际问题具有一定的理论价值。
On the basis of the process of Session Initiation Protocol's service, generalized stochastic Petri net model of SIP was established. Through the analysis of reachability and invariant the protocol was proved to be boundedness, deadlock free, liveness and conservativeness, Moreover, Markov chain of the model was constructed, In terms of properties of generalized stochastic Petri net and mathematical theory, performance of the protocol is analyzed, which was given to verify the feature of the protocol. This paper was of great academic value to solve the problem of SIP's application.
