基于随机Petri网的BGP网络安全评估

BGP Network Security Assessment Based on Stochastic Petri Nets

随机Petri网因其具有坚实的理论基础、强大的分析功能和易于表达的图形化方式,应用比较广泛。介绍了基于随机Petri网的网络安全评价技术和方法,并对评估的主要性能指标进行了论述。在此基础上对构建的一个BGP网络进行了评估,给出了实验结果,实验中得到的统计数据与实际网络状况相符。由此,该评估实验与评估技术得到了实证。

Stochastic Petri Net is preferable because of its solid mathematical foundation, its powerful analysis ability and its simple graphic structure. The paper focuses on network security assessment techniques based on Stochastic Petri Net and provides insight into attributes related to security. On this basis, a BGP network is built to assess, and the assessment results are attained. In the testing case, the collected data matches with the network status. Thus, the proposed testing and assessment techniques are verified.
