Analysis of Security Risk Evaluation of Backbone Network Based on Petri Net
Kong Yi-yan · Journal of Hechi University · 2012
In view of the situation that the network running BPG protocol can be at risk for the CXPST attack,the paper uses network modeling tools of Petri net,and carries on modeling analysis to the topology structure of backbone network.By designing simulation tools and emulating the attack process of CXPST,feature extraction and modeling of CXPST attack process are built,thus the security risk evaluation of large-scale backbone network is realized.Simulation experiment shows that when using the simulation model built in this paper to evaluate the risk of backbone network,the accuracy rate of node failure is 84.5% and the time-delay error rate of node failure is 11.3%.
