Research on Validation of Cascading Failure Model of Inter-domain Routing System

In recent years, research on cascading failure phenomena of inter-domain routing systems has gradually increased, mainly focusing on the establishment of cascading failure models and BGP vulnerability analysis, but there are still few studies on the validation of cascading failure models. However, It is necessary to verify the established cascading failure simulation model. In this paper, the CODE REDvirus incident that once broke out in the inter-domain routing network is used as the real data support, and the update message is selected as the statistical indicator to compare and analyze the update message changes generated by the simulation of different cascading failure models. We establish evaluation indicators to quantify the simulation accuracy of different models. By evaluating the accuracy of simulation of cascading failure models with different recovery mechanisms, it is found that the model that generates update messages when the BGP session is reset is more in line with the changes in the update messages when cascading failures occur in real networks. Under the circumstances, the simulation model has higher accuracy and rationality.
