摘要:

针对域间路由系统的级联失效展开研究,分析了系统级联失效的机制,建立了域间路由系统级联失效模型。模型引入了符合节点真实信息的IRS介数,并基于IRS介数定义节点的初始负载;针对系统中节点的重启现象和BGP更新报文的交互现象,引入了节点重启时延和更新报文存活时延,使构建的级联失效模型更加符合系统的真实情况。最后,通过仿真实验分析了IRS介数与其他测度的区别,研究了不同模型参数对系统级联失效的影响。研究结果为分析和提升域间路由系统的安全性能提供了有效的参考和借鉴。

Abstract:

The cascading failures for the inter-domain routing system is researched. Based on the analysis of cascading behaviors for the inter-domain routing system, an cascading failure model for the inter-domain routing system is proposed. By introducing node’s IRS betweenness which is consistent with the inter-domain routing system, node’s initial load is defined. In order to simulate the real situation of the system, node’s restart delay and BGP update alive delay are introduced. Finally, by analyzing the difference between IRS betweenness with other node’s measurements, the impact on cascading failures of different model parameters is investigated. Moreover, research findings will provide useful guidance and reference for analyzing and improving the security of the inter-domain routing system.
