Root cause analysis of BGP updates is the key to debug and troubleshoot BGP routing problems. However, accurately inferring what is the cause of routing instability and where it originate is very hard. In this paper, we present a novel approach to locate the origin of routing instability by analyzing the relationship of the closed loops formed by intersecting the all the paths in path exploration...
Root cause analysis of BGP updates is the key to debug and troubleshoot BGP routing problems. However, inferring the root cause with high accuracy is challenge. Although correlating multiple vantage points is a validate method, how many vantage points are truly necessary to pinpoint the root cause is not resolved. In this paper, we propose a new method to explore two independent vantage points to...
