Analysis of BGP Routing Changes

Project Description

The performance of a backbone network is vulnerable to interdomain routing changes that affect how traffic travels to destinations in other Autonomous Systems (ASes). Despite having poor visibility into these routing changes, operators often need to react quickly by tuning the network configuration to alleviate congestion or by notifying other ASes about serious reachability problems. Fortunately, operators can improve their visibility by monitoring the Border Gateway Protocol (BGP) decisions of the routers at the periphery of their AS. However, the volume of measurement data is very large and extracting the important information is challenging. This project intends to tackle this problem by designing a system that converts millions of BGP update messages a day into a few dozen actionable reports about significant routing disruptions.
