BGP is High on SDN: Improving BGP Convergence and Security using SDN and Reassertions

We present a novel way where we dissipate BGP state change messages from multiple Autonomous Systems (ASes). This results in multiplication of BGP propagation effort. We used OpenFlow capable routers distributed across the internet to optimally automate this process. Our approach also helps to mitigate IP prefix hijack and Multiple Origion Autonomous System (MOAS) conflicts (quantify). We used Oregon RouteViews in our simulations. Experimental results showed that this scheme can significantly increase BGP propagation (quantify) and alleviate BGP security issues (quantify). It is applicable to most of the internet. Our approach is also endorsed by mathematical models.
