Understanding BGP Session Robustness in Bandwidth Saturation Regime
The reliability and robustness of the Border Gateway Protocol (BGP) play very important roles in achieving highly stable and prompt Internet data communication. The present BGP uses TCP/IP to exchange routing control information. These routing control messages are usually not differentiated from the normal data packets in Internet packet forwarding, and this makes BGP sensitive to severe network congestion. In this paper, the authors investigate the packet drop probability and the lifetime of BGP sessions in two types of bandwidth saturation scenario.
