Differentiated BGP Update Processing

Project Description

Real-time, multimedia applications such as IPTV, VoIP and Internet gaming are becoming popular today. These delay- and jitter-sensitive applications impose more stringent requirements on the underlying Internet routing system. In light of this trend, BGP (Border Gateway Protocol) routing issues have attracted significant attention from both the research and operator communities. A key problem associated with BGP is the excessive number of BGP updates possibly triggered by routing changes, such as session resets, link failures, and policy changes. Such excessive updates can delay routing convergence, which, in turn, degrades the performance of delay- and jitter-sensitive applications. This project intends to enhance the performance of the current BGP protocol by exploiting the idea of differentiated processing of BGP updates to reduce BGP routers’ load and improve routing convergence without changing the protocol semantics.
