Robust traffic engineering

Phenomenal growth of Internet applications in recent years have made it difficult to forecast traffic patterns. Daily Internet traffic patterns shows that the network is vulnerable to malicious attacks, flash crowds and denial of service attacks (DDoS). In this paper, we present a robust routing technique (RRT) that attempts to deal with both normal routing conditions and transient failures. Our simulation results are compared with OSPF-TE. The key advantage of RRT is its convergence to generate the solution. It converges quickly to produce the simulation result on the family of topologies we consider in this paper. We are aiming to combine the best of proactive and reactive traffic engineering in RRT.
