Executive Summary

To improve routing security in MPLS network, base on the stochastic routing algorithm, the authors propose a proactive mechanism they call Enhanced Secure Heuristic-Stochastic Routing (ESHSR), which brings to bear Bayesian principle, explores the existence of multiple routes and forces packets to take alternate paths probabilistically. In this paper, the authors investigate game theoretic techniques to develop routing policies which make interception and eavesdropping maximally difficult. Through simulations, they validate their theoretical results and show how the resulting routing algorithms perform in terms of the security/delay/drop-rate, and they contrast them with the mechanism, Secure Stochastic Routing (SSR).
