Abstract

We propose an approach to efficiently identify and substitute alternate paths in resilient Web infrastructure using overlay networks for reliable information access. Our approach is based on scalable topology-independent analysis of network behavior to identify dependencies among paths in the overlay network. Such dependencies can be characterized as non-random associations between client/server pairs and will be measured using correlation and mutual information metrics. We demonstrate that these metrics reflect physical topology characteristics, e,g., the overlap of BGP paths.
