Abstract

In this short paper we present a preliminary study of the impact of large-scale failures on communication networks. Models for study of large-scale failures are studied and unique characteristics of these scenarios as well as their differences with independent multiple-failure scenarios are presented. In particular, we focus on regional large-scale failure scenarios in which node/link failures are location-dependent. Methods for restoration of traffic and the issue of failure notification time are examined. The regional failure scenario is examined on a sample backbone European network and the simulation results including network capacity requirements and failure notification times for various cases are analyzed and discussed.
