Elastic Rerouting - models and resolution methods

Abstract

This study is concerned with an original traffic restoration strategy for wide-area communication networks called Elastic Rerouting (ER). ER aims at alleviating the tradeoff between the network cost and traffic restoration complexity observed in existing solutions. We present the strategy, provide a mathematical formulation for the ER related optimization problem, and discuss an approach to its resolution.We also report results of a numerical illustrating effectiveness of ER in terms of the link capacity cost.
