Abstract

In the physical topology design, the number of OXCs and/or links is takes as the objective. In this paper, we take aim at minimizing the maximal optical port number of each OXC, given the number of OXCs and the traffic. We present a traffic-oriented heuristic algorithm to generate an initial topology. This presented algorithm outperforms the previous algorithm, since our presented algorithm takes into account the traffic pattern. Furthermore, we present a routing strategy that is a balance between the shortest-path routing and the least-congestion routing. The tabu algorithm is adopted to attain the optimal solution. We choose the path-based sharing protection scheme to provide 100% recovery guarantee. Numerical results demonstrate the effectiveness of our algorithm and strategy.
