Network-resource deployment considering both resource amount and operation-risk reductions

Abstract

Physical-network-resource deployment to meet future traffic growth is a significant issue for network operators because it is related to the ground design of next generation networks. In this paper, we propose an effective heuristic decomposition method of physical-network-resource deployment considering the balance between the amount of additional network resources Q and operation-risk. We focus on decreasing the number of physical links with additional capacity Nu to reduce operation-risk. Numerical evaluations indicate that, with our method, pareto-optimal solutions between Q and Nu can be designed with a smaller Nu, more than 50% smaller, compared with a benchmark method that minimizes Q.
