Survivable Network Capacity Allocation and Topology Design Using Multi-period Network Augmentation

摘要

This paper examines the effect of incorporating multi-period network augmentation into the survivable network design process. The framework presented can handle variable restorability requirements, potential economies of scale, and technology shifts. By utilizing a multi-period planning model, shifts and uncertainties in demand and policy can be accounted for. This study examined the design of survivable networks using both demand-wise shared protection and shared backup path protection (representing opposite ends of the mesh network efficiency spectrum) with topology augmentation over multiple time horizons.
