A power-efficient design scheme for survivable networks with partial bandwidth path protection

Abstract

This letter proposes a design scheme for the powerefficient network with partial bandwidth path protection. The network with the proposed scheme utilizes resources efficiently, which leads to less power consumption. This scheme employs a Linear Programming (LP) approach to minimize power consumption by considering the number of active devices and capacity consumption. Simulations show that, with the partial bandwidth path protection, the proposed scheme saves more power than the conventional scheme, which minimizes the power consumption relying on capacity consumption.
