Scheduling Strategies for Network Link Upgradation with Ultra Low Loss Fibers

Abstract

The lifespan of a fiber cable is limited to about 20~25 years, so now it is time for many networks to consider the issue of link upgradation with new-generation fibers, e.g., ultra-low loss (ULL) fibers. In this paper, a path-arc based ILP model and three scheduling strategies for fiber link upgradation are developed. Results demonstrate the efficiency of the proposed strategies.
