Analysis of p-cycle Capacity in WDM Networks
Tóm tắt
The concept of p-cycles provides many characteristics, which are benficial for deployment and operation in WDM networks. We present a detailed analysis of the resource efficiency addressing several issues, which are essential to WDM networks. This includes novel investigations about the influence of the length of working paths and a detailed redundancy comparison of p-cycles with prevalent protection mechanisms. In addition, we find several trends in the optimal p-cycle network design. One is the capacity smoothing effect that can be related to analytical capacity bounds. We can also identify that shorter p-cycles can facilitate optimal design in demand hot-spot regions. Finally, we propose a novel concept of p-paths, which, when used additionally in a p-cycle design, is able to improve capacity efficieny. This concept is also interesting in terms of both theoretical bounding conditions and practical deployment.
