In this paper, we present three heuristics for mitigating post-disaster traffic floods. First exploiting the excess capacity, second rerouting backup paths, finally redistributing the whole traffic by rerouting the working and protection paths to accommodate more floods. Using these mitigation approaches can reduce the blocking by up to 30%.
The increasing number of disasters around the world calls for a new direction in building the networks; this direction is known as disaster-resilient networks. In this paper, we consider the effect of post-disaster traffic on the core network performance. We evaluate the network blocking during single node flooding with different flood sizes. Then we study four mitigation approaches to maximally serve...
In this paper, we investigate the energy efficiency that can be achieved by using traffic scheduling in IP over WDM networks. A mixed integer linear programming model is developed to optimize routing and scheduling in dynamically arriving demands, where part of the demands can be allocated within a sliding window. The results show that scheduling improves the energy efficiency of non-bypass IP/WDM...
