Optimal Virtual Topology Design using Bus-Label Switched Paths
— Although there is a trend in reducing the number of layers in core and metropolitan area networks, still the optimal design of multi-layer networks (like IP over WDM) remains an important issue as a means to reduce CAPEX and OPEX. In multi-layer networks, usually a connection oriented network (like WDM) is used to deploy a layout for the optimal transport of the traffic. In present GMPLS networks, the layouts are based on point to point LSPs. We will show here that by using the novel bus-LSPs, we can achieve some significant savings for the operator, both in terms of CAPEX and OPEX. We also introduce a heuristic algorithm to design optimal layouts, and provide a quantitative evaluation of it.
