Adaptive-Cost Shortest Path Based Heuristic for Space Division Multiplexing Networks

The total Internet traffic is rapidly rising as a result of the growing popularity of various network services. One of the network types is mesh network where space division multiplexing (SDM) has become an interesting approach to deal with the upcoming capacity crisis issue. SDM's key concept is to take advantage of the spatial dimension to significantly increase transmission system power. In this paper, we present an adaptive cost shortest path based heuristic for flexgrid SDM optical networks. The preliminary experimental results show a promising performance in terms of minimizing the highest used number of slices over all the links/cores of the network.
