A model to allow remote and distributed simulation of optical networks using XML

This paper proposes a model and a tool to allow remote and distributed simulation of optical networks using XML. We define how the simulation can be parallelized in order to be quickly processed. We use remote access in order to perform the simulations in multiple processors simultaneously by sending the network and the simulation description coded in XML to the available remote computers. The sequential and distributed simulations modes were compared in two different situations in order to show that we can successfully perform parallel processing in the simulation of optical networks. We achieved a speedup of 7 in a remote simulation running in two Quadcore processors when compared to the previous version of our simulator, which runs in a single core processor.
