Paper Abstract

In this paper, we proposed a novel architecture of MG-OXC (Multi-Granularity Optical Cross Connect) that can support both the static and dynamic optical switching. It can obviously reduce the complexity of the switching matrix and the number of the switching ports without increasing the network blocking probability. We gave the ILP model to describe the multi-granularity switching optical network. This model is applicable not only to the novel MG-OXC, but also to the traditional MG-OXC network. We also proposed a novel routing and wavelength assignment algorithm for dealing with multi-granularity traffic in optical network that was set up by this kind of novel MG-OXC. It is shown that when the network load is low, the network blocking probability of the novel MG-OXC will be quite lower than the ordinary multi-layer and single-layer MG-OXC with the strategy of the shortest wavelength path and random choice of the wavelength. While when the network load is comparatively higher, the network blocking probabilities of these structures are more or less the same.
