A New Architecture for Lightwave Networks

摘要

In this paper we propose a new architecture, Generalized Multi-Mesh, for wavelength division multiplexed optical networks. In terms of simplicity of interconnection and routing, this architecture is comparable to the torus network. However, the new architecture exhibits significantly superior topological properties than the torus. For example, whereas a two dimensional torus with N nodes has a diameter of Θ(N~(0.5)), a Multi-Mesh network with the same number of nodes and links has a diameter of Θ(N~(0.5)). The generalized Multi-Mesh network can be constructed for any number of nodes and is incrementally expandable. We provide results of our simulation studies for the call blocking probabilities of this network. The advantage of the Generalized Multi-Mesh over the de Bruijn network lies in the fact that, unlike the de Bruijn network, this network can be constructed for any number of nodes and is incrementally expandable.
