Paper Abstract

This paper studies the use of wavelength translation in different Clear Channel setup strategies in a scalable all-optical network. the network considered used a recursive grid architecture representing the 100 largest cities and constituting 561 access stations. As the network grows, the grid is subdivided in a recursive fashion to accommodate more nodes, making the network modular. The algorithm used for routing of the calls is distributed, dynamic, and scalable in the sense that the complexity of the algorithm grows slower than linear with the network size. The performance of wavelength translation with static and dynamic routing strategies is studied using simulation in terms of the blocking of incoming requests for Clear Channels. Optical wavelength translation is provided in the network and it is shown that for the network considered, the improvement in performance is marginal. The Clear Channel blocking, with and without wavelength translation, is studied for different traffic patterns ranging from fully uniform traffic to a pattern exhibiting very strong communities of interest. The impact of wavelength translation is considered for these different traffic patters. The Clear Channel setup strategies along with the architecture are all scalable and hence are applicable to very large networks.
