Minimum Wavelength for Optimal Waveband in WDM Network Using Mesh Topology

ABSTRACT: An optical cross-connect can be achieved by grouping together a set of consecutive wavelengths and switching them as a single waveband. This technique is known as waveband switching. This paper focus on the number of wavebands and their sizes for ring topologies. It presents a novel framework for optimizing the number of wavebands in a ring network for deterministic traffic.The objective of the Band Minimization Problem is to minimize the number of non uniform wavebands in the network while using the minimum possible number of wavelengths. I have considered a specific type of traffic, namely all-to-all traffic, and present a construction method for achieving the minimum number of wavebands in the ring. The results show that the number of ports can be reduced by a large amount using waveband switching compared to wavelength switching, for both all-to-all traffic and random traffic. And also numerically evaluate the performance of our waveband design algorithms under dynamic stochastic traffic.
