Performance of distributed reservation control in wavelength-routed all-optical WDM networks with Adaptive Alternate Routing

In this work, we consider the performance benefits of distribution reservation control schemes in partially-connected wavelength-routed all-optical WDM networks. In particular, we propose a new distributed reservation control scheme designed to work for general topology wavelength-routed WDM networks. In this new scheme, capacity reservation is invoked by always using the first shortest path if the direct route does not exist between all node (demand) pairs. Through our study, we show that our proposed scheme in the presence of distributed adaptive routing is much more fair on pairwise blocking than the conventional reservation method in general topology wavelength-routed WDM networks, especially in the presence of wavelength converters and overload situations.
