Abstract
The end-to-end performance for circuit switched all-optical networks in multi-fiber multi-hop environments is modeled and evaluated with and without wavelength conversion. We study the effects of parameters such as path length, number of fibers, number of wavelengths in each fiber, and offered load on key performance parameters in multi-fiber multi-hop setting. The increase in performance in the wavelength routing DWDM network due to wavelength conversion at each node, and different degrees of wavelength conversion are considered. This work also examines different wavelength converter sharing architectures and their effects on performance when the hops along the path between source-distention pair have different loads. It also examines the performance issues for share-per-link wavelength convertible switch (WCS) using a simple Conversion Resources Allocation Algorithm (CRAA).
