Evaluate the blocking performance for “all optical wavelength routed WDM networks with and without wavelength converters” using the iterative path decomposition algorithm

Wavelength-routed networks can effectively utilize the bandwidth of the optical fibers. Wavelength converters help to reduce the blocking probability of the network and enhance the fiber utilization. We use the iterative path decomposition algorithm to evaluate accurately and efficiently the blocking performance of 14-node NSFNet with and without wavelength converters. The iterative algorithm analyzes the original network by decomposing it into single-path subsystems. These subsystems are analyzed in isolation, and the individual results are appropriately combined to obtain a solution for the overall network.
