Abstract:

With the growing traffic demands Mixed Line Rate (MLR) WDM (Wavelength Division Multiplexing) provides different bandwidths by using different modulation types. In this paper, a new simple routing algorithm is proposed by monitoring the dynamic traffic of a network using Poisson random traffic model .The proposed work can be achieved by finding the best possible shortest path between source and destination node and adjusting the number of light paths. Adjustments employ addition or deletion of light paths according to traffic load at any time. Simulation results demonstrate the total number of lightpaths used total number of addition/deletion of light paths and shows the comparison between single line rate (SLR) and mixed line rate (MLR).
