QoS WDM Network Architecture Design and Simulation

Abstract

A usual infrastructure above which a diversity of services are able be to conveyed is given by an optical network. This optical network is also efficient of delivering bandwidth in a pliable way, transparency within data transference and capacity of gradation is also handled by these networks. It comprises of transmitter and transmission medium in which optical source (LASER, LED) works like a transmitter and optical fiber like transmission medium, accompanied by photo detector and connectors, receiver set. By using a single high capacity channel or wavelength it is difficult to utilize all the BW of an optical fiber because of restriction in electronic processing speed. Discovering best feasible path within a source and destination node pair and allocating accessible wavelength to this feasible path for data transference is the main difficulty in designing a WDM network. A sequence of measurements called as Performance Matrices are executed to decide the best path. The quality of service (QOS) parameter is decided with the help of performance matrices. In this we have designed 4 unlike network topologies in which each have same capacity but dissimilar number of nodes. For obtaining performance matrices we have simulated all the 4 networks with distinct frameworks, and contrasted these performance matrices for recommending finest network under the present case.
