Design and analysis of an intelligent multicasting routing in all-optical networks with fault tolerance mechanism

In this paper we design and analysis an intelligent multicasting routing algorithm on a wavelength routed WDM network based on the multicasting and fault-tolerant optical crossconnect (MFOXC) architectures. The performance of the proposed algorithm is evaluated in terms of the average maximum number of wavelengths (W), the average bandwidth (B), and the average delay (H). The simulation results show that: a) the splitting capability can improve the network performance in terms of delay, wavelength, and bandwidth; b) The wavelength conversion capability does not have an effect on the performance parameters as significant as the splitting capability; c) The fault tolerance capability can improve the network delay. All these scenarios meet our design strategy for an intelligent MFOXC network. Hence it is crucial to use MFOXC at critical points in a network to improve the reliability and multicast performance.
