Nowadays the amount of Internet traffic in current backbone networks has grown enormously due to wide deployment of broad-band Internet access and new multimedia applications such as sensing data sharing and real-time streaming. The processing speed of the electronic switching will become a bottleneck for the next generation optical networks. Therefore, optical packet switching (OPS) is a long-term strategy for network evolution that exploits fast switching techniques to provide greater bandwidth efficiency, flexibility, functionality, and offer finer granularity. The main objective of the project presented in this report is to research and develop optical packet switching systems with multicast and multi-wavelength capability. In this report, the optical packet switch architecture with different multicast and multi-wavelength modules are proposed and investigated. Discussion includes the theory behind optical packet switching and the implementation of the technologies. Furthermore, a packet scheduling is developed for cooperating with the proposed optical packet switches. The traffic performances in terms of packet loss probability, average delay of the proposed switch are evaluated and compared by computer simulations under a hybrid traffic model. The simulation results shows that the proposed optical multicast packet switches can achieve a low packet loss probability in conjunction with the packet scheduling algorithm.
