Cross-Layer Optimization and Cascadability of Optical Switches in Fiber Optic Data Networks

Abstract In the most recent years, developing web applications such as cloud computing, Big Data and latest cell phone applications have added more workload on the server centers. With the expansion on the network traffic, the consumption of power also increases. In past to reduce power consumption AWG based optical switch designs are proposed, and BER, energy consumption analysis has been carried out in isolated switch. In this paper, cascadability analysis of optical switches in fiber optic and data center networks is presented, and BER is calculated for isolated and cascaded switches. In fixing switch size concepts of graph theory and small world model are used. The packet loss performance is also simulated under different loading and buffering conditions. Finally, cross layer optimization concept is discussed in fixing various switch parameters.
