Performance comparison between recirculating loop buffer-based optical packet switch architectures


Due to the high cabling complications and limited scalability, the Ethernet switching is not a well-suited technology for the next-generation data center systems (NGDCs). In designing of interconnects for NGDCs, the first step is to select an appropriate switching technology. The best solution to the problems faced by NGDCs is the use of optical switching technology in the core of data centers. In this paper, three recirculating loop buffer-based optical packet switches are discussed. The first two switch discussed in this paper were proposed in the recent past, and the third switch is proposed by the authors of this paper. In this paper, a performance comparison between the switches is performed by considering physical and network layer parameters. The obtained results presented in the paper show that the performance of our proposed switch is better in comparison with other switches.
