An optical switch is designed and its faut-tolerance/survivability performance is presented in this seminar. The performance is carried out and compared with two major fault-tolerant networks, Itoh's and Benes'. The results show that without redundant switches, better network survivability is achieved. In addition, much less hardware is needed. The preliminary results of the analysis show that the proposed switch has comparable performance to other fault-tolerant networks whereas it outperforms them in other aspects such as number of extra switches/links, thus providing better cost-effectiveness.
