A high performance ATM switch based on the augmented composite banyan network

In this paper, we propose a new high performance ATM switch architecture based on a high connectivity multipath multistage interconnection network called augmented composite banyan network (ACBN). The ACBN is created by adding a link to each switching element of the composite banyan network, which is a multipath network with at least two disjoint paths and was originally proposed in Seo and Feng (1995). The switch performance is studied under uniform and full load conditions. The analysis and simulation results show that the proposed switch can achieve a required cell loss probability using fewer stages than previously reported switches
