Performance Evaluation of a Modified Cyclic Banyan based ATM Switch for B-ISDN

This paper focuses on designing a Fast Packet ATM switch suitable for B-ISDN. It is a Banyan network using cyclic interconnection among switching elements of the same stage for deflection routing. The proposed routing is as simple as that of the generic Banyan network, and all the switching elements (SE’s) have a uniform structure. To design the proposed network and to develop its self-routing property we observe that all the SE’s of the Banyan network are arranged in a regular pattern topologically. We, thus, present a highperformance switching fabric based on the topological properties of Banyan Networks. As a result, we show that the new network has a better performance than other networks.
