Multicast Packet Switch Based on Dilated Network

概要

Multicasting is an important feature for any switching network being intended to support broadband integrated services digital networks(B-ISDN). This paper proposes an improved multicast packet switch based on Lee's nonblocking copy network[1]. The improved design retatins the desirable features of Lee's netowork including its nonblocking property while adopting techniques to overcome the various limitations mentioned in various literature. The proposed network architecture utilizes d-dilated banyan networks to increase the amount of cells that can be replicated within the copy network. Cell splitting is used to optimize the utilization of the network's available bandwidth. Furthermore, the proposed architecture allows for the modular expansion in capacity to accommodate changing traffic patterns. The mondular design of the proposed switch likewise offers easy handling and replacement of faulty modules.
