MULTICASTING IN ATM NETWORKS USING MINS

In this paper, we discuss the problem of establishing multicast connec tions using self-routing multistage interconnection networks (MINs). W e examine the issue of multicasting and propose various schemes to acc omplish it. Multicasting using recycling of cells has been suggested i n the literature recently. We propose a multicast switch architecture that requires a few simple enhancements over a MIN and describe the pr ocess of setting up a multicast connection. The size of the routing ta bles limit the number of copies per cell that can be generated per pas s through the network. We assume that no more than two copies per cell can be generated per pass through the routing network, and provide de tailed cell-level simulation results for the average delay of a cell. The results show that recycling is a practicable option for multicasti ng and that the delay does not increase drastically when cells are rec ycled.
