“…To be able to accommodate multicast traffic, ATM switches must provide a mechanism to replicate multicast cells [2]. The two commonly used schemes in replicating multicast cells are the Replication-At-Receiving (RAR) and the Replication-At-Sending (RAS) schemes [3].…”

A major finetion of a multicast switch that can determine its performance is the replication of multicast cells. Replicating multicast cells upon arrival provides the switch a high throughput performance. However, it also produces a redundant payload that increases the cell loss probability. Generating all the copies of a multicast cell when it is to be transmitted to the output can achieve a low cell loss probability at a cost of a low throughput performance. The input-indexed switch has an architecture that can obtain a high throughput performance and a low cell loss probability. It physically replicates multicast cells at transmission, yet has the structure that can logically replicate them upon arrival without generating redundant payload information. The multicast input-indexed scheme is an input-queued switch that has a distributed contention resolution using token bus arbitration. This paper evaluates its performance using computer simulation under different multicast proportions at 100% offered load.

“…Sevcral cell replication schemcs havc becn proposcd in thc literature, which can be roughly classified into three categories : (1) cell replication before routing [I, 2, 31, (2) cell replication while routing [4,5] and (3) cell recycling [6,71. It is likely that switchcs with various architectures will choosc different schemcs or a combination to implement multicast function [13].…”

A (large) multicast ATM switch with external structure of output queueing and internal structure of buffered MINs (multistage interconnection networks) is considered, where the buffered ,WIN (also called switching network) is composed of switching elements with shared buffer output queueing. Cell replication while routing schemc is used in the switch to implement multicast function. In this paper, we study the performance of the switch with multicast traffic, mainly via computer simulations. The multicast traffic can be random and bursty. From our study we found that for multicast traffic with truncated geometric dastribution of cell fanouts it has only a slightly worse impact on the performance of switching clemcnts in isolation or in the last stage of the switching network. The multicast trafic has no worse effect on the switch output buffer behavior and cell delay in the switching network. Moreover, trafic splitting can substantially improve the switching network performance f o r highly bursty trafic. Some analytical approximations are givcn which could bc useful in the dimensioning of switching networks.
