Abstract

ATM has been proposed as the technique that will support B-ISDN services of the future. Thus the high-speed fabrics that switch the fixed-size ATM cells at switching nodes in the network, need to have efficient buffer management schemes to control size and therefore cost of buffers. Most of the buffer management schemes proposed to date do not perform well under non-uniform traffic. But it is well accepted by now that future ATM traffic is very likely to be non-uniform, although the nature of the non-uniformity is likely to vary over time. Each of the buffer management schemes proposed for the non-uniform case, performs better than the other for some values of the traffic parameters. In this paper we have proposed a new buffer-management scheme, called Hot-Spot-Push-Out (HSPO) which performs uniformly better than all the previously proposed schemes under bursty traffic. This is demonstrated by simulation.
