Abstract

Input and output queueing two stage ATM switch model which is effective under variable hot-spot traffic is proposed. In order to prevent the degradation of performance due to hot-spot traffic, the hot-spot route is added in which cells destined to the hot-spot port bypass. The switch applies the backpressure mode basically. When the switch judges that the hot-spot port exists, it routes cells destined there to the hot-spot route and applies the queue loss mode on them. We evaluate both the cell loss probability and the mean system delay under the nonuniform traffic with variable hot-spot port by computer simulation. As the results, it is shown that our proposed switch can achieve better switching performance than those of conventional switches under variable traffic condition.
