Analytical modeling of multicast-pushout in shared-memory ATM switches
J.D. Ho, Samar Singh, Neeraj Sharma · 2002
We present an analytical model for a multicast-pushout write policy. The pushout scheme maintains a high switch throughput by providing an optimum balance of unicast and multicast cells in the buffer. The scheme is adaptive to changes in multicast traffic such as changing fanout sizes and input rates. We demonstrate that the model is accurate for various loads, ratios of multicast traffic and fanout sizes.
