An effect multicast ATM switch for advanced multimedia communication: SSMAP (singlecast stuffed multicast advanced processing) ATM switch

摘要

In the various communications services that require information to be delivered from a source to multiple destinations, effective multicast ATM switches are an essential component in providing multicast communications capability. In this paper, we present a new multicast ATM switch, called SSMAP ATM switch, which can transmit multicast traffic effectively. SSMAP ATM switch consists of two cell operation parts, multicast operation part and singlecast operation part. This structure improves the performance of the switch considerably. Further, we propose new multicast scheduling methods using SSMAP ATM switch. We evaluate the characteristics of SSMAP ATM switch and multicast scheduling methods by computer simulations, and show their validity numerically.
