Quasi-Shared Buffering Type Multicast ATM Switch Module Architecture with Two QoS Classes

摘要

The present invention relates to a semi-shared buffered multicast ATM switch structure which supports two QoS (quality of service) classes.; In the present invention, by dividing the buffer into two groups one buffer group store the cells belonging to real-time traffic class and the other one of the buffer group after storing the cells belonging to the non-real-time traffic class, the switching order of the two classes cells stored in a properly adjusted two buffers group separately, depending on the class of the selector to separate or non-real-time traffic if the input cell is real-time traffic in and switch elements to facilitate support of QoS couple of input cells required in each class and as management and for switching it, by managing to separate the two kinds of traffic that the traffic characteristics contradictory to reduce the latency for real-time traffic by reducing the cell loss for a non-real-time traffic is proposed a structure for improving the performance of the switch.
