Fixed-length packet switching device using multiplexer and demultiplexer

摘要

The present invention relates to a fixed-length packet switching apparatus using a multiplexer and a demultiplexer having a flow control structure with respect to each other in order to protect a switching device from a temporary overflow of an output terminal and improve overall performance, It is possible to protect the entire operation of the switching device and improve the overall performance by preventing the switching device from being disturbed due to the overflow that occurs temporarily at the output terminal, It is possible to perform processing without excessive cell loss. In addition, according to the speed gain effect, it is possible to smoothly process not only the reduction effect of the required buffer but also the case where the input traffic to the internal buffer has burst characteristics. In addition, since it has a function of replicating cells so as to provide broadcast-type services simultaneously distributed to a plurality of subscribers, the efficiency of channels can be improved because a plurality of subscribers can receive distribution services.
