ABSTRACT:
The present invention relates to a fixed length packet switching apparatus using multiplexers and demultiplexers in which the apparatus has an output buffer-type construction, protects itself from a temporary overflow occurrence of an output terminal and has the construction of the mutual flow control to enhance its entire performance. The present invention can protect the entire operations as well as enhance the entire performance of the switching apparatus by preventing an obstacle of the switching apparatus due to an overflow temporarily generated from an output terminal, process without a loss of excessive cells a traffic phenomenon of one output port in the switching apparatus, reduce the necessary buffer according to the effect of the rate gain and process smoothly input traffic of the internal buffer having a burst characteristic. Further more, the present invention has a duplicate function of cells able to provide a broadcast-type service distributed to subscribers at one time so that the subscribers can receive a distributed service to thereby increase the effectiveness of the channel.
