摘要： A multi-channel packet switching apparatus having traffic flow controlling and checking functions which is capable of simply controlling the system and having a simpler construction by concurrently performing a cell copy function and a cell routing function for providing a multi-casting function. The apparatus includes a synchronizing unit for synchronizing the cells recirculated through the recirculation link with the cells newly inputted into the routing unit based on time and providing to the routing unit, a reverse direction flow control requesting unit for counting the number of cells which are recirculated at every cell time and requesting a reverse direction flow control to a traffic providing source when the thusly counted number exceeds a threshold value, a reverse direction buffering control unit for restricting a cell output to the output port through which a request signal is outputted when a reverse direction flow control request signal is received from the traffic receiving source until the request signal is released, an error cell removing unit for removing an error cell based on the routing tag error among the cells from the bypass link by the routing unit within a predetermined time, and a cell loss counting unit for counting the cell loss which are not recirculated by the recirculation path setting unit by the input port.

摘要： 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.
