Asynchronous expansible switching system for switching packet with different length

摘要

An asynchronous expansible switching system for switching packet with different length mainly comprising a plurality of linecards, preprocessors, sequencers, switching planes and multiplexers and is able to provide an optional routing mechanism for a distributed packet, wherein the switch is able to expand the switching plane in accordance with the increase of the input port and the output port and transmit the packets within the buffering of the output port of the switching plane to the output port by the control of the preprocessor and the sequencer.
