Abstract
An improved packet switching apparatus with multichannel and multi-cast switching functions and a packet switching system using the same which are capable of more simplifying the routing of an internal routing during the integration of the switching apparatus by using a simpler 2.times.2 switch device for a concentration network in order to provide a routing network and a recirculation path and by using a pattern connection characteristic consisting of a column and row. The apparatus includes an output group address generator for providing an address information of an output port grouped, a routing unit for receiving a cell which is recirculated through a recirculation path and a newly inputted cell, assigning an output link with respect to the recirculated cell when an output port-dependent address inputted from the output group address generator and a destination address set in a routing tag of a cell inputted by the port are identical, and outputting the cells which was not assigned of the output link through a plurality of bypass links, a recirculation path setting unit for selecting a cell as many as the number of circulation paths among cells outputted from the routing unit t…
