Abstract:
A packet switching apparatus, comprising:output group address generation means for providing an address information for each one of a plurality of individual output ports in a grouped output port;routing means for receiving input cells comprising recirculated cells, which have been recirculated through a recirculation path, and newly inputted cells, each of said cells having a routing tag including a destination address data;said routing means further comprising means for comparing said destination address data for each of said input cells to said address information output by said output group address generation means and assigning an output link to selected ones of said input cells when said destination address data is identical to said address information, with preference given to recirculated cells, and outputting others of said input cells, which were not assigned said output link, through a plurality of bypass links;said output links corresponding to said individual output ports;recirculation path setting means for selecting an R-number of said others of said input cells from said bypass links and outputting said R-number of cells through said recirculation path, wherein said R-number comprises a number of cells which can be simultaneously transmitted through said recirculation path; andsynchronization means for receiving said R-number of cells on said recirculation path, time-synchronizing said R-number of cells with a new group of newly input cells and outputting R-number of cells as said recirculated cells to said routing means.
