Packet Switching Device with Multichannel / Multicast Switching Function and Packet Switching System Using the Same

摘要

1. TECHNICAL FIELD OF THE INVENTION;Packet switching device having a multi-channel / multicast switching function and a packet switching system using the same.;2. The technical problem to be solved by the invention;The purpose of this study is to improve the cell processing capability of the switch by making the relationship between the input and output ports physically and logically many-to-many.;3. Summary of Solution to Invention;Means for providing the address information of the grouped output ports, and a plurality of recycled cells and newly input cells received from outside, and assigns an output link when the output group address and the destination address of the input cell are the same. Routing means for outputting cells not allocated to the output link through a plurality of bypass links, means for selecting as many recycle paths among cells input through the plurality of bypass links and outputting them through a recycle output link, and the recycling Means for synchronizing the recycled cells input through the output link to the routing means.;4. Important uses of the invention;Used in ATM switching devices and fixed-length packet switching devices.
