A method and apparatus for routing packets through a multiport switch involves attaching indicators to packets before the packets are passed through a switch fabric, and then using the indicators to look-up output port vectors after the packets have been passed through the switch fabric. In a preferred embodiment of a 64.times.64 port switch, an 8-bit output channel vector and a 15-bit output port index are attached to a packet and passed through the switch fabric. The 8-bit output channel vector directs the packet to the proper output packet processor(s) and the 15-bit output port index is used to look-up an output port vector that identifies the output port(s) that will receive the packet. The method and system provide low packet overhead and flexible scaling.

An input-buffered multipoint switch having input channels and output channels includes multi-level request buffers, a data path multiplexer, and a scheduler. The switch has a distinct multi-level request buffer associated with each input channel and each request buffer has multiple request registers for storing data cell transfer requests of different priorities. The multi-level request registers are linked in parallel to the scheduler to allow arbitration among requests of different input channels and different priority levels. The preferred arbitration process involves generating masks that reflect the output channels required by the same priority level requests. Utilizing masks to arbitrate between multiple requests in an input-buffered switch reduces arbitration cycle time and minimizes HOL blocking.
