ATM network switch with congestion level signaling for controlling cell buffers

摘要: An ATM network switch is provided with a fabric linking plurality of slot controllers. Each controller receives cells from an external data link and has at least one input port to the fabric. The switches cell received any or more other ports. separate group buffers for each in switch, stores intended those buffers. includes buffer class traffic, so that are stored by class. also control circuit which controls passing FIFOs, indication fullness measured signaled back circuit. In response feedback signal congestion level switching path through thereto another, output switch.
