Abstract
A switch applies back pressure to an ingress port while an output queue is congested. The switch includes an output queue associated with an egress port in the switch. The output queue stores packet pointers to data to be transmitted to the egress port. A back pressure controller in the switch applies back pressure to an ingress port while the output queue is congested upon receiving data at the ingress port to be transmitted to the egress port.
