Abstract
A multiport network device includes a multiplicity of receive queues, a multiplicity of transmit queues and a forwarding engine for transferring entries from the receive queues to the transmit queues. When a transmit queue is greater than a first hysteresis point, the forwarding engine prevents transfer of entries from a receive queue to the transmit queue and transfer of entries to the transmit queue is allowed when the length of the transmit queue falls below a second hysteresis point.
