ACTIVE OUTPUT BUFFER CONTROLLER FOR CONTROLLING PACKET DATA OUTPUT OF MAIN BUFFER IN NETWORK DEVICE AND RELATED METHOD

摘要

An active output buffer controller is used for controlling a packet data output of a main buffer in a network device. The active output buffer controller has a credit evaluation circuit and a control logic. The credit evaluation circuit estimates a credit value based on at least one of an ingress data reception status of the network device and an egress data transmission status of the network device. The control logic compares the credit value with a first predetermined threshold value to generate a comparison result, and controls the packet data output of the main buffer according to at least the comparison result.
