Patent ID: 7821939

Claim:
A method for adaptive congestion control in a Data Center Ethernet (DCE) network, comprising: receiving packets at a receive buffer over at least one virtual lane in the DCE network; computing an absolute or a relative packet arrival rate over a time period; adjusting the receive buffer size in response to computing the absolute or relative packet arrival rate; comparing the absolute or relative packet arrival rate to at least a first threshold, a second threshold and a third threshold; issuing a command to decrease the packet transmission rate in response to determining that the absolute or relative packet arrival rate exceeds the first threshold; and issuing a command to increase the packet transmission rate in response to determining that the absolute or relative packet arrival rate is less than the second threshold; and issuing a command to decrease the packet transmission rate after waiting a period of time in response to determining that the absolute or relative packet arrival rate exceeds the third threshold but is less than the first threshold.
