Abstract
A network element implemented method includes receiving an Ethernet connection at a first rate, transmitting the Ethernet connection at a second rate, monitoring a buffer fill associated with the Ethernet connection, and periodically transmitting pause frames to a device associated with the Ethernet connection, wherein the pause frames include a determined optimal pause quanta value based on the first rate, the second rate, and the buffer fill. A network element includes a first port receiving an Ethernet connection at a first rate, a second port transmitting the Ethernet connection at a second rate, and monitor circuitry configured to monitor a buffer fill associated with the Ethernet connection and cause the first port to periodically transmit pause frames, wherein the pause frames include a determined optimal pause quanta value based on the first rate, the second rate, and the buffer fill.
