Adaptive Ethernet flow control systems and methods

摘要

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.

1. A network element implemented method, comprising:
receiving an Ethernet connection at a first rate; transmitting the Ethernet connection at a second rate in a container; 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 comprise a determined optimal pause quanta value based on the first rate, the second rate, Ethernet frame size, and the buffer fill; wherein the first rate is associated with a rate of the Ethernet connection, and wherein the second rate is associated with a rate of the container, wherein the periodically transmitting pause frames comprises, if buffer fill is in a first region, periodically transmitting pause frames with the determined optimal pause quanta value comprising a first value, Q(g), and, if buffer fill is in a second region, periodically transmitting ause frames with the determined optimal pause quanta value comprising a second value, r and wherein the first value, Q(g), is determined based on a small frame size for the Ethernet connection and the second value, Q(r), is determined based on a large frame size for the Ethernet connection.
