Abstract:
1. A method for executing flow control of data having a plurality of priority classes between a receiving end device and a transmitting end device, comprising: monitoring an input buffer to determine whether an available space in the input buffer is less than a threshold, wherein the input buffer is disposed in the receiving end device and stores therein the data from the transmitting end device; transmitting an extended pause frame having a MAC control code field and a stop time period field to the transmitting end device in the receiving end device upon determining that the available space in the input buffer is less than the threshold, wherein an identifier indicating the extended pause frame is set in the MAC control code field, and a ratio of the available space in the input buffer to a total capacity of the input buffer is set in the stop time period field based on the available space in the input buffer; and reducing, using a processor, a band for all the priority classes based on the ratio in the stop time period field of the extended pause frame in the transmitting end device.
