Abstract
A data frame is received at a network switch, the data frame containing congestion status information for at least a first traffic class and a second traffic class associated with packets being transmitted by the network switch to a network interface device. When the network switch determines, in response to the data frame containing congestion status information, that the congestion status information indicates congestion corresponding to the first traffic class, the network switch reduces a rate of transmission of packets (i) corresponding to the first traffic class and (ii) destined for the network interface device.
