A method of performing congestion management in a network includes monitoring a congestion status at a switch in the network. It is determined at the switch that the congestion status indicates that there is congestion at the switch. Based on the congestion being related to data received at the switch from a source at a first rate, a first message is transmitted from the switch to the source requesting the source to send the data at a second rate that is slower than the first rate. Based on the congestion being related to data requests received at the switch from a destination at third rate, a second message is transmitted from the switch to the destination requesting the destination to request the data at a fourth rate slower than the third rate.
