Abstract
In one embodiment, a method includes receiving, using a controller, a congestion notification message from a first virtual switch of a first server indicating that a first virtual machine (VM) hosted by the first server is overloaded, and advertising, using the controller, a congestion status of the first VM to one or more virtual switches in a network using a congestion status message in response to receiving the congestion notification message. In another embodiment, a method includes receiving, using a first virtual switch of a first server, a congestion status message from a controller indicating that a second VM hosted by a second server is overloaded, and stopping traffic that is destined for the second VM from being sent in response to receiving the congestion status message from the controller without restricting sending traffic that is destined for other VMs hosted by the second server.
