Patent attributes
A method for alleviating flow congestion at forwarding elements is provided. The method receives traffic related data from a plurality of forwarding elements of a network, and based on the traffic related data, determines congestion at a first forwarding element of the plurality of forwarding elements caused by at least one flow passing through the first forwarding element at a first rate. The method calculates, based on a burst size of the at least one flow, a second rate for the at least one flow such that when the at least one flow passes through the first forwarding element at the second rate the congestion at the first forwarding element is alleviated. The method rate limits the at least one flow by passing the at least one flow through a flow rate manager at the calculated second rate before transmitting the at least one flow to the first forwarding element.
