Abstract
Methods and systems for performing rate limiting are provided. According to one embodiment, information is maintained regarding a set of virtual networks into which a network has been logically divided. Each virtual network comprises a loop-free switching path, reverse path learning network and provides a path through the network between a first and second component thereby collectively providing multiple paths between the first and second components. Packets are received by the first component that are associated with a flow sent by a source component. The packets are forwarded by the first component to the second component along a particular path defined by the set of virtual networks. A congestion metric is determined for the particular path and based thereon it is determined whether a congestion threshold has been reached. Responsive to an affirmative determination, the source component is instructed to limit the rate at which the packets are sent.
