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 network device thereby collectively providing multiple paths between the first and second network devices. Packets are received by the first device that are associated with a flow sent by a source network device. The packets are forwarded by the first device to the second device via a particular path of the multiple paths. 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 device is instructed to reduce the rate at which the packets are sent.
