Abstract:
1. A congestion management method, comprising: detecting network congestion at a first congestion point of a network; identifying a first congested entity of the network; calculating feedback information specifying a current queue level of the congested entity; sampling a first frame received from a first reaction point; sending a first feedback message to the first reaction point of the network, the reaction point being associated with one or more traffic flows causing the congestion, at least in part, the feedback message including the feedback information and identity data for the congested entity; sampling a second frame received from the reaction point; determining whether the second sampled frame includes responsive data that identifies the first congestion point in response to the first feedback message; and sending a second feedback message to a source of the second sampled frame according to a result of the determining step, wherein the second feedback message is sent at least in part according to whether the second sampled frame includes responsive data that identifies the first congestion point in response to the first feedback message.
