Patent ID: 7961605

Claim:
A method of enabling management of a plurality of messages in a communication network, the method comprising: transmitting a plurality of messages from a source-node to a plurality of destination-nodes through a plurality of switching nodes of a communication network; measuring an in-load and an out-service corresponding to a plurality of switching-nodes in the communication network, wherein an in-load of a given one of the switching-nodes is a rate of injection of messages in at least one input-port of the given switching-node, an out-service of the given switching-node is a rate of egress of messages from at least one output-port of the given switching-node, wherein an input-port corresponds to an output-port; marking at least one message in the given switching-node with an Explicit Congestion Notification (ECN) to form at least one Precise ECN (PECN)-message, if at least one predefined criterion corresponding to the given switching-node evaluates to true, wherein each PECN-message is encoded with measurements of the in-load and the out-service corresponding to the given switching-node, wherein the at least one PECN-message includes an Absolute PECN (APECN)-message, and the APECN-message is encoded with absolute value of each of the in-load or the out-service of the given switching-node, wherein the switching-node generates the at least one PECN-message; and performing at least one management function to modify egress of the plurality of messages from the source-node, wherein the at least one management function is performed based on the measurements of the in-load and the out-service encoded in each PECN-message, the at least one PECN-message includes a Weighted-PECN (WPECN)-message, the WPECN-message is encoded with weighted-feedback-values corresponding to the measurements of the in-load and the out-service of the given switching-node, wherein the given switching-node generates the at least one PECN-message, wherein the weighted-feedback-values comprise at least one of: a Hot Spot Severity (HSV)-factor, wherein the HSV-factor corresponds to ratio of the in-load to the out-service of the given switching-node corresponding to the WPECN-message; a first derivative of the HSV-factor, wherein the first derivative of the HSV-factor corresponds to the speed of increase of the HSV of the given switching-node; and a second derivative of the HSV-factor, wherein the second derivative of the HSV-factor corresponds to rate of alteration in speed of increase of the HSV of the switching-node, wherein at least one of the first derivative of the HSV-factor and the second derivative of the HSV-factor predicts a lag in a feedback-loop in the communication network.
