System and method for policing multiple data flows and multi-protocol data flows
View Patent ↗A system and method for policing one or more flows of a data stream of packets associated with differing transmission protocols. The current capacity level for each flow is determined, as is the packet protocol associated with each packet. A packet parameter in the packet that is indicative of the bandwidth consumption of the packet is identified. The packet parameter is converted to a predetermined format if the packet is not associated with a predetermined packet protocol. A common bandwidth capacity test is performed to determine whether the packet is conforming or non-conforming, and is a function of the packet parameter and the current bandwidth capacity level.
1. A method of forwarding packets using processing circuitry comprising:
classifying a packet from a plurality of packet protocols according to a classification, wherein the classification is determined from at least one parameter indicative of the bandwidth consumption of the packet;
if the packet is not classified as one of a plurality of predetermined protocols, converting the packet parameter into a predetermined format such that a bandwidth capacity test can be utilized;
performing the bandwidth capacity test based on the packet parameter; storing in a switch fabric of a communication network the packet in one of a plurality of flows corresponding to the classification, wherein
each flow corresponds to one of a plurality of flow defining criteria associated with the classification;
assigning a priority to said plurality of flows based on a result of the bandwidth capacity test; and
forwarding the packet from said flow according to said priority.
2. The method of claim 1 , wherein said plurality of packets is dynamically classified according to said plurality of flow-defining criteria.
3. The method of claim 1 , wherein said plurality of packets is dynamically classified according to a plurality of predefined packet parameters.
4. The method of claim 1 wherein said flow-defining criteria is associated with a packet transmittal rate.
5. The method of claim 1 wherein said at least one packet parameter comprises a sender address.
6. The method of claim 1 wherein said at least one packet parameter comprises a receiver address.
