Patent ID: 8085775

Claim:
A machine-implemented method for the identification and handling of a single application flow, the flow comprising a plurality of information packets, and the method comprising: creating a flow block as the first packet of a flow is processed by a router; said flow block being adapted to store payload-content agnostic behavioral statistics about said flow; updating said flow block with the flow's payload-content agnostic behavioral statistics as packets belonging to said flow are processed by said router; said flow being incapable of being identified by header information alone; heuristically determining whether at least one user-specified policy is satisfied by said payload-content agnostic behavioral statistics stored in said flow block; and upon determination that at least one user-specified policy is satisfied by said payload-content agnostic behavioral statistics, applying, to at least one packet belonging to said flow, at least one user-specified action that is mapped to the at least one user-specified policy that is satisfied by said payload-content agnostic behavioral statistics; wherein said payload-content agnostic behavioral statistics for said flow are calculated by said router; wherein said payload-content agnostic behavioral statistics reflect the empirical behavior of said flow; wherein at least one of said payload-content agnostic behavioral statistics is chosen from the group consisting of: total byte count accumulated for the flow, flow life duration, average rate of flow, average packet size, average packet rate, average inter-packet gap, instantaneous flow rate, and moving average flow rate.
