Abstract:

To obtain peer to peer (P2P) flow information accurately in a realtime and lowcost way, NetFlow based P2P flows analysis system called netFlowbased P2P flows analysis system(NPFAS) is proposed, it loosely integrates systems for flow aggregation, flow identification and flow analysis respectively in a distributed manner. By utilizing the key information of P2P flows provided by P2P identification systems, NPFAS can extract P2P flow statistical information from NetFlow records generated by NetFlowenabled devices and analyze it by some existing analysis systems. NPFAS provides a feasible solution for analyzing P2P flows based on the LinuxIntel framework. Experiments of the prototype system have verified feasibility and availability of NPFAS.

Key words: peer to peer, distributed architecture, NetFlow, analysis system
