Abstract: According to the deficiencies of current performance analysis tools, one network performance analysis model based on data mining is proposed, on which one performance analysis system is designed and realized. The architecture and the central techniques of system are discussed detail. Central techniques include the arithmetic of intelligent decision machine based on class mining and the principle of performance analysis machine which can effectively diagnose network. Practical application shows that the system can effectively diagnose and forecast the network.
