Association pattern recognization by simulation between performance and faults in MAN

At present, network services have covered complex applications and value-added services, and service providers also need to consider service quality for customers´ satisfaction. The equipment performance and faults directly affect the quality of service. Therefore, analyzing the relationship of service performance (the traffic distribution, transmission delay etc.), the network performance and faults based on some typical applications is of great significance. This paper builds typical MAN (metropolitan area network) topologies and fault scenarios which carrying VoIP application. Through simulation, performance data collection and mining, the association between network performance and faults will be found as the important foundation of association recognition between network faults and service quality.
