Analysis and research of association pattern between network performances and faults in voip network

摘要

The paper focuses on implementation of association pattern between the network performances and the general network faults. We use network simulation tool, OPNET, to accomplish network simulations of different network faults and different situations based on VoIP. Network performance parameters such as end-to-end delay, jitter, traffic dropped, queuing delay, link throughout, link utilization are monitored and collected. The simulation results are processed using data mining software, Weka, to discover the association pattern.
