NETWORK PERFORMANCE MONITORING USING THRESHOLD CROSSING ALERTS

Threshold crossing alerts (TCAs) indicate to a management system that a management variable, associated with the state, performance or health of the network, has crossed a certain threshold. The timely detection of TCAs is essential to proactive management. This paper focuses on detecting TCAs for network-level variables, which are computed from device-level variables using aggregation functions, such as SUM, MAX, or AVERAGE. This paper proposes a methodology which could be managing the individual network elements deployed in the telecommunication network environment. This proposed system uses local thresholds and is adaptable to changes in network state and topology.
