Problem Definition and Goal

Problem Definition– No satisfactory solution available for network

performance forecast– Currently, low accuracy of forecasting network

traffic with static policies (thresholds)

Goal– Development of network traffic forecasting

system with high accuracy by dynamic policy planning

Method

Notification network trouble in advance with high accuracy– Collect network traffic data from network

elements by SNMP– Apply various algorithms for dynamic planning– Compare and evaluate each method– Find an optimal solution– Use the forecast value as a dynamic threshold

(notification before event) Validation

– Apply this method to NMS for POSTECH Network

Contribution

Dynamic Network Policy Planning (For manager)– Control– Limitation– Optimization– Network planning

Prevention from overuse of network resources (For user)
