- 2. Background Network Management Efficient , reliable and secure operations and management of networks, systems and services Functions F ault, C onfiguration, A ccounting, P erformance , and S ecurity Management CSED499 DPNM Lab.
- 3. Background CSED499 DPNM Lab. Network Performance Monitoring Network performance measurement and visualization (MRTG, Network Weather Map) Simple prediction of network performance POSNWS (POSTECH Network Weather Map Service) DPNM, POSTECH MRTG (Multi Router Traffic Grapher)
- 4. 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 CSED499 DPNM Lab.
- 5. 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 CSED499 DPNM Lab.
- 6. Contribution Dynamic Network Policy Planning (For manager) Control Limitation Optimization Network planning Prevention from overuse of network resources (For user) CSED499 DPNM Lab.
