1 A Dynamic Polling Scheme for the Network Monitoring Problem Feng Gao, Jairo Gutierrez* Dept. of Computer Science *Dept. of Management Science and Information Systems University of Auckland, New Zealand *

2 Introduction

3 Related Work Minimizing the monitoring cost associated with network monitoring Dynamic polling scheme based on time variations Distributed Network monitoring with Bounded Link Utilization Adaptive Sampling for network management A model for efficient configuration of management

4 Design Issues

5 A dynamic polling scheme

6 Polling Frequency Hierarchy

7 Decision making and Optimization Multiple choice decision making by using the AHP Selection based on management objectives Optimization by Branch-and-Bound

8 Simulation setup

9 Simulation Results

10 Simulation results (Contd) Fault timeMean Diff of RP (ms) Mean Diff of DP(ms) 25s s s s s s s

11 Discussion Improving of the AHP in real-time decision making Flexibility and scalability of the dynamic polling scheme Implementation issues A trade-off between the reduction of management efforts and the cost of additional computation

12 Conclusion and Future Work An optimization of network monitoring Future work How would this scheme be implemented on real time networked systems
