A trade-off analysis model: towards improving polling efficiency for network monitoring

One of the criticisms of network monitoring is the performance problems caused by the management traffic generated by he polling technique used to gather management information. This article presents a trade-off analysis model which enables the network management system to differentiate the polling frequencies systematically so as to collect data from the point of view of the whole network. The simulation results show that for various measurement objectives, the selective trade-off analysis approach is more efficient than at least that of a random polling scheme. and performs well across a wide range of traffic loads.
