Systems networks IP/MPLS monitoring model using NetFlow protocol

The monitoring of network operation, data collection, processing and reporting about the service quality for users in a suitable form for decision-making, is one of the main problems in a process of this problem´s solving. At the same time, the additional loading of service traffic, packets delay with a considerable number of errors can lead to network bandwidth decrease. The present paper proposes an analytical model which allows estimating the monitoring system probability-time parameters on the basis of NetFlow.
