Abstract

As networks grow in complexity and scale, the importance of network performance monitoring and measurement also increases significantly. High data rates often lead to large amount of measurement results. Therefore, in order to prevent an exhaustion of the network resources and to reduce the measurement cost, a reduction of the collected data is required. A performance measurement method for estimating the actual network performance, experienced by the user, has been proposed. This study focuses on monitoring the network performance and estimates its main Quality of Service (QoS) parameters (delay, throughput, and jitter) through the use of a non-intrusive passive measurement method based on sampling methodologies. This method will overcome the drawbacks of both active and passive monitoring methods. That is because it measures the actual performance experienced by the user and requires reduced calculations of QoS parameters from the sampled packets. The validation of this approach was analysed and verified through simulations. Three different sampling techniques (systematic, random, and stratified) were investigated. The study indicated that an accurate estimation of the QoS parameters could be obtained without the need to measure across the whole packets of traffic information. As a result, the scheme has shown an estimation of the detailed characteristics of performance for each user. For a bottleneck based network topology and traffic conditions used, the random sampling showed the best overall performance.
