Abstract [en]

This paper focuses on estimating network performance in order to make proper decisions regarding data flow path selection. The purpose is to estimate the available bandwidth without flooding the network with traffic like traditional bandwidth measurement tools such as Iperf. By using small datagrams to probe the network rather than flooding the link, delay and jitter can be measured and used for calculations. The idea is to use statistical information about the delay to make an acceptable estimation of the available bandwidth. Lntransform of delay and standard deviation of delay were found to be the most accurate parameters and provide the best correlation. Also, some network technologies have a significant difference in up and downlink delay. This can pose a problem when estimating the link performance. Therefore this paper also proposes a solution to handle measurements in asymmetrical links.
