Testing of Probes for Network Traffic Monitoring

Abstract

In order to ensure a secure and stable Internet, administrators need tools for network monitoring which will allow them to analyze ongoing network traffic and respond to situations in a timely manner. One way to monitor traffic is to use monitoring probes. This thesis focuses on a thorough verification of the parameters of existing probes IPFIX probe and FlexProbe. FlexProbe is a network probe designed for the implementation of lawful interceptions developed at FIT BUT in cooperation with the Police of the Czech Republic. The IPFIX probe is developed by the CESNET association and is used for flow monitoring within the FlexProbe probe. In order to be able to operate the probes in the target environment for a long time, it is necessary to thoroughly test the device. The exact behavior of the probe is defined by the specification requirements that are developed for both probes. Based on the requirements, a comprehensive test system covering functional and performance parameters of the probes was designed. The tests are unified using a test framework and included in automated scenarios implemented in system Jenkins. At the end of the thesis, the coverage of the required properties of the probes and their performance is evaluated.
