Kvalitetsmätning av videoströmmar hos en internetleverantör : En jämförelse mellan en kommersiell och en open source-lösning

Sammanfattning

In this work, an open source-based solution for measuring the quality of video streams from an ISP has been developed. The goals with the work has been to see how much cheaper the open source solution is in comparison with the company’s already implemented commercial solution, if the data collected by the new solution is as reliable as the existing solution, and to see if the microcontroller that is used is powerful enough to replace the current one. The microcontroller used was a Raspberry Pi 4 model b. To see how much load the microcontroller could handle a stress test was conducted where the number of parallel video streams was increased until the resources on the device were maxed out. Measurement points in the unit that were checked during the stress test were CPU. The measurements showed that it was able to monitor 15 parallel currents before resources ran out. The open source-based solution cost SEK 1548 per unit while the cost for the commercial solution was SEK 10898kr per unit. The data collected by the open source solution proved to be as reliable as the commercial solution
