Sammanfattning
Evaluating and testing changes or configurations to peer-to-peer systems, or even understanding their behaviour, can be complicated. One approach, is to simulate a peer-to-peer system and visualise the results. In this master’s thesis, a study is performed to understand how an actual implementation of a hybrid peer-to-peer live video streaming system behaves, and performs under different scenarios. The behaviour and performance of a hybrid live video streaming system, consisting of an unstructured mesh-pull-based P2P network and a classic content delivery network solution, is studied by simulating the system with different scenarios such as flash crowds, flash disconnects etc. The simulation tool includes a network model, taking latency and bandwidth into consideration. As expected, the mesh-based system performed well under user churn. Although the system consisted of approximately 80% free-riders, the utilisation of the content distribution network was reduced by 60% on average. The data analysis was successful in improving the system’s overall performance. Furthermore, the visualisations and data analysis were used to understand the system’s behaviour.
