Abstract:

As peertopeer streaming service on the Internet becomes more and more popular, simulators are necessary for the research and improvement of the peertopeer streaming systems. However, the existing simulators are all hard to extend their functions, which is inconvenient for research workers to achieve their goals. Therefore, we design and implement an Extensible PeertoPeer Streaming simulator: EPSS, which is an eventdriven, packetlevel and pythonbased simulator. In order to make EPSS extensible, we make a clear division of modules and extensible design of interfaces. The results of our experiments show that EPSS is not only easy to extend its functions but also scalable, so it is a better choice for the research workers of P2P streaming.
