Abstract :
We present BTLab, a distributed platform to measure and analyze the differences between BitTorrent clients. Due to extensibility, and a certain vagueness in the BitTorrent specification, many clients diverge in some aspects from each other. Most research to date disregarded the effects of these differences. BTLab allows us to create and control BitTorrent swarms, composed of hundreds of clients of our choice. We use captured network traffic to measure the performance and uncover the reasons for observed differences. For our experiments, we deployed BTLab on a cluster and on Planetlab and selected four popular BitTorrent clients. Our analysis reveals flaws in piece selection and connection management algorithms that adversely affect the performance of some clients.
