BitTorrent introduced an extremely efficient peer-to-peer networking technique for distributing a very large file (say, gigabytes) to a very large number of recipients (scalability should extend to millions) by splitting it into relatively small chunks (say, thousand chunks) in such a way that the recipients forward their downloaded chunks to further recipients. This project studies fully distributed analogues on BitTorrent from several points of view: algorithm design, testing and analysis.
- Design and study, using analytical models, different mediation algorithms applicable in a file distribution system based on chunk transfer along random encounters. The objective is to maximize the file distribution performance in terms like throughput, delay and reliability.
- Implement and test these algorithms in a working, experimental peer-to-peer content distribution system. Tests and performance measurements are made using partners' capabilities and, in particular, in the world-wide PlanetLab environment.
- Analyse and test the reliability and stability performance of various overlay network alternatives of the system.
