Accessing Multiple Mirror Sites in Parallel Using Tornado Codes to Speed Up Downloads

This paper was published in the IEEE Infocom of 1999. The main objective, as the title suggested, is to speed up client download speed by accessing multiple mirror sites in parallel. The idea is to allow multiple senders in possession of the same file to simultaneously transmit data to the client using traditional end-to-end scheme, the data transmitted is the craftily encoded and sliced version of the file. Forward Error Correction code is used to achieve performance and avoid client feedback. The paper contains an overview on Tornado codes, the implementation, and the simulation results.
