Problem addressed

Many times when one is downloading files from a ftp site, the bottleneck is at the server's end, because the server is handling many connections, even if the server has a greater bandwidth than the client. Popular programs are often mirrored at several sites, but this does not help the matter much; people tend to congregate at one site anyways.


Given that there are mirror-sites for the file one is downloading, one can in principle accomplish a much greater bandwidth by downloading from all the sites in parallel. This is accomplished by dividing the file being fetched into several pieces, and by getting each piece from a different server, and then re-assembling them.

If there are enough mirror sites, this partitioning makes it so that the bottleneck is now placed at the client end, maxing the client's connection.

Hence, we arrive at paraget, a parallel ftp-fetching program. paraget is designed to not only do basic n-equal-piece partitioning of a file and sending requests out to n servers for data, but to also be dynamic during the downloading process. For example if one server is too slow, and paraget was done with faster server downloading its piece
