ABSTRACT:
Apparatus and methods are disclosed for optimizing the transfer time of files in a peer-to-peer network. In disclosed embodiments, a requesting peer desires to transfer a file from a group of supplying peers creates a list of segments available of the file to be transferred available from each of the supplying peers, and orders the list in order of increasing segment size available. The supplying peers are then grouped based on available segments. Then, beginning with the group of supplying peers having the largest portion of the file to be transferred, the requesting peer assigning segments to transfer and a corresponding transfer time to each of the members of the group of supplying peers. The requesting peer then transfers in parallel the assigned segments from the group of supplying peers.
