Abstract

In an example embodiment, a virtual conference is established with a server and a plurality of endpoint devices. One endpoint device, acting as a sender, may transfer a file to N other endpoint devices, acting as receivers. The sender divides the file in at least N segments and delivers one segment to each receiver. Receivers then request the next desired segment from one or more devices containing that segment. If devices hold the segment, the segment may be divided into parts, and one part may be requested from each device.
