As demand for bandwidth on the Internet continues to rocket, it becomes increasingly important to expand the existing infrastructure and to fairly allocate scarce network resources to improve user welfare. This paper introduces a paradigm for accessing information on the Internet whereby previously unused resources, those of the users themselves, play a central role in allowing users to bypass network congestion under “flash-crowd” conditions, where a large number of users from many networks retrieve the same set of files from a server over a short period of time. Simulations demonstrate the feasibility of this approach: a user obtains speedy access to files on servers under flash-crowd conditions in exchange for holding the file for a short period of time, within which, she serves at most two other users. |
