Abstract:
Methods and apparatus are provided for cooperative file distribution with receiver determined quality of services. A receiver obtains a file by selecting a target rate for downloading a file, identifying one or more unreliable data sources and one or more reliable data sources wherein each source contains one or more portions of the file, obtaining at least a portion of the file from the one or more unreliable data sources at a first rate, determining a throttle rate for downloading at least another portion of the file from the one or more reliable data sources, retrieving the at least another portion of the file from the one or more reliable data sources at a second rate, and adjusting the throttle rate such that an amount of data obtained from the one or more reliable data sources is minimized, and the target rate is maintained.
