Abstract

A server terminal is interconnected with a number of client/peer terminals, as part of a network. For chargeable peer-to-peer file downloads, a client terminal establishes and accesses an account on the server. An information file associated with a data file of interest is obtained by the client from the server. The information file contains the network address of a tracker module. The client terminal accesses the tracker module to obtain the network locations of one or more peer terminals having sections/pieces of the data file stored thereon. The client terminal selects and contacts peer terminals for obtaining the data file sections. The client terminal and/or selected peer terminals securely transmit accounting data, relating to the amount of data transferred, to the tracker module, which forwards it to the server for billing purposes.

Claims

1. A method for transferring data over a network, said method comprising the steps of:

obtaining at least one portion of a data file from a first client terminal over a network, based on a location of said at least one data file portion as received from one of a server terminal and a tracking application associated with the server terminal; and

transmitting accounting data to one of the tracking application and the server terminal, said accounting data relating to the transfer of the at least one data file portion by the first client terminal over the network.

2. The method of claim 1 wherein the accounting data is automatically securely generated and transmitted during or subsequent to said at least one data file portion being obtained.

3. The method of claim 2 further comprising:

obtaining a plurality of data file portions from a plurality of client terminals over the network, based on respective locations of said portions as received from one of the server terminal and the tracking application, said plurality of data file portions comprising the entirety of the data file, wherein the accounting data further relates to the transfer of said data file portions by the plurality of client terminals over the network.

4. The method of claim 3 wherein the accounting data includes at least one of a rate at which each data file portion was obtained over the network and an amount of data transmitted over the network for obtaining each of said data file portions.

5. The method of claim 3 further comprising:

obtaining an information file associated with the data file from said server terminal, said information file including a location of the tracking application for obtaining the locations of the data file portions from the tracking application.

6. The method of claim 5 further comprising, prior to obtaining said information file:

accessing a secure account on said server terminal; and

accessing a database on said server terminal from said account to select said information file, where said information file is one of a plurality of information files on said server terminal each relating to a different data file.

7. The method of claim 2 further comprising, subsequent to obtaining said at least one data file portion:

transmitting said at least one data file portion to a second client terminal over the network upon request from said second client terminal, said second client terminal being in communication with said server terminal; and

transmitting additional accounting data to one of said tracking application and said server terminal relating to the transmission of said at least one data file portion to said second client terminal.

8. The method of claim 7 wherein the additional accounting data includes at least one of (i) a rate at which each of the at least one data file portion was transmitted over the network to the second client terminal and (ii) an amount of data in each of said at least one data file.

9. The method of claim 2 further comprising:

receiving a plurality of network locations from said tracking application, said network locations being respectively associated with a plurality of client terminals each having said at least one data file portion; and

selecting one of said plurality of client terminals for obtaining said at least one data file portion.

10. A method for transferring data over a network, said method comprising the steps of:

transmitting to a first client terminal a location of at least one section of a data file stored on a second client terminal, upon request from the first client terminal; and

receiving accounting data originating from at least one of said first client terminal and said second client terminal, said accounting data relating to a transfer of said at least one data file section from the second terminal to the first terminal over the network.

11. The method of claim 10 wherein:

the location of the at least one data file section is transmitted from one of a server terminal and a tracker module, wherein at least one of said server terminal and said tracker module is in communication with at least one of said first client terminal and said second client terminal; and

the accounting data is received by at least one of said server terminal and said tracker module.

12. The method of claim 11 wherein:

the accounting data is received by said tracker module; and

the method further comprises transmitting said accounting data to the server terminal for billing purposes.

13. The method of claim 10 wherein the accounting data includes at least one of a rate at which each of the at least one data file section was transferred over the network and an amount of data in each of said at least one data file section.

14. The method of claim 13 further comprising:

establishing a secure connection with said at least one of the first client terminal and the second client terminal for securely receiving said accounting data there from.

15. The method of claim 10 further comprising:

establishing a secure connection with said at least one of the first client terminal and the second client terminal for securely receiving said accounting data there from.

16. The method of claim 10 further comprising:

transmitting to the first client terminal a location of each of a plurality of peer client terminals, said plurality of peer client terminals including the second client terminal, each of said peer client terminals having the at least on data file section stored thereon.

17. A file download system comprising:

a client module configured to run on a first client terminal for managing transfer of data files to said first client terminal;

wherein the client module is configured to obtain one or more network locations of each of said data files from one of a server terminal and a tracker module in communication with said server terminal;

and wherein the client module is configured to automatically securely transmit accounting data to one of said server terminal and said tracker module, said accounting data relating to the transfer of said data files from one or more second client terminals to the first client terminal, said one or more second client terminals being associated with the one or more network locations.

18. The system of claim 17 wherein the data files each comprise one section of a composite data file.

19. The system of claim 18 wherein the accounting data includes at least one of a rate at which each of said data files was transferred over the network and an amount of data in each of said data files, said accounting data being used by at least one of the tracker module and the server terminal for generating billing data.

20. The system of claim 19 wherein:

the client module is configured to access the tracker module for obtaining said one or more network locations of the data files, said tracker module being accessed by the client module at a network address of the tracker module contained in an information file, wherein the information file relates to the composite data file and is obtained from the server terminal; and

the information file is one of a plurality of information files stored on or otherwise accessible by the server terminal, each of said information files relating to a different composite data file sections of which are available for peer-to-peer transfer over said network.
