Abstract

This invention relates to methods for downloading a user requested file via a peer-to-peer network, comprising the steps of: generating a second queue for containing one or more trying-to-connect peers, a third queue for containing currently-connected peers, and a forth queue for containing previously-connected peers; requesting from said servers one or more available peers, wherein said available peers having one or more blocks of said user requested file; placing said available peers in said second queue; connecting to the peers in the second queue, wherein upon successfully connecting to a peer in the second queue, placing such peer in said third queue; and downloading one or more blocks from the peers in said third queue.

Claims

1. A method for downloading a user requested file via a peer-to-peer network, comprising the steps of:

generating a second queue for containing one or more trying-to-connect peers, a third queue for containing currently-connected peers, and a forth queue for containing previously-connected peers;

requesting from said servers one or more available peers, wherein said available peers having one or more blocks of said user requested file;

placing said available peers in said second queue;

connecting to the peers in the second queue, wherein upon successfully connecting to a peer in the second queue, placing such peer in said third queue; and

downloading one or more blocks from the peers in said third queue.

2. The method of claim 1 wherein a first queue for holding one or more available peers is generated.

3. The method of claim 2 wherein in the placing step, said available peers are placed in said first queue;

and inserting the following step after the placing step;

placing the peers in the first queue in the second queue.

4. The method of claim 1 wherein a fifth queue for holding one or more failed peers is generated.

5. The method of claim 1 in the requesting step, wherein said server is requested for available peers at a pre-defined request rate and where the request rate is adjusted as a function of the total number of peers in said second queue and in said third queue.

6. The method of claim 5 in the requesting step, wherein a health value is generated for each of said available peers, and where the health value is used for adjusting the request rate.

7. The method of claim 1 in the downloading step, wherein a quality value is generated for one or more peers in the third queue, where said peers are shut down based upon said peers'"'"' respective quality value.

8. The method of claim 1 further comprising a step, after the connecting step, of:

uploading one or more blocks of a requested user file to one or more peers in said third queue.

9. The method of claim 1, whereupon downloading from a peer in said third queue is completed, placing such peer in said fourth queue.

10. The method of claim 1, whereupon downloading from a peer in said third queue is disconnected, placing such peer in said fourth queue.

11. The method of claim 8 in the uploading step, wherein said blocks are uploaded to a first predefined number of peers that are randomly selected from said queues, and wherein a second predefined number of peers of said selected peers are selected from a group of peers in said queues that have previously provided said user with one or more blocks of a file.

12. A method for downloading a user requested file via a peer-to-peer network, comprising the steps of:

generating a first queue for holding one or more available peers, a second queue for containing one or more trying-to-connect peers, a third queue for containing currently-connected peers, a forth queue for containing previously-connected peers, and a fifth queue for holding one or more failed peers;

requesting from said servers one or more available peers, wherein said available peers having one or more blocks of said user requested file;

placing said available peers in said first queue;

placing the peers in the first queue in the second queue;

connecting to the peers in the second queue, wherein upon successfully connecting to a peer in the second queue, placing such peer in said third queue; and

downloading one or more blocks from the peers in said third queue.

13. The method of claim 12 in the requesting step, wherein said server is requested for available peers at a pre-defined request rate and where the request rate is adjusted as a function of the total number of peers in said second queue and in said third queue.

14. The method of claim 13 in the requesting step, wherein a health value is generated for each of said available peers, and where the health value is used for adjusting the request rate.

15. The method of claim 12 in the downloading step, wherein a quality value is generated for one or more peers in the third queue, where said peers are shut down based upon said peers'"'"' respective quality value.

16. The method of claim 12 further comprising a step, after the connecting step, of:

uploading one or more blocks of a requested user file to one or more peers in said third queue.

17. The method of claim 12, whereupon downloading from a peer in said third queue is completed, placing such peer in said fourth queue.

18. The method of claim 12, whereupon downloading from a peer in said third queue is disconnected, placing such peer in said fourth queue.

19. The method of claim 16 in the uploading step, wherein said blocks are uploaded to a maximum of eight peers that are randomly selected from said third queue, and wherein seven peers of said selected peers are selected from a group of peers in said third queue that have previously provided said user with one or more blocks of a file.

20. A method for downloading a user requested file via a peer-to-peer network, comprising the steps of:

generating a first queue for holding one or more available peers, a second queue for containing one or more trying-to-connect peers, a third queue for containing currently-connected peers, a forth queue for containing previously-connected peers, and a fifth queue for holding one or more failed peers;

requesting from said servers one or more available peers, wherein said available peers having one or more blocks of said user requested file, wherein said server is requested for available peers at a pre-defined request rate and where the request rate is adjusted as a function of the total number of peers in said second queue and in said third queue, and wherein a health value is generated for each of said available peers, and where the health value is used for adjusting the request rate;

placing said available peers in said first queue;

placing the peers in the first queue in the second queue;

connecting to the peers in the second queue, wherein upon successfully connecting to a peer in the second queue, placing such peer in said third queue;

uploading one or more blocks of a requested user file to one or more peers in said third queue, wherein said blocks are uploaded to a maximum of eight peers that are randomly selected from said third queue, and wherein seven peers of said selected peers are selected from a group of peers in said third queue that have previously provided said user with one or more blocks of a file; and

downloading one or more blocks from the peers in said third queue, wherein a quality value is generated for one or more peers in the third queue, where said peers are shut down based upon said peers'"'"' respective quality value, whereupon downloading from a peer in said third queue is completed, placing such peer in said fourth queue, and whereupon downloading from a peer in said third queue is disconnected, placing such peer in said fourth queue.
