Methods and apparatus for identifying peers on a peer-to-peer network
View Patent ↗Methods and apparatus are provided for identifying participants in a peer-to-peer network, such as an Ares™ network. Peers are identified by sending a bootstrap request message to at least one peer; receiving a response from the at least one peer to the bootstrap request, wherein the response identifies one or more additional peers; and repeating the sending and receiving steps for the one or more additional peers until the bootstrap response satisfies one or more predefined criteria. The predefined criteria can be that the bootstrap response does not identify at least one new peer within a predefined period of time, or that the bootstrap response does not identify at least one new peer at all. The bootstrap requests are generally sent only to peers that have not been previously contacted. The bootstrap request message may comprise, for example, only one packet and requests that the recipient identify a predefined number of random peers. A list of identified peers can be presented to a user, for example, based on one or more demographic criteria.
1. A method for identifying participants in a peer-to-peer network, comprising:
sending a bootstrap request message using at least one network to at least one peer to discover one or more additional peers that were previously not identified;
receiving, using the at least one network, a response from the at least one peer to the bootstrap request, wherein the response identifies one or more additional peers that were previously not identified;
adding, using at least one hardware device, said one or more previously unidentified additional peers to at least one record stored in at least one memory comprising a listing of a group of peers to be contacted; and
repeating the sending and receiving steps for the one or more additional peers in said group of peers in the at least one record stored in the at least one memory until the group of peers to be contacted in the at least one record stored in the at least one memory comprises an empty set for a predefined period of time.
2. The method of claim 1 , wherein the sending step ensures that the at least one peer has not been previously contacted.
3. The method of claim 1 , wherein the bootstrap request message comprises only one packet.
4. The method of claim 1 , wherein the bootstrap request message requests that the recipient identify a predefined number of random peers.
5. The method of claim 1 , further comprising the step of recording one or more of an IP address, a port and an identifier for each of the identified one or more additional peers.
6. The method of claim 1 , further comprising the step of recording each of the identified one or more additional peers that were not previously known in a list.
7. The method of claim 6 , further comprising the step of presenting the list of peers to a user.
8. The method of claim 6 , further comprising the step of presenting the list of peers to a user based on one or more demographic criteria.
9. The method of claim 1 , wherein at least one of the identified one or more additional peers are behind one or more of a network address translator (NAT) and a firewall.
10. A system for identifying participants in a peer-to-peer network, comprising:
a memory; and
at least one processor, coupled to the memory, operative to:
send a bootstrap request message to at least one peer to discover one or more additional peers that were previously not identified;
receive a response from the at least one peer to the bootstrap request, wherein the response identifies one or more additional peers;
add said one or more previously unidentified additional peers to a group of peers to be contacted; and
repeat the sending and receiving for the one or more additional peers in said group until the group of peers to be contacted comprises an empty set for a predefined period of time.
11. The system of claim 10 , wherein the peer-to-peer network is an Ares network.
12. The system of claim 10 , wherein the bootstrap request message is only sent to at least one peer that has not been previously contacted.
13. The system of claim 10 , wherein the bootstrap request message comprises only one packet.
14. The system of claim 10 , wherein the bootstrap request message requests that the recipient identify a predefined number of random peers.
15. The system of claim 10 , wherein one or more of an IP address, a port and an identifier are recorded for each of the identified one or more additional peers.
16. The system of claim 10 , wherein the processor is further configured to to present a list of the identified peers to a user.
17. An article of manufacture for identifying participants in a peer-to-peer network, comprising a tangible, non-transitory computer readable recordable storage medium containing one or more programs which when executed implement the steps of:
sending a bootstrap request message using at least one network to at least one peer to discover one or more additional peers that were previously not identified;
receiving, using the at least one network, a response from the at least one peer to the bootstrap request, wherein the response identifies one or more additional peers that were previously not identified;
adding, using at least one hardware device, said one or more previously unidentified additional peers to at least one record stored in at least one memory comprising a listing of a group of peers to be contacted; and
repeating the sending and receiving steps for the one or more additional peers in said group of peers in the at least one record stored in the at least one memory until the group of peers to be contacted in the at least one record stored in the at least one memory comprises an empty set for a predefined period of time.
18. The article of manufacture of claim 17 , wherein the sending step ensures that the at least one peer has not been previously contacted.
19. The article of manufacture of claim 17 , wherein the bootstrap request message comprises only one packet.
20. The article of manufacture of claim 17 , wherein the bootstrap request message requests that the recipient identify a predefined number of random peers.
