Facilitating file access from firewall-proteced nodes in a peer-to-peer network
First Claim
1. A method for facilitating file access in a peer-to-peer network, the peer-to-peer network including a plurality of nodes, wherein a portion of the nodes are separated from the network by a firewall device, the method comprising the steps of:
- (a) designating a first node that is not firewall protected to act as a proxy server;
(b) in response to determining that a second node is protected by a firewall, instructing the second node to establish a connection with the proxy server;
(c) sending an open connection request from the second node to the proxy server;
(d) in response to receiving a request from a third node for a file on the second node, instructing the third node to send the request to the proxy server; and
(e) forwarding the request from the proxy server to the second node as a response to the open connection request, thereby allowing other nodes to access files on the second node despite the presence of the firewall.

Abstract
A method and system for facilitating file access in a peer-to-peer network. The peer-to-peer network includes a plurality of nodes, where a portion of the nodes are separated from the network by a firewall device. The method and system include designating a first node on the network that is not firewall protected to act as a proxy server. In response to determining that a second node is protected by a firewall, the second node is instructed to establish a connection with the proxy server. An open connection request is then sent from the second node to the proxy server. In response to receiving a request from a third node to access a file on the second node, the method and system further include instructing the third node to send the request to the proxy server. The proxy server is then used to forward the request to the second node as a response to the open connection request, thereby allowing other nodes to access files on the second node despite the presence of the firewall.

10. A peer-to-peer file delivery network including a plurality of nodes, wherein a portion of the nodes are separated from the network by a firewall device, the network comprising the steps of:
-
means for designating a first node that is not firewall protected to act as a proxy server;
means for instructing a second node to establish a connection with the proxy server in response to determining that the second node is protected by a firewall;
means for sending an open connection request from the second node to the proxy server;
means for instructing a third node to send a request to the proxy server in response to receiving the request from the third node for a file on the second node; and
means for forwarding the request from the proxy server to the second node as a response to the open connection request, thereby allowing other nodes to access files on the second node despite the presence of the firewall. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 20, 21)

19. A method for facilitating file access in a peer-to-peer network, the peer-to-peer network including a plurality of nodes, wherein at least one of the nodes is protected from the network by a firewall device, the method comprising the steps of:
-
(a) instructing the firewall-protected client node to transmit a first request a first node on the network in order to establish an open connection with the first node;
(b) instructing other nodes in the network to send requests for files on the firewall-protected client to the first node;
(c) receiving a request on the first node for a file on the firewall-protected client from a second node;
(d) passing the request for the file over the open connection to the firewall-protected client as a response to the first request;
(e) responding to the request for the file by sending a response, which includes the file from the firewall-protected client to the first node; and
(f) passing the response from the first node to the second node, wherein the first node acts as a proxy between the firewall-protected node and the second node to allow the second node to access the file on the firewall-protected node.
