Abstract

A method and system for configuring one or more prospective-participant nodes as participant nodes so as to enable the prospective-participant nodes to engage in a peer-to-peer communication is provided. In one exemplary embodiment, the method and system may be embodied as a common application that includes logic, in hardware or software form, for carrying out one or more of the functions for configuring one or more prospective-participant nodes as a participant node in a peer-to-peer network.

In carrying out these functions, one of the participant nodes discovers its network-connection settings, and based on these settings, generates participant-node-configuration data that includes one or more network connection settings that define how to address the prospective-participant node as a participant node.

When desiring to join the peer-to-peer network, the prospective-participant node and the participant node may establish a point-to-point communication link by engaging in a discovery process using so as to establish a data-link layer connection. After completing negotiation of the data-link-layer connection, the prospective-participant node and the participant node may communicate over the data-link-layer connection.

The prospective-participant node may send to the participant node a request for network access. Responsively, the participant node sends to the prospective-participant node the participant-node-configuration data over the point-to-point connection. And the prospective-participant node configures itself using the participant-node-configuration data so as to become a participant node.

Claims

1. A method of setting up a prospective-participant node as a participant node in a peer-to-peer network to enable the prospective-participant node to engage in peer-to-peer communication in the peer-to-peer network with one or more other participant nodes, wherein each of the one or more other participant nodes is configured with a different respective Internet Protocol (IP) address defining how to address the participant node in the peer-to-peer network, the method comprising:

(a) at least one of the one or more other participant nodes using its IP address to generate participant-node-configuration data for configuring the prospective-participant node as a participant node in the peer-to-peer network, wherein the participant-node-configuration data includes an IP address (i) that is different from the IP address of the at least one of the one or more other participant nodes, and (ii) that defines how to address the prospective-participant node as a participant node in the peer-to-peer network; and

(b) the at least one of the one or more other participant nodes sending to the prospective-participant node the participant-node-configuration data, wherein the IP address included in the participant-node-configuration data is usable by the prospective-participant node as an address for the one or more other participant nodes to address the prospective-participant node as a participant node in the peer-to-peer network.

2. The method of claim 1, further comprising the at least one of the one or more other participant nodes using a network-configuration-discovery process to ascertain its IP address.

3. The method of claim 1, wherein element (b) is performed in response to the at least one of the one or more other participant nodes determining that network services are available to the prospective-participant node.

4. The method of claim 1, further comprising:

(c) establishing a point-to-point communication link between the at least one of the one or more other participant nodes and the prospective-participant node, wherein the at least one of the one or more other participant nodes sending to the prospective-participant node the participant-node-configuration data comprises the at least one of the one or more other participant nodes sending the participant-node-configuration data over the point-to-point communication link to the prospective-participant node.

5. The method of claim 4, wherein establishing a point-to-point communication link between the at least one of the one or more other participant nodes and the prospective-participant node comprises the at least one of the one or more other participant nodes engaging in a discovery process to establish a data-link-layer connection with the prospective-participant node.

6. The method of claim 4, further comprising the at least one of the one or more other participant nodes receiving a request for network access over the point-to-point communication link from the prospective-participant node.

7. The method of claim 6,

wherein the prospective-participant node is configured with a node identifier,

wherein the at least one of the one or more other participant nodes receiving the request for network access over the point-to-point communication link from the prospective-participant node comprises the at least one of the one or more other participant nodes receiving from the prospective-participant node a data-link-layer message containing the node identifier,

wherein the at least one of the one or more other participant nodes uses the node identifier to determine if any network services are available to the prospective-participant node, and

wherein element (b) is performed in response to the at least one of the one or more other participant nodes determining that network services are available to the prospective-participant node.

8. The method of claim 4, wherein elements (a), (b), and (c) of claim 4 are performed using at least one secure connection service.
