Abstract

Claims (35)

1. A method for communication in a peer-to-peer (P2P) network, comprising:

a first peer in the P2P network receiving at least one network operation policy from a server peep in the P2P network in response to sending a join request to the server peer;

the first peer perusing the at least one network operation policy to select a primary Internet Protocol (IP) address from a plurality of IP addresses that identify the first peep, wherein the selected primary IP address complies with the at least one network operation policy;

the first peer providing the primary IP address to a second peer as an address the second peer is to use in initiating communication with the first peer, wherein the first peer provides the primary IP address to the second peer in a signaling stage;

the first peer providing to the second peer at least one additional IP address from the plurality of IP addresses as an address available to the second peer for use in communicating with the first peer, wherein the first peer provides the at least one additional IP address to the second peer in a data transmission stage;

the first peer establishing session with the second peer;

the first peer receiving an update request to update the network operation policy from the server peer;

the first peer updating the primary IP address based on the updated network operation policy while the session with the second peer is active; and

the first peer performing a connectivity check with the second peer using the updated primary IP address.

2. The method of claim 1 , wherein, when the P2P network is a managed network.

3. The method of claim 1 , wherein the first peer provides an update of the at least one additional IP address to the second peer in a data transmission stage.

4. A device configured to:

operate in a peer-to-peer (P2P network);

receive at least one network operation policy from a server peer in the P2P network;

use the at least one network operation policy to select a primary Internet Protocol (IP) address from a plurality of IP addresses that identify the device, the selected primary IP address compliant with the at least one network operation policy;

register the primary IP address in the P2P network;

establish a session with a second peer in the P2P network, wherein the device provides the primary IP address to the second peer in a signaling stage;

provide to the second peer at least one additional IP address from the plurality of IP addresses as an address available to the second peer for use in communicating with the device, wherein the device provides the at least one additional IP address to the second peer in a data transmission stage;

receive an update request to update the network operation policy from the server peer;

update the primary IP address in the P2P network based on the updated network operation policy while the session with second peer is active; and

perform a connectivity check with the second peer using the updated primary IP address.

5. The device of claim 4 , wherein, when the P2P network is a managed network.

6. The device of claim 4 , wherein the device is further configured to provide an update of the at least one additional IP address to the second peer in a data transmission stage.

7. A node configured to:

operate in a managed peer-to-peer (P2P) network;

receive at least one network operation policy from a server peer in a the P2P network;

use the at least one policy to select a primary Internet Protocol (IP) address from a plurality of IP addresses identifying the node to be used by at least one peer in the P2P network in communicating with the node, the primary IP address compliant with the at least one policy;

provide the primary address to a second node as an address the second node is to use in initiating communication with the node, wherein the node provides the primary IP address to the second node in a signaling stage;

provide at least one additional IP address to the second node in a data transmission stage;

establish a session with the second node;

receive a request from the server peer to update the network operation policy;

update the primary IP address based on the update network operation policy

while the session with the second node is active; and

perform a connectivity check with the second node using the updated primary IP address.

8. The node of claim 7 , wherein the node is further configured to provide an update of the additional IP address to the second node in the data transmission stage.
