Abstract

Policy-based routing of packets over a peer-to-peer, quality of service connection includes sending a connection setup request, over a control connection to a connection establishing device, to dynamically establish the peer-to-peer, quality of service connection between a source peer implemented on at least one device and a destination peer implemented on at least one device. Packets originating from an application requiring a specified level of service are transmitted, from the source peer implemented on at least one device, over the peer-to-peer, quality of service connection. Packets originating from an application that does not require the specified level of service are transmitted, from the source peer implemented on at least one device, over a best effort connection.

Claims

1. A method of policy-based routing of packets over a peer-to-peer, quality of service connection, comprising:

sending a connection setup request, over a control connection to a connection establishing device, to dynamically establish the peer-to-peer, quality of service connection between a source peer implemented on at least one device and a destination peer implemented on at least one device;

transmitting from the source peer implemented on at least one device, over the peer-to-peer, quality of service connection, packets originating from an application requiring a specified level of service; and

transmitting from the source peer implemented on at least one device, over a best effort connection, packets originating from an application that does not require the specified level of service,

wherein the connection establishing device establishes the peer-to-peer, quality of service connection in response to the connection setup request.

2. The method according to claim 1,

wherein the peer-to-peer, quality of service connection bypasses an Internet service provider.

3. The method according to claim 1, further comprising:

dynamically selecting the destination peer implemented on at least one device.

4. The method according to claim 1,

wherein a portion of the control connection comprises a manually configured permanent virtual connection.

5. The method according to claim 1,

wherein a portion of the control connection comprises a second, best effort connection.

6. The method according to claim 1,

wherein the application requiring the specified level of service comprises a video conference application.

7. The method according to claim 1,

wherein the connection setup request includes an identification of the destination peer implemented on at least one device, a shared session key, a class of service and a traffic descriptor.

8. The method according to claim 1,

wherein the source peer implemented on at least one device sends the connection setup request.

9. The method according to claim 8,

wherein the destination peer implemented on at least one device sends a second connection setup request having common information with the connection setup request.

10. A source peer implemented on at least one device for policy-based routing of packets over a peer-to-peer, quality of service connection, comprising:

a first transmitter that sends a connection setup request, over a control connection to a connection establishing device, to dynamically establish the peer-to-peer, quality of service connection between the source peer implemented on at least one device and a destination peer implemented on at least one device; and

a second transmitter that transmits, over the peer-to-peer, quality of service connection, packets originating from an application requiring a specified level of service and that transmits, over a best effort connection, packets originating from an application that does not require the specified level of service,

wherein the connection establishing device establishes the peer-to-peer, quality of service connection in response to the connection setup request.

11. The source peer implemented on at least one device according to claim 10,

wherein the policy-based routing is based on a user session.

12. The source peer implemented on at least one device according to claim 11,

wherein policy-based routing terminates when the user session terminates.

13. The source peer implemented on at least one device according to claim 10,

wherein the packets originating from the application that does not require the specified level of service are sent to a default gateway, and

wherein the packets originating from the application requiring the specified level of service are sent to a separate gateway.

14. The source peer implemented on at least one device according to claim 10,

wherein the connection establishing device performs call admission control based on up-link port speeds and synchronization rates.

15. The source peer implemented on at least one device according to claim 10,

wherein the connection establishing device maintains state information for currently available bandwidth at the destination peer implemented on at least one device and the source peer implemented on at least one device.

16. The source peer implemented on at least one device according to claim 10,

wherein header patterns for the packets originating from the application requiring the specified level of service are matched with a stored pattern prior to transmitting over the peer-to-peer, quality of service connection.

17. A tangible storage medium storing a program, recorded on the tangible storage medium, for policy-based routing of packets over a peer-to-peer, quality of service connection, comprising:

a receiving code segment, recorded on the tangible storage medium, that receives a connection setup request from a source peer implemented on at least one device, over a control connection; and

an establishing code segment, recorded on the tangible storage medium, that dynamically establishes the peer-to-peer, quality of service connection between the source peer implemented on at least one device and a destination peer implemented on at least one device,

wherein packets originating from an application requiring a specified level of service are transmitted, over the peer-to-peer, quality of service connection, from the source peer implemented on at least one device, and

wherein packets originating from an application that does not require the specified level of service are transmitted, over a best effort connection, from the source peer implemented on at least one device.

18. The tangible storage medium according to claim 17, further comprising:

a selecting code segment, recorded on the tangible computer readable medium, that selects one of the source peer implemented on at least one device and the destination peer implemented on at least one device to originate the peer-to-peer, quality of service connection when the source peer implemented on at least one device and the destination peer implemented on at least one device are in a common domain.

19. The tangible storage medium according to claim 17, further comprising:

a second establishing code segment, recorded on the tangible storage medium, that establishes a first connection segment between the source peer implemented on at least one device and a common network to network interface meeting point and that establishes a second connection segment between the destination peer implemented on at least one device and the common network to network interface meeting point.

20. The tangible storage medium according to claim 17, further comprising:

an authentication code segment, recorded on the tangible storage medium, that obtains at least one of authorization information and authentication information from a server.
