Abstract

A system establishes a main tunnel between a tunneling client and a tunneling server using a first socket, the main tunnel including a corresponding tunnel identifier and Internet Protocol (“IP”) address. The system traverses the encapsulated media over the main tunnel during the telecommunication session and then determines that a cloned tunnel is needed for the telecommunication session. The system establishes a cloned tunnel between the tunneling client and the tunneling server using a second socket that has been marked as a cloned tunnel candidate, where the cloned tunnel includes the corresponding tunnel identifier and IP address of the main tunnel. The system then traverses the encapsulated media over the cloned tunnel instead of the main tunnel during the telecommunication session.

First claim

What is claimed is:

1. A method of transmitting encapsulated media during a telecommunication session, the method comprising:
establishing a main tunnel between a tunneling client and a tunneling server using a first socket, the main tunnel comprising a corresponding tunnel identifier and Internet Protocol (IP) address;
initially traversing the encapsulated media over the main tunnel during the telecommunication session;
determining that a cloned tunnel is needed for the telecommunication session based on a detection of a degradation of the telecommunication session over the main tunnel;
establishing a cloned tunnel between the tunneling client and the tunneling server using a second socket that has been marked as a cloned tunnel candidate, wherein the cloned tunnel comprises the corresponding tunnel identifier and IP address of the main tunnel; and
after establishing the cloned tunnel, traversing the encapsulated media over the cloned tunnel instead of the main tunnel during the telecommunication session.

2. The method of claim 1 , wherein the main tunnel and the cloned tunnel are established according to a tunneled services control function (TSCF) standard.

3. The method of claim 1 , wherein the main tunnel terminates at a first interface associated with a first server at a service provider network and the cloned tunnel terminates at a second interface associated with a second server at the service provider network that is different than the first server.

4. The method of claim 2 , wherein the cloned tunnel is established without a use of TSCF service messages.

5. The method of claim 1 , wherein the main tunnel and the cloned tunnel comprise one of either a Transmission Control Protocol (TCP) transport or a User Datagram Protocol (UDP) transport.

6. The method of claim 1 , wherein the main tunnel and the cloned tunnel comprise a same inner layer and a different outer layer.

7. The method of claim 1 , further comprising traversing signaling traffic over the cloned tunnel instead of the main tunnel.

8. The method of claim 1 , wherein the detection of the degradation is based on a measurement of at least one of packet loss, jitter or latency.

9. A non-transitory computer readable medium having instructions stored thereon that, when executed by a processor, cause the processor to transmit encapsulated media during a telecommunication session, the transmitting comprising:
establishing a main tunnel between a tunneling client and a tunneling server using a first socket, the main tunnel comprising a corresponding tunnel identifier and Internet Protocol (IP) address;
initially traversing the encapsulated media over the main tunnel during the telecommunication session;
determining that a cloned tunnel is needed for the telecommunication session based on a detection of a degradation of the telecommunication session over the main tunnel;
establishing a cloned tunnel between the tunneling client and the tunneling server using a second socket that has been marked as a cloned tunnel candidate, wherein the cloned tunnel comprises the corresponding tunnel identifier and IP address of the main tunnel; and
after establishing the cloned tunnel, traversing the encapsulated media over the cloned tunnel instead of the main tunnel during the telecommunication session.

10. The computer readable medium of claim 9 , wherein the main tunnel and the cloned tunnel are established according to a tunneled services control function (TSCF) standard.

11. The computer readable medium of claim 9 , wherein the main tunnel terminates at a first interface associated with a first server at a service provider network and the cloned tunnel terminates at a second interface associated with a second server at the service provider network that is different than the first server.

12. The computer readable medium of claim 10 , wherein the cloned tunnel is established without a use of TSCF service messages.

13. The computer readable medium of claim 9 , wherein the main tunnel and the cloned tunnel comprise one of either a Transmission Control Protocol (TCP) transport or a User Datagram Protocol (UDP) transport.

14. The computer readable medium of claim 9 , wherein the main tunnel and the cloned tunnel comprise a same inner layer and a different outer layer.

15. The computer readable medium of claim 9 , the transmitting further comprising traversing signaling traffic over the cloned tunnel instead of the main tunnel.

16. The computer readable medium of claim 9 , wherein the detection of the degradation is based on a measurement of at least one of packet loss, jitter or latency.

17. A user equipment device comprising:
a processor coupled to a storage device that stores instructions, the processor executing the instructions to implement an application and a tunneling client;
the tunneling client configured to establish a main tunnel between a tunneling client and a tunneling server using a first socket, the main tunnel comprising a corresponding tunnel identifier and Internet Protocol (IP) address;
the tunneling client configured to initially traverse encapsulated media over the main tunnel during a telecommunication session;
the application configured to determining that a cloned tunnel is needed for the telecommunication session based on a detection of a degradation of the telecommunication session over the main tunnel;
the tunneling client configured to establish a cloned tunnel between the tunneling client and the tunneling server using a second socket that has been marked as a cloned tunnel candidate, wherein the cloned tunnel comprises the corresponding tunnel identifier and IP address of the main tunnel; and
the tunneling client configured to, after establishing the cloned tunnel, traverse the encapsulated media over the cloned tunnel instead of the main tunnel during the telecommunication session.

18. The user equipment device of claim 17 , wherein the main tunnel and the cloned tunnel are established according to a tunneled services control function (TSCF) standard.

19. The user equipment device of claim 17 , wherein the main tunnel terminates at a first interface associated with a first server at a service provider network and the cloned tunnel terminates at a second interface associated with a second server at the service provider network that is different than the first server.

20. The user equipment device of claim 18 , wherein the cloned tunnel is established without a use of TSCF service messages.
