Abstract

A system that transmits encapsulated media receives a first request to establish a tunnel with a stream based transport layer, the first request including a tag. The system receives a second request to establish the tunnel with a datagram based transport layer, the second request including the tag. The system establishes the tunnel with the stream based transport layer and receives the encapsulated media over the stream based transport layer. The system establishes the datagram based transport layer for the tunnel in addition to the stream based transport layer and receives the encapsulated media over the datagram based transport layer. The system then releases the stream based transport layer.

First claim

What is claimed is:

1. A method of transmitting encapsulated media, the method comprising:
receiving a first request to establish a tunnel with a stream based transport layer, the first request comprising a tag;
receiving a second request to establish the tunnel with a datagram based transport layer, the second request comprising the tag;
establishing the tunnel with the stream based transport layer and receiving the encapsulated media over the stream based transport layer;
establishing the datagram based transport layer for the tunnel in addition to the stream based transport layer and receiving the encapsulated media over the datagram based transport layer; and
releasing the stream based transport layer.

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

3. The method of claim 1 , wherein the stream based transport layer transmits the encapsulated media using a transmission control protocol (TCP).

4. The method of claim 1 , wherein the datagram based transport layer transmits the encapsulated media using a User Datagram Protocol (UDP).

5. The method of claim 1 , wherein establishing the tunnel comprises assigning a tunnel identifier and Internet Protocol address to the tunnel.

6. The method of claim 1 , wherein the encapsulated media is transmitted over the stream based transport layer before the datagram based transport layer is established.

7. The method of claim 6 , wherein the encapsulated media is transmitted over the datagram based transport layer after the stream based transport layer is released.

8. The method of claim 1 , wherein the first request and the second request are received consecutively without any intervening requests.

9. A non-transitory computer readable medium having instructions stored thereon that, when executed by a processor, cause the processor to transmit encapsulated media, the transmitting comprising:
receiving a first request to establish a tunnel with a stream based transport layer, the first request comprising a tag;
receiving a second request to establish the tunnel with a datagram based transport layer, the second request comprising the tag;
establishing the tunnel with the stream based transport layer and receiving the encapsulated media over the stream based transport layer;
establishing the datagram based transport layer for the tunnel in addition to the stream based transport layer and receiving the encapsulated media over the datagram based transport layer; and
releasing the stream based transport layer.

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

11. The computer readable medium of claim 9 , wherein the stream based transport layer transmits the encapsulated media using a transmission control protocol (TCP).

12. The computer readable medium of claim 9 , wherein the datagram based transport layer transmits the encapsulated media using a User Datagram Protocol (UDP).

13. The computer readable medium of claim 9 , wherein establishing the tunnel comprises assigning a tunnel identifier and Internet Protocol address to the tunnel.

14. The computer readable medium of claim 9 , wherein the encapsulated media is transmitted over the stream based transport layer before the datagram based transport layer is established.

15. The computer readable medium of claim 14 , wherein the encapsulated media is transmitted over the datagram based transport layer after the stream based transport layer is released.

16. The computer readable medium of claim 9 , wherein the first request and the second request are received consecutively without any intervening requests.

17. A tunneling server in communication with a tunneling client for transmitting encapsulated media between the tunneling server and the tunneling client, the tunneling server comprising:
a processor; and
a storage device coupled to the processor that stores instructions that when executed by the processor, implement functionality comprising:
receiving a first request to establish a tunnel with a stream based transport layer, the first request comprising a tag;
receiving a second request to establish the tunnel with a datagram based transport layer, the second request comprising the tag;
establishing the tunnel with the stream based transport layer and receiving the encapsulated media over the stream based transport layer;
establishing the datagram based transport layer for the tunnel in addition to the stream based transport layer and receiving the encapsulated media over the datagram based transport layer; and
releasing the stream based transport layer.

18. The tunneling server of claim 17 , wherein the tunnel is established according to a tunneled services control function (TSCF) standard.

19. The tunneling server of claim 17 , wherein the stream based transport layer transmits the encapsulated media using a transmission control protocol (TCP).

20. The tunneling server of claim 17 , wherein the datagram based transport layer transmits the encapsulated media using a User Datagram Protocol (UDP).
