Abstract

Embodiments of systems and methods for data transfer are presented herein. Specifically, embodiments of such a data transfer methodology may utilize one or more transmission channels for the transmission of the data to be transferred. In addition, a control channel in a different protocol than the transmission channels may be utilized to transmit control information between the sender and recipient. The rate at which data is sent on the transmission channels may be adjusted or the transmission of data on the transmission channel prioritized.

Claims

1. A system, comprising:

a computing device coupled to a network, including;

a processor; and

a computer readable medium comprising instructions executable to implement a first protocol module, wherein the protocol module is configured to;

receive data for transmission,

establish a control channel with a second protocol module at a second computer device over the network, wherein the control channel utilizes a first protocol,

establish a transmission channel with the second protocol module at the second computer device over the network, wherein the transmission channel utilizes a second protocol,

transmit the data over the transmission channel,

receive control data over the control channel, and

adjust the transmission of data on the transmission channel based on the control data received on the control channel.

2. The system of claim 1, wherein the first protocol is a reliable protocol and the second protocol is an unreliable protocol.

3. The system of claim 2, wherein the first protocol is TCP and the second protocol is UDP.

4. The system of claim 1, wherein adjusting the transmission of data comprises adjusting a send rate or prioritizing a set of packets of the data for transmission on the transmission channel.

5. The system of claim 4, wherein prioritizing the set of packets of the data for transmission over the transmission channel is done based on a retransmit time.

6. The system of claim 5, wherein the protocol module is further configured to adjust the retransmit time based on a network round trip time determined using the control data received on the control channel.

7. The system of claim 1, wherein the control data includes a STAT message and an ACK message and the STAT message includes a discard count, a duplicate count, a receive rate, a receive count or a network loss rate.

8. A method for data transmission, comprising:

receiving data for transmission at a first protocol module on a first computing device;

establishing a control channel with a second protocol module at a second computer device over a network, wherein the control channel utilizes a first protocol;

establishing a transmission channel with the second protocol module at the second computer device over the network, wherein the transmission channel utilizes a second protocol;

transmitting the data over the transmission channel;

receiving control data over the control channel; and

adjusting the transmission of data on the transmission channel based on the control data received on the control channel.

9. The method of claim 8, wherein the first protocol is a reliable protocol and the second protocol is an unreliable protocol.

10. The method of claim 9, wherein the first protocol is TCP and the second protocol is UDP.

11. The method of claim 8, wherein adjusting the transmission of data comprises adjusting a send rate or prioritizing a set of packets of the data for transmission on the transmission channel.

12. The method of claim 11, wherein prioritizing the set of packets of the data for transmission over the transmission channel is done based on a retransmit time.

13. The method of claim 12, further comprising adjusting the retransmit time based on a network round trip time determined using the control data received on the control channel.

14. The method of claim 8, wherein the control data includes a STAT message and an ACK message and the STAT message includes a discard count, a duplicate count, a receive rate, a receive count or a network loss rate.

15. A non-transitory computer readable medium, comprising instructions for:

receiving data for transmission at a first protocol module on a first computing device;

establishing a control channel with a second protocol module at a second computer device over a network, wherein the control channel utilizes a first protocol;

establishing a transmission channel with the second protocol module at the second computer device over the network, wherein the transmission channel utilizes a second protocol;

transmitting the data over the transmission channel;

receiving control data over the control channel; and

adjusting the transmission of data on the transmission channel based on the control data received on the control channel.

16. The computer readable medium of claim 15, wherein the first protocol is a reliable protocol and the second protocol is an unreliable protocol.

17. The computer readable medium of claim 16, wherein the first protocol is TCP and the second protocol is UDP.

18. The computer readable medium of claim 15, wherein adjusting the transmission of data comprises adjusting a send rate or prioritizing a set of packets of the data for transmission on the transmission channel.

19. The computer readable medium of claim 18, wherein prioritizing the set of packets of the data for transmission over the transmission channel is done based on a retransmit time.

20. The computer readable medium of claim 19, further comprising instructions for adjusting the retransmit time based on a network round trip time determined using the control data received on the control channel.

21. The computer readable medium of claim 15, wherein the control data includes a STAT message and an ACK message and the STAT message includes a discard count, a duplicate count, a receive rate, a receive count or a network loss rate.

22. A system, comprising:

a computing device coupled to a network, including;

a processor; and

a computer readable medium comprising instructions executable to implement a first protocol module, wherein the first protocol module is configured to;

receive data for transmission,

establish a control channel with a second protocol module at a second computer device over the network, wherein the control channel utilizes Transmission Control Protocol (TCP),

establish a transmission channel with the second protocol module at the second computer device over the network, wherein the transmission channel utilizes User Datagram Protocol (UDP),

transmit the data over the transmission channel at a first data rate,

receive control data over the control channel, and

adjust the transmission of data on the transmission channel based on the control data received on the control channel, wherein adjusting the transmission of data comprises transmitting the data over the transmission channel at a second data rate or prioritizing the transmission of the data over the transmission channel.

23. The system of claim 22, wherein the second data rate is less than the first data rate.

24. The system of claim 22, wherein the second data rate is greater than the first data rate.

25. The system of claim 22, wherein the control data is used to determine a round trip time of the control data on the network between the first protocol module and the second protocol module and the transmission of data on the transmission channel is adjusted based on the round trip time.

26. The system of claim 25, wherein the data is transmitted as a set of packets.

27. The system of claim 26, wherein the first protocol module is configured to determine that at least one packet of the set of packets is lost based on the round trip time.

28. The system of claim 27, wherein the prioritization of the transmission of data is done based on the determination that the at least one packet is lost.

29. The system of claim 28, wherein the prioritization of the transmission of data on the transmission channel comprises the prioritization of the transmission of the at least one packet.
