Abstract

A system and method for implementing functionality within a network on behalf of first and second devices communicating with each other through the network. A front-end device is provided within the network that communicates data traffic with the first device. A back-end device is also implemented within the network and communicates data traffic with the second device. A communication channel couples the front-end device and the back-end device. Data traffic may be encoded into a different type or protocol for transport through the communication channel by the front-end device and back-end device. The front-end device and back-end device exchange quality of service information and may alter characteristics of the data traffic through the communication channel according to the quality of service information.

Claims

1. A method for transporting data from a first device to a second device through a limited bandwidth computer network comprising:

providing a front-end device comprising an interface to communicate data with at least one first device, said data comprising one of more data packets of a first type;

providing a back-end device comprising an interface to communicate data with at least one second device, said data comprising one or more data packets of said first type;

connecting a first wireless communication interface to said front-end device;

establishing at least one communication channel coupling the front-end device and the back-end device wherein at least a portion of the at least one communication channel is configured to transport data wirelessly via said first wireless communication interface between said at least one front-end device and said at least one back-end device in one or more data packets of a second type, said second type differing from said first type;

receiving said data comprising one or more data packets of said first type from said first device at said front-end device;

encoding said data received by said front-end device from said first device by converting said data into one or more data packets of said second type, wherein said step of encoding comprises changing characteristics of said data based at least in part on quality of service information;

transmitting said encoded data from said front-end device to said back-end device over said at least one communication channel with said first wireless communication interface;

decoding said encoded data received from said front-end device at said back-end device into data comprising packets of said first type; and

transmitting said decoded data from said back-end device to said second device.

2. The method of claim 1 further comprising connecting a second wireless communication interface to said back-end device and receiving said encoded data from said front-end device over said at least one communication channel with said second wireless communication interface.

3. The method of claim 1, wherein said one or more data packets of a first type are TCP/IP packets and said one or more data packets of a second type are not TCP/IP packets.

4. A system for transporting data from a first device to a second device through a limited bandwidth computer network comprising:

a front-end device configured to communicate data with at least one first device, said data comprising one of more data packets of a first type;

a back-end device configured to communicate data with at least one second device, said data comprising one or more data packets of said first type;

one or more wireless communication interfaces configured to facilitate wireless communication of said data between said front-end device and said back-end device in one or more data packets of a second type, said second type differing from said first type;

at least one communication channel configured to transport data between said at least one front-end device and said at least one back-end device in said one or more data packets of said second type using said one or more wireless communication interfaces, wherein said front-end device and said back-end device exchange network quality of service information between said front-end and said back-end over said at least one communication channel;

wherein said front-end device encodes said data received from said first computer by converting said data into one or more data packets of said second type; and

wherein said back-end device receives and decodes said encoded data from said front-end device into data comprising packets of said first type for use by said at least one second device.

5. The system of claim 4, wherein both said front-end device and said back-end device comprises one of the one or more wireless communication interfaces.

6. The system of claim 4, wherein only a portion of said at least one communication channel is wireless.

7. The system of claim 4, wherein said front-end device is configured to transmit said encoded data from said front-end device to said back-end device over said at least one communication channel.

8. The system of claim 4, wherein said back-end device is configured to decode said encoded data received from said front-end device into data comprising packets of said first type.

9. The system of claim 4, wherein said back-end device is configured to transmit said decoded data to said second device.

10. The system of claim 4, wherein said one or more data packets of a first type are TCP/IP packets and said one or more data packets of a second type are not TCP/IP packets.

11. A system for transporting data from a first device to a second device through a limited bandwidth computer network comprising:

a front-end device comprising an interface to communicate data with at least one first device, said data comprising one of more data packets of a first type, said front-end device configured to encode data of said first type into one or more data packets of a second type, said second type differing from said first type;

a back-end device comprising an interface to communicate data comprising one or more data packets of said first type with at least one second device, said back-end device configured to decode said encoded data into one or more data packets of said first type;

a wireless communication interface connected to said front-end device and configured to communicate one or more data packets of said second type; and

at least one communication channel coupling said front-end device and said back-end device wherein at least a portion of said at least one communication channel is configured to transport data between said front-end device and said back-end device in one or more data packets of said second type through said wireless communication interface.

12. The system of claim 11, wherein said wireless communication interface is part of said front-end device.

13. The system of claim 11, wherein said one or more data packets of a first type are TCP/IP packets and said one or more data packets of a second type are not TCP/IP packets.
