Abstract

Systems and methods are disclosed for reducing bandwidth during the transmission of data between first and second devices over a network. One method includes: receiving a first data request from the first device; generating a first request identifier associated with the first data request; transmitting to the first device a response to the first data request and the first request identifier associated with the first data request; receiving, from the first device, a partial second data request, the partial second data request including the first request identifier associated with the first data request, and a differential between the first data request and the second data request; and constructing, at the second device, a full second data request, based on a comparison between the first data request, fetched using the first request identifier, and the received differential between the first data request and the second data request.

First claim

What is claimed is:

1. A method for reducing bandwidth during the transmission of data between first and second devices over a network, the method including:
receiving, from the first device over the network, a first data request;
receiving, from the first device over the network, a partial second data request, the partial second data request including a differential between the first data request and the second data request; and
constructing, at the second device, a full second data request, based on a comparison between the first data request and the received differential between the first data request and the second data request by swapping a payload element in the first data request with a payload element in the received differential between the first data request and the second data request.

2. The method of claim 1 , further comprising:
generating, at the second device, a response to the full second data request; and
transmitting, to the first device over the network, a differential between the response to the first data request and the response to the full second data request.

3. The method of claim 2 , wherein the first device constructs a full second response, based on a comparison between the first data response and the received differential between the first data response and the full second data response.

4. The method of claim 1 , further comprising:
generating, at the second device, a response to the full second data request; and
transmitting, to the first device over the network, a differential between the response to the first data request and the response to the full second data request.

5. The method of claim 4 , wherein the first device constructs a full second response, based on a comparison between the first data response and the received differential between the first data response and the full second data response.

6. The method of claim 1 , wherein the response to the first data request is stored at the first device.

7. The method of claim 1 , wherein, constructing, at the second device, the full second data request, is performed by merging the received differential between the first data request and the second data request into the first data request.

8. The method of claim 1 , wherein the first device is a personal computer, tablet computer, or smartphone and the second device is a server executing a Web-based Simple Object Access Protocol (“SOAP”) service, Extensible Markup Language (“XML”) service, or Representational State Transfer (“REST”) service.

9. A system for reducing bandwidth during the transmission of data between first and second devices over a network, the system including:
a data storage device storing instructions for reducing bandwidth during the transmission of data between first and second devices over a network;
a processor configured to execute the instructions to perform a method including:
receiving, from the first device over the network, a first data request;
receiving, from the first device over the network, a partial second data request, the partial second data request including a differential between the first data request and the second data request; and
constructing, at the second device, a full second data request, based on a comparison between the first data request and the received differential between the first data request and the second data request by swapping a payload element in the first data request with a payload element in the received differential between the first data request and the second data request.

10. The system of claim 9 , wherein the processor is further configured for:
generating, at the second device, a response to the full second data request; and
transmitting, to the first device over the network, a differential between the response to the first data request and the response to the full second data request.

11. The system of claim 10 , wherein the first device constructs a full second response, based on a comparison between the first data response and the received differential between the first data response and the full second data response.

12. The system of claim 9 , wherein the processor is further configured for:
generating, at the second device, a response to the full second data request; and
transmitting, to the first device over the network, a differential between the response to the first data request and the response to the full second data request.

13. The system of claim 12 , wherein the first device constructs a full second response, based on a comparison between the first data response and the received differential between the first data response and the full second data response.

14. The system of claim 9 , wherein the response to the first data request is stored at the first device.

15. The system of claim 9 , wherein, constructing, at the second device, the full second data request, is performed by merging the received differential between the first data request and the second data request into the first data request.

16. A non-transitory computer readable medium storing instructions that, when executed by a computer, cause the computer to perform a method of reducing bandwidth during the transmission of data between first and second devices over a network, the method including:
receiving, from the first device over the network, a first data request;
receiving, from the first device over the network, a partial second data request, the partial second data request including a differential between the first data request and the second data request; and
constructing, at the second device, a full second data request, based on a comparison between the first data request and the received differential between the first data request and the second data request by swapping a payload element in the first data request with a payload element in the received differential between the first data request and the second data request.
