Abstract

A data decoding system that includes a server-side proxy component and at least two back-end computers, where the server-side proxy component is configured, when it receives an encoding request from a client, to select a back-end computer to forward the encoding request to, based on either a pre-defined rule, load estimates for the at least two computers, estimated network throughputs across network paths to the two computers. In response to receiving this request, the back-end computer that is selected is configured to encode the request.

Claims

1. A system, comprising:

a network gateway configured as a server-side proxy connecting a client and a plurality of back-end computers;

wherein the server-side proxy component is configured, responsive to receiving an encoding request comprising raw data from a client, to select a back-end computer from the plurality of back-end computers to which the encoding request should be forwarded;

wherein the server-side proxy component is configured to select the back-end computer from the plurality of back-end computers based on factors comprising a pre-defined rule, load estimates for the plurality of back-end computers, and estimated network throughputs across network paths to each of the plurality of back-end computers; and

wherein the selected back-end computer is configured, responsive to receiving the encoding request, to encode the encoding request into an image of decodable indicia.

2. The system of claim 1, wherein the client is an encoded information reading (EIR) terminal comprising an RFID receiver configured to output the encoding request.

3. The system of claim 1, wherein the selected back-end computer is configured, responsive to successfully encoding the encoding request into the image of decodable indicia, to transmit the image of decodable indicia to the client.

4. The system of claim 1, wherein the selected back-end computer is configured, responsive to successfully encoding the encoding request into the image of decodable indicia, to store in a non-volatile memory the image of decodable indicia and/or the encoding request.

5. The system of claim 4, wherein the selected back-end computer is configured to, upon receipt of security credentials, grant access to the image of decodable indicia and/or the encoding request.

6. The system of claim 1, wherein the image of decodable indicia comprises a 1D bar code, a 2D bar code, and/or an OCR symbol.

7. The system of claim 1, wherein the selected back-end computer is configured, responsive to receiving the encoding request, to authenticate the client.

8. The system of claim 1, wherein the selected back-end computer is configured, responsive to receiving the encoding request, to establish a communication session with the client, wherein the communication session is supported using HTTP cookies and/or dynamic URLs.

9. A method, comprising the steps of:

transmitting a request comprising raw data from a client device to a network gateway configured as a server side proxy component that communicates with a computer;

receiving, with the computer, the request from the server-side proxy component, wherein the request was routed to the computer based on factors comprising a pre-defined rule, load estimates for the computer, and estimated network throughputs across network paths to the computer; and

encoding, with the computer, the request into an image of decodable indicia comprising a 1D bar code, a 2D bar code, and/or an OCR symbol.

10. The method of claim 9, wherein the client is an encoded information reading (EIR) terminal comprising an RFID receiver configured to output the request.

11. The method of claim 9, comprising transmitting, with the computer, the image of decodable indicia to the client, wherein the image of decodable indicia comprises a raw image byte stream, a compressed image byte stream, and/or a partial compressed image byte stream.

12. The method of claim 9, comprising storing, with the computer, the image of decodable indicia.

13. The method of claim 9, comprising:

in response to receiving the request, authenticating, with the computer, the client; and

in response to authenticating the client, initiating, with the computer, a communication session, wherein the communication session is supported using HTTP cookies and/or dynamic URLs.

14. A computer program product, comprising:

a computer-readable, tangible storage device; and

program instructions, stored on the storage device, which when executed by a computer, cause the computer to;

connect to a network gateway configured as a proxy component that connects the computer to a client and configures the computer to;

receive a request comprising raw data from a server-side proxy component that has received the request from a client, wherein the request was routed to the computer based on factors comprising a pre-defined rule, load estimates for the computer, and estimated network throughputs across network paths to the computer, wherein the pre-defined rule comprises a round-robin selection rule and/or a random selection rule; and

encode the request into an image of decodable indicia.

15. The computer program product of claim 14, wherein the program instructions comprise program instructions, which when executed by a computer, cause the computer to transmit the image of decodable indicia to the client.

16. The computer program product of claim 14, wherein the program instructions comprise program instructions, which when executed by a computer, cause the computer to store the image of decodable indicia.

17. The computer program product of claim 14, comprising program instructions, stored on the storage device, which when executed by a computer, cause the computer to, upon receipt of security credentials, grant access to the image of decodable indicia and/or the request.

18. The computer program product of claim 14, wherein the image of decodable indicia comprises a 1D bar code, a 2D bar code, and/or an OCR symbol.

19. The computer program product of claim 14, comprising program instructions, stored on the storage device, which when executed by a computer, cause the computer to, responsive to receiving the request, authenticate the client.

20. The computer program product of claim 14, comprising program instructions, stored on the storage device, which when executed by a computer, cause the computer, responsive to receiving the request, to establish a communication session with the client, wherein the communication session is supported using HTTP cookies and/or dynamic URLs.
