摘要

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.

主权项

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.
