METHOD, SYSTEM AND APPARATUS FOR REMOTE SOFTWARE UPGRADE OF AN EMBEDDED DEVICE

摘要

A system, method and apparatus for remote upgrade of the software of an embedded device supporting packet-based communication. A packet-based communication path is provided between a remote device and the embedded device. An intermediate device is placed in the packet-based communication path as a local node directly coupled to the embedded device. The intermediate device includes packet-forwarding means for carrying out normal communication between the remote device and the embedded device. The software of the embedded device is upgraded by i) transferring software upgrade data from the remote device to the intermediat e device, ii) transferring the software upgrade data from the intermediate device to the embedded device, and iii) carrying out an upgrade process on the embedded device that loads the software upgrade data on the embedded device.
