DYNAMIC UPDATE SYSTEM FOR A REMOTE PHYSICAL DEVICE
A method for updating an embedded device that includes a processor that receives an image file including at least one of kernel software, hardware configuration data, and application software. The embedded device parses the image file to determine portions of the image file that have been indicated by at least one flag as being modified from that currently being included on the embedded device. The embedded device installing at least portions of the image file on the embedded device and resetting portions of the embedded device based upon the at least one flag.
1 . A distribution system that includes a head end connected to a plurality of customer devices through a transmission network that includes a node that converts digital data to data suitable for said plurality of customer devices, where said node includes a processor, the node performing the following steps using the processor:
(a) said node receiving a single image file including (i) kernel software, (ii) hardware configuration data, and (iii) application software;
(b) said node parsing said image file to determine portions of said image file that have been indicated by at least one flag as being modified from that currently being included on said node, and determine portions of said image file that have been indicated by said at least one flag as not being modified from that currently being included on said node;
(c) said node installing at least portions of said image file on said node based upon said at least one flag as being modified and resetting portions of said node based upon said at least one flag as being modified.
2 . The distribution system of claim 1 further comprising said node resetting software applications in a control plane.
3 . The distribution system of claim 2 further comprising modifying at least one of said software applications as a result of resetting said node.
4 . The distribution system of claim 1 further comprising modifying said software dataplane as a result of resetting said node.
5 . The distribution system of claim 1 further comprising said node resetting software applications in a software dataplane.
6 . The distribution system of claim 1 further comprising a hard reset of said node.
7 . The distribution system of claim 1 further comprising a soft reset of said node.
8 - 10 . (canceled)
11 . A method for updating an embedded device that includes a processor, comprising the steps of:
(a) said embedded device receiving a single image file including (i) kernel software, (ii) hardware configuration data, and (iii) application software;
(b) said embedded device parsing said image file to determine portions of said image file that have been indicated by at least one flag as being modified from that currently being included on said embedded device, and determine portions of said image file that have been indicated by said at least one flag as not being modified from that currently being included on said node;
(c) said embedded device installing at least portions of said image file on said embedded device based upon said at least one flag as being modified and resetting portions of said embedded device based upon said at least one flag as being modified.
12 . The method of claim 11 further comprising said embedded device resetting software applications in a control plane.
13 . The method of claim 12 further comprising modifying at least one of said software applications as a result of resetting said embedded device.
14 . The method of claim 11 further comprising modifying said software dataplane as a result of resetting said embedded device.
15 . The method of claim 11 further comprising said embedded device resetting software applications in a software dataplane.
16 . The method of claim 11 further comprising a hard reset of said embedded device.
17 . The method of claim 11 further comprising a soft reset of said embedded device.
