Abstract
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.
Claims14
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, wherein said processor performs the following steps:
- (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 that includes said (i) kernel software, said (ii) hardware configuration data, and (iii) said application software to determine portions of said image file that have been indicated by at least one flag as being modified from that which is currently installed 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 which is currently installed on said node;
- (c) said node installing at least portions of said image file on said node as indicated by said at least one flag as being modified and resetting portions of said node based upon said at least one flag as being modified;
- (d) said node not installing other portions of said image file on said node that have been indicated by said at least one flag as not being modified from that which is currently installed on said node where said node receives said other portions of said image file together with said image file;
- (e) wherein said node is configured to provide services to said plurality of customer devices independently of whether any other said node is configured to provide services to said plurality of customer devices;
- (f) wherein said installing at least a portion of said image file on said node results in a service interruption to said plurality of customer devices provided by said node.
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 that includes said (i) kernel software, said (ii) hardware configuration data, and (iii) said application software to determine portions of said image file that have been indicated by at least one flag as being modified from that which is currently installed 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 which is currently installed on said node;
- (c) said embedded device installing at least portions of said image file on said embedded device as indicated by 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;
- (d) said embedded device not installing other portions of said image file on said embedded device that have been indicated by said at least one flag as not being modified from that which is currently installed on said embedded device where said embedded device receives said other portions of said image file together with said image file;
- (e) wherein said device is configured to provide services to said plurality of customer devices independently of whether any other said device is configured to provide services to said plurality of customer devices;
- (f) wherein said installing at least a portion of said image file on said device results in a service interruption to said plurality of customer devices provided by said device.
