Abstract

Claims (14)

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, 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.

2. The cable distribution system of claim 1 further comprising said node resetting software applications in a control plane.

3. The cable distribution system of claim 2 further comprising modifying at least one of said software applications as a result of resetting said node.

4. The cable distribution system of claim 1 further comprising modifying said software dataplane as a result of resetting said node.

5. The cable distribution system of claim 1 further comprising said node resetting software applications in a software dataplane.

6. The cable distribution system of claim 1 further comprising a hard reset of said node.

7. The cable distribution system of claim 1 further comprising a soft reset of said node.

8. 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.

9. The method of claim 8 further comprising said embedded device resetting software applications in a control plane.

10. The method of claim 9 further comprising modifying at least one of said software applications as a result of resetting said embedded device.

11. The method of claim 8 further comprising modifying said software dataplane as a result of resetting said embedded device.

12. The method of claim 8 further comprising said embedded device resetting software applications in a software dataplane.

13. The method of claim 8 further comprising a hard reset of said embedded device.

14. The method of claim 8 further comprising a soft reset of said embedded device.
