A delta file may be assembled for use in updating software on a networked device. The delta file may include at least one manifest, and each manifest may be associated with a subset of files (e.g., replacement and/or upgrade files for the networked device). The subset(s) of files may be selected based on a wide range of criteria. In an example, subsets may be selected based on rules that regulate when files are allowed to change. Subsets may also be defined based on the device associated with the files (e.g., a metrology device or a communications device). Any desired criteria/criterion may be used to define a subset of files. The delta file may be transmitted to the networked device. On the networked device, the subset(s) of files may be verified against data corruption, actions of bad actors, and/or unexpected changes at runtime.

System subset version and authentication for remotely connected devices

A system set of a utility node device, such as a kernel and/or root file system, may be updated by utilizing a multi-system set configuration. For example, the multi-system set configuration may include a first system set that is generally configured to act as an 'active' set, a second system set (e.g., 'idle' set) that is configured to operate when the first system set is non-operational or in an &#x201c;idle&#x201d; state, and a third system set that is configured to operate when the first and second system sets are non-operational. During an update of a system set, an update package may be applied to the second &#x201c;idle&#x201d; system set, while the first &#x201c;active&#x201d; system set remains operational. The utility node device may comprise a smart utility meter, sensor, control device, transformer, switch, relay, or the like.

Utilizing a multi-system set configuration to update a utility node system set

Software and/or firmware of a utility node device may be updated by utilizing an update package that includes multiple update items related to different types of the software and/or firmware. The utility node device may selectively install one or more of the multiple update items based on a type of the software and/or firmware that is currently installed on the device. The different types of software and/or firmware may relate to different versions of the software and/or firmware and/or different types of hardware. In some instances, an update item of the update package comprises a delta file that contains differences between different versions of the software and/or firmware. The utility node device may comprise a smart utility meter, sensor, control device, transformer, switch, relay, or the like.

Utility node software/firmware update through a multi-type package

Disclosed are apparatus and methodology subject matters for upgrading firmware associated with one or more metrology devices and adjunct devices. Methods are disclosed for broadcast transmission of portions of a firmware image file from an originating device over a network connecting multiple devices to be upgraded. The entire image file may be transmitted as segments to be assembled by the end devices. Broadcast segments not properly received from the originating device may be retried directly from the originating device or from neighbors correctly receiving the segment. A viral propagation methodology is disclosed as an alternative to portions of the broadcast methodology.
