摘要： Described herein is a machine-implemented method for generating a data image from a plurality of network devices, comprising: identifying a plurality of network devices each having an instance of said data image; requesting return of a portion of data and a hash tree path from each identified device of said plurality, each said hash tree path being derived starting from leaf data nodes of said data image; producing at least one compiled subtree of a hash tree from a plurality of returned said hash tree paths; verifying at least one said portion of data according to said at least one compiled subtree; and forming a data image comprising a plurality of verified said portions.

摘要： A method for constructing a delta update at a server wherein the server requests from each of a plurality of devices a portion of a software image to be used as a basis for the delta update 214-216, verifying the received portions 218 and then constructing a precursor software image based on the received portions 222. A delta update is then generated based on the constructed software image 224 which can be used to update the software of the devices 226. The devices may send a hash data structure such as a Merkle tree indicative of the received software image and the image stored at the device, the server comparing the hash data structures to identify mismatches between software images stored on the devices. The comparison can be made between three devices to identify the portion of the software image originating from a mismatched software image. If verification of a portion fails, the server may request the portion from a different device. An image size may be determined for the software image along with establishing a population number of the devices which can be used to calculate a number of target devices and a portion size to be requested.
