Managing multiple semantic versions of device configuration schemas

Abstract:

A controller device manages a plurality of network devices. The controller device includes one or more processing units implemented in circuitry and configured to maintain a graph data structure representing device level configuration schemas for the plurality of network devices, the graph data structure including trie nodes for every first device level configuration schema element for a first model of a version of network device of the plurality of network devices; obtain corresponding second device level configuration schema elements based on a path for a second model of the version of the network device; determine a deviation between the second device level configuration schema element and the first device level configuration schema; and update the trie node to add a branch to a node representing the second device level configuration schema element.
