Runtime adjustment of configuration models for consistency preservation

摘要

A system performs runtime adjustment of a configuration model. The system receives, at runtime, a change request directed at one or more modified entities in the configuration model. Based on leadership information, one or more infringing entities are identified among the one or more modified entities. The leadership information indicates an impact that one entity has on another entity with respect to a given constraint. Based on the leadership information, a propagation scope is identified for a constraint violated by an infringing entity. The propagation scope includes the infringing entity and other entities that are potentially affected by the request. For resolving single constraint violation, a collection of paths are created in the propagation scope and a path is selected one at a time starting from the shortest path in the collection. For resolving multiple constraint violation, a bonded path is formed for a group of propagation scopes that overlap.
