Abstract: A device for version management of a plurality of entity instances includes a processor configured to read an entity model and a versioning model from a storage, where the entity model describes a plurality of entities and a relationship of each entity in the plurality of entities, and where the versioning model describes a relationship for versioning of entities in the entity model, generate an instance versioning model, based on the entity model and the versioning model, where the instance versioning model describes a relationship of a first entity instance and a second entity instance, assign, in case of a version change of the first entity instance or the second entity instance, a new version to the first entity instance, based on the instance versioning model, and store the new version in the storage.

Abstract: A resource management system for managing resources in a computing and/or communications resource infrastructure is disclosed. The system comprises a database for storing a model of the resource infrastructure. The database defines a set of resources provided by the infrastructure; a set of software applications operating within the infrastructure and utilizing resources; and associations between given applications in the model and given resources to indicate utilization of the given resources by the given applications. The model can be used to perform resource utilization analysis and failure impact analysis.

Abstract: A method of configuring a telecommunications system to provide a service involving multiple devices is disclosed. The method includes receiving a configuration script specifying a sequence of configuration instructions for configuring at least two of the devices to provide the service, and concurrently executing an instance of the configuration script for each of the at least two devices to configure the at least two devices to provide the service. The method can be used as part of a network management system or service provisioning system.
