摘要： A Network Service Descriptor (NSD) is generated, from Virtualized Network Functions (VNFs) existing in a VNF catalog, for instantiating a network service which satisfies given network service requirements. From the VNF catalog, a system selects VNFs that provide functionalities and architectural blocks required to fulfill the NS requirements. The system generates at least a VNF forwarding graph (VNFFG), which includes relations between the functionalities and the architectural blocks of the selected VNFs as well as traffic flows between the selected VNFs. The system then creates the NSD, which includes the VNFFG, for instantiating the network service.

摘要： A non-transitory computer readable media, methods, system and network function virtualization orchestrator can be used to instantiate a network service operating as at least a portion of a network slice. A network service descriptor describing the network service comprises at least one service deployment flavor; zero or more sharing allowed attribute defining if the network service or constituent instances of the network service is allowed to be shared with another network service instance, or with its constituent instances; and zero or more external placement rule attribute defining if the network service or constituent instances of the network service, is affine or anti-affine with current and future other network service or constituent instances of the current and future other network service.

摘要： Resources in an Infrastructure-as-a-Service (IaaS) system are upgraded in an iterative process. In response to an upgrade request indicating requested changes to a current configuration of the system, one or more graph representations of the current configuration and the requested changes are created. The graph representations include a control graph which has vertices representing resource groups, and edges representing dependences among the resource groups. A batch of resource groups is identified to be upgraded in a current iteration based on the dependencies and Service Level Agreement (SLA) requirements including availability and elasticity of the system. Upgrade operations are executed on the identified batch using selected upgrade methods which handle potential incompatibilities during transition of system configurations. The graph representations are updated to include any new requested changes and recovery operations in response to feedback of failed upgrade operations. The iterative process proceed to upgrade remaining one or more resource groups.

摘要： An upgrade campaign is generated for entities of a system described by a source configuration. According to the upgrade campaign, the system is upgraded to a target configuration using available software. A change model describes changes from the source configuration to the target configuration. According to the change model, an upgrade campaign specification model is generated, which contains at least one upgrade campaign element for each change in the change model. A subset of upgrade campaign elements are matched based on a first set of rules, and the matched upgrade campaign elements are merged into an upgrade procedure in the upgrade campaign specification model. The upgrade procedures are ordered based on a second set of rules and dependencies among the entities of the system, where the dependencies are extracted from the source configuration, the target configuration and the description of available software.
