摘要： A persistent version-controlled is provided the enables automated configuration of VNFs/CNFs following deployment or re-deployment of VNF/CNF instances throughout the life cycle of the VNFs/CNFs. Immutable copies of NF configurations for a VNF/CNF are stored in the version controlled data storage 100. Multiple versions of a NF configuration can be associated with a common configuration reference (e.g., URL). Metadata associated with the different versions of a NF configuration indicates which of two or more different versions is the current version. The collection of different versions of a NF configuration associated with the same stable reference provide a complete history of the NF configuration, thus allowing rollback to any previous version of the NF configuration by simply modifying the metadata to mark that version as the current version. If a VNF/CNF needs to be re-deployed, the same configuration reference used during the initial deployment is used to download the most recent version of the NF configuration based on the metadata.

摘要： A computer-implemented method (300) of operating a telecommunications network (110-1), said telecommunications network comprising a plurality of nodes (150), and the method comprising the steps of: storing: a set of historic reconfiguration instructions, said instructions having been used to reconfigure the telecommunications network; first status information from each of the plurality of nodes, wherein said first status information is received prior to reconfiguring the telecommunications network according to a given historic reconfiguration instruction; and second status information from each of the plurality of nodes, wherein said second status information is received after reconfiguring the telecommunications network according to the given historic reconfiguration instruction; receiving a new reconfiguration instruction (310); prior to reconfiguring the telecommunications network according to the new reconfiguration instruction, identifying from the set a similar historic reconfiguration instruction having a similarity to the new reconfiguration instruction within a tolerance threshold; comparing the first and the second status information associated with the identified similar historic reconfiguration instruction so as to determine whether the identified similar historic reconfiguration instruction resulted in a detrimental effect to performance of the telecommunications network; in dependence on whether the identified similar historic reconfiguration instruction resulted in a detrimental effect, calculating a success confidence metric for the new reconfiguration instruction, said metric representing a probability that a reconfiguration instruction does not result in a detrimental effect to performance of the telecommunications network (320); and if the success confidence metric is: greater than a predetermined threshold value, reconfiguring the telecommunications network according to the new reconfiguration instruction (350); or less than a predetermined threshold value, preventing reconfiguration of the telecommunications network according to the new reconfiguration instruction (360).

摘要： A system may include a central computational instance configured to provide a service to a plurality of computational instances, wherein the service is associated with configurations respectively corresponding to the computational instances. The system may also include a computational instance dedicated to a managed network and storing a synchronization history specifying information that was synchronized between the computational instance and the central computational instance. One or more processors may be configured to: (i) receive a configuration of the service into the computational instance, wherein the configuration was received from a non-production computational instance of the plurality of computational instances; (ii) read, from the configuration, a synchronization identifier; (iii) determine that the synchronization identifier does not exist in the synchronization history; and (iv) in response to determining that the synchronization identifier does not exist in the synchronization history, transmit the configuration to the service provided by the central computational instance.
