Abstract: Techniques are described for generating a virtualized network function (VNF) descriptor (VNFD) indicative of resources for managing VNF components (VNFCs) across a plurality of virtualized infrastructure managers (VIMs) implemented in a virtualized computing environment configured in a user-specific configuration. A VNFD generator receives a solution description file (SDF) encoding user input pertaining to the user-specific configuration, and a VNFC descriptor encoding VNFC specific information. The SDF and VNFC descriptor are validated and translated to generate an abstracted VNFD that is independent of renderers implemented at the virtualized computing environment. The abstracted VNFD is translated to a VNFD that is specific to the renderers and VIM and VNFD-specific information at the virtualized computing environment.

Abstract: A method for deploying an application at a cluster of cloud nodes comprises receiving a component defining the deployment of the application at the cluster of cloud nodes, the component recursively defining a first graph of other components. A component has a mapping from an interface of the component to an interface of any component referenced in the component. The method comprises compiling the received component into instructions for input to an orchestrator of the cluster of cloud nodes; and sending the instructions to the orchestrator to trigger deployment of the application.

Abstract: A method of serving a network resource usage record file is disclosed. The method can comprise: storing network resource usage records in a distributed database, the network resource usage records relating to network resource usage in a telecommunications network; sending a file list identifying a network resource usage record file over a file retrieval interface without having constructed the network resource usage record file; receiving, over the file retrieval interface, a request for the network resource usage record file; constructing, in response to the receiving of the request, the network resource usage record file, the network resource usage record file comprising one or more network resource usage records obtained from the distributed database; and serving, over the file retrieval interface, the network resource usage record file.

Abstract: Embodiments relate to virtualization and have particular application to lifecycle management of Virtualized Network Functions (VNFs). Preferred embodiments provide a method for managing VNFs in a communications network that comprises management and orchestration (MANO) entities and a deployment management entity which is functionally separate from the MANO entities.

Abstract: Data is processed in a telecommunications network. First and second notifications are received, via an input interface, from first and second Charging Trigger Functions, CTFs, in the telecommunications network. The first and second notifications relate to network resource usage in the telecommunications network. A scalable transformation function is used to transform data derived from the first and second notifications into a first usage detail report in a first detail report format and a second usage detail report in a second, different detail report format. The first and second usage detail reports are output, via an output interface, to at least one recipient system.

Abstract: A plurality of network nodes are configured to form a virtual logical network over a plurality of broadcast domains. Configuring the virtual logical network includes configuring at least one of the nodes in the plurality of nodes to broadcast routes to IP addresses hosted on nodes in the plurality of network nodes between nodes in the plurality of broadcast domains. A primary workload hosted on a first node in the plurality of nodes is configured to share ownership of an IP address with a secondary workload hosted on a second node in the plurality of nodes. In response to detecting a failure indication associated with the primary workload, an IP address failover procedure for the shared IP address is performed between the primary workload and the secondary workload.
