A computer-implemented method of establishing a secure connection between a first application running in a first computing environment and a second application running in a second computing environment using a service mesh that: interposes a connection forming request from the first application; and establishes the secure connection in response to the connection forming request by: instructing a kernel to establishing a computing environment connection between the first and second computing environments; establishing cryptographic parameters for encrypting or decrypting application traffic between the first application and the second application; and establishing a socket with the kernel for the application traffic that will be communicated over the secure connection.

Interposing service mesh

Measures for providing timer services in a network including a cluster of nodes responsible for providing timer services to clients. At a given node in the cluster, a request to provide a timer is received from a client. Configuration of a primary replica of the requested timer on a first node in the cluster to pop after a first time has elapsed is initiated. A first timer replication message is transmitted to a second node in the cluster, the first timer replication message indicating that the second node should configure a first backup replica of the requested timer. A second timer replication message is transmitted to a third node in the cluster, the second timer replication message indicating that the third node should configure a second backup replica of the requested timer. Popping of the primary, first backup or second backup timer replicas includes initiating callback of a given client.

Timer services

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.

Virtual network function descriptor generator

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.

Deploying applications

A media gateway and method with a media session manager function, a media processor function, and a media session state datastore function. The functions are provided by one or more instantiations which allow for independent scalability of the functions in the media gateway.

Media gateway

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.

Serving a network resource usage file

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. The method comprises, at the deployment management entity: receiving a lifecycle management message relating to a deployment of VNFs; associating the received lifecycle management message with a specific deployment of VNF instances, the specific deployment comprising a set of more than one VNF instances orchestrated by a network function virtualization (NFV) orchestrator and managed by a VNF management entity, both of which are said MANO entities; updating a first VNF instance in the deployment on the basis of the received lifecycle management message; and updating a second VNF instance in the deployment on the basis of the received lifecycle management message.

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.

Data processing

A telephony signalling element and method with a signalling processing function and a session datastore function. The signalling processing function has associated functions that are provided by one or more instantiations, and the session datastore function has associated functions that are provided by one or more instantiations. The instantiations allow for independent scalability of the functions in the telephony signalling element.

Telephony signalling element

Measures, including methods, systems and computer-readable storage mediums, for use in processing notifications relating to telecommunication sessions. A cluster of servers is operable to receive incoming notifications where each server can process any given notification and update a store holding records based on previous notifications. The cluster may include a timer function to allow records to be closed when no relevant notifications are received after a timeout interval.
