Abstract: There is described a method for operating a proxy in a network function virtualization (NFV) system. The NFV system comprises a virtualized network function (VNF) manager for managing a VNF, a virtualized infrastructure manager (VIM) for managing a resource, and a NFV orchestrator. The method comprises: receiving a resource allocation request for the VIM from the VNF manager; sending the resource allocation request to a component of the VIM; receiving a response to the resource allocation request from the component of the VIM; and sending the response to the NFV orchestrator.

Abstract: There is described a method for mapping data representing an instance of a service model for a network onto policy information for controlling one or more Software Defined Network (SDN) switches in the network. The instance of a service model comprises a topology of one or more network functions and at least one virtual network function and a data flow through the topology, and the at least one virtual network function defines a dynamic flow control policy in dependence upon which data flow through the virtual network function to or from one or more of the network functions is selectively controlled. The policy information is provided to one or more SDN control entities for controlling the one or more SDN switches in the network so that data flows through the network in accordance with the service model instance.

Abstract: In one implementation, a set of path information may be retrieved from an inventory mechanism based on a service. A set of configuration information may be received from the inventory mechanism based on a network element. The network element status may be identified based on the set of configuration information.

Abstract: A telecommunications network management system is disclosed that continuously monitors compliance with a service level agreement. In a preferred embodiment, the system includes a data collector, a performance data manager, and a service level objective monitor. The data collector receives service information from one or more sources in a telecommunications network, and converts the service information into values of primary parameters in a service model. The performance data manager receives the primary parameter values from the data collector, and calculates values of secondary parameters in the service model from the primary parameter values. The parameter values are stored in a performance database. The service level objective (SLO) monitor verifies that parameter values satisfy parameter objectives, and initiates a specified action for that parameter objective if a violation is detected.

Abstract: A telecommunications network management system that continuously monitors aggregated service performance is disclosed. The system preferably employs a service model having a hierarchy of user-defined service components, each having one or more parameters. A given service may have multiple instances, each instance corresponding to a different locality. Alternatively, or in addition, the service parameters may have customer-dependent values. The system o includes a data collector component and a performance data manager component. The data collector component receives service information from one or more sources in a telecommunications network, and converts the service information into values of primary parameters of a service model. The performance data manager component calculates values of secondary parameters of the service model, and stores the parameter values in a database.
