摘要： A Software Defined Network (SDN) comprises a plurality of resources including Network Elements (NEs) and network links connecting the NEs. A method comprises receiving a request to provision an SDN Datapath in the SDN. The request comprises performance metrics for the SDN Datapath and a geographic constraint to be applied to resources used in provisioning the SDN Datapath. The method further comprises assembling a candidate set of resources to provision the SDN Datapath and initiating provision of the SDN Datapath using resources selected from the candidate set. Assembling a candidate set of resources to provision the SDN Datapath comprises obtaining a geographic location attribute of resources in the SDN and populating the candidate set with those resources having a geographic location attribute satisfying the received geographic constraint.

摘要： A method for monitoring operation of a network service for the purpose of licensing control in a virtual network environment managed by a Network Functions Virtualisation Management and Orchestration, NFV-MANO, system, is disclosed. The method comprises: defining (202) the network service in a Network Service Descriptor and deploying the network service using at least one Virtual Network Function instance identified in said Network Service Descriptor by instantiating (204) at least one Virtual Network Function Component defined by a Virtualisation Deployment Unit, wherein said Virtualisation Deployment Unit is associated with said Virtual Network Function. The method also comprises recording (206) in a first information field associated with the Network Service Descriptor information indicative of usage of the at least one instantiated Virtual Network Function Component and maintaining (208) a licensing database for storing information indicative of usage of the at least one instantiated Virtual Network Function Component based on records in the first information field.

摘要： Managing a communications network involves allocating hosts (100) for instances (105) of a virtual network function component (155). From a request to allocate, a number N is obtained indicating a minimum number of the instances to be available, and a number M indicating how many additional instances are to be allocated. If the allocations are requested to be to different hosts (anti affinity) and if the sharing of the instances by the virtual network function component can be adapted in the event of unavailability, then allocating is carried out automatically (230) of N+M of the instances to less than N+M of the hosts, so that if any one of the allocated hosts becomes unavailable there are sufficient hosts so that the virtual network function component can still be shared across at least N of the instances. Fewer hosts are needed, saving costs.
