Control device, resource manager and methods thereof

Abstract

The invention relates to a control device (100) and a resource manager (300). The control device (100) includes a processor (102), configured to: receive a service request (service request, SR), wherein the service request (service request, SR) includes a request associated with a network function or a network service in the communication system (500) Resource (resource, R); obtain the descriptor (descriptor, D) based on the service request (service request, SR); derive the metadata of the service availability level (service availability level, SAL) from the descriptor (descriptor, D); obtain Commissioning value (commissioning value, CV), where the commissioning value (commissioning value, CV) is associated with the needs of the business; the metadata of the commissioning value (commissioning value, CV) and the service availability level (service availability level, SAL) Mapping; and deriving the service availability level (service availability level, SAL) of the resource (resource, R) associated with the network function or network service based on the mapped commissioning value and service availability level (service availability level, SAL) metadata . The resource manager (300) includes a processor (302), configured to: receive a resource request (resource request, RR), wherein the resource request (resource request, RR) includes a resource (resource, R) service availability level (service availability level) , SAL) or the resource indication (RI) of the service availability level (service availability level, SAL) of the resource (resource, R), wherein the resource (resource, R) is related to the network function or network in the communication system (500) Service association; derivation of service availability and reliability requirement (SARR) based on service availability level (service availability level, SAL); and based on service availability level (service availability level, SAL) or resource indication (resource indication, RI) derives assigned resource (AR), where assigned resource (assigned resource, AR) corresponds to resource (resource, R) associated with network function or network service, and assigned resource (assigned resource, AR) satisfies resource ( resource, R) derived service availability and reliability requirements (service availability and reliability requirement, SARR). Furthermore, the invention also relates to a corresponding method, computer program and computer program product.

Description

technical field [0001] The present invention relates to control devices and resource managers. Furthermore, the invention also relates to a corresponding method, computer program and computer program product. Background technique [0002] The European Telecommunications Standards Institute (ETSI) defines a network function virtualization (network function virtualization, NFV) architecture framework, depicting functional blocks and reference points in the NFV framework. Architecturally, a network service can be viewed as a forwarding graph of network functions (Network Function, NF) interconnected through supporting network infrastructure. Low-level network function behavior affects higher-layer service behavior. Thus, the behavior of a network service is the composition of the behavior of its constituent functional blocks, which may include individual NFs, collections of NFs, forwarding graphs of NFs, and / or infrastructure networks. [0003] A virtualized network function...
