Patent ID: 10931525

Abstract:
A Network Functions Virtualisation Management and Orchestration system, NFV-MANO, for managing resources in a Network Function Virtualisation Infrastructure, NFVI, has elements (NFVO, VNFM) for orchestrating and managing virtual resources to provide a network service and has an allocation element (VIM) for managing an allocation of physical resources for the virtual resources. One of the elements for orchestrating (NFVO, VNFM), obtains (210) information about which of the virtual resources could be affected by a planned adjustment of the allocation, and determines an impact (220) of the planned adjustment on a network service, based on this information. An indication based on the impact on the network service is sent (230) to the allocation element (VIM), which implements the planned allocation according to the indication. This can help enable a better trade off between allocation efficiency and quality of network service.
