Abstract: Systems and methods are disclosed for resource management by a network functions virtualization orchestrator (NFVO). These systems and methods include embodiments whereby a NFVO obtains requirements for a network service lifecycle management (LCM) operation, determines a delegating granting decision for a virtualized network function (VNF) manager (VNFM) associated with the network service LCM operation in accordance with the requirements for the network service LCM operation that grants a permission for the VNFM to perform multiple VNF LCM operations under one or more constraints, and sends the delegating granting decision to the VNFM.

Abstract: A virtualized network function (VNF) life cycle management (LCM) method is disclosed that includes sending, by a virtualized network function manager (VNFM), a grant request for a VNF LCM operation to a network functions virtualization orchestrator (NFVO), wherein the grant request comprises a requested wide area network (WAN) connectivity requirement for connecting multiple sites that virtualized network function components (VNFCs) of the virtualized network function (VNF) instance are placed in, and the VNF comprises at least two VNFCs placed in different sites. In this embodiment the method also includes receiving, by the VNFM, a grant response from the network functions virtualization orchestrator (NFVO), wherein the grant response comprises WAN Infrastructure Manager (WIM) information and a granted WAN connectivity requirement approved by the NFVO.
