Abstract: A method for allocating an IP address for an instance in a NFV system includes obtaining a first requirement of IP address allocation from VNFD by a first node in the NFV system. A second requirement of IP address allocation for the instance is determined according to the first requirement. Then the second requirement is sent to a second node in the NFV system that allocates the IP address for the instance.

Abstract: A non-transitory computer-readable medium storing computer instructions for allocating an IP address for an instance in a network function virtualization (NFV) system, that when executed by one or more processors, cause the one or more processors to perform the steps of obtaining a first requirement of IP address allocation from VNFD by a first node in the NFV system, determining a second requirement of IP address allocation for the instance according to the first requirement; and sending to a second node in the NFV system the second requirement, wherein the IP address is allocated for the instance based upon the second requirement.

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.

Abstract: System and method for resource management are disclosed. These include receiving, by a virtualized network function (VNF) manger (VNFM) entity, from a network functions virtualization orchestrator (NFVO) entity a granting indication including a granting granularity in which the NFVO entity permits the VNFM entity to perform multiple VNF management operations for one or more VNFs, determining, by the VNFM entity, that a first VNF management operation is in a scope of permission based on the granting indication upon the first VNF management operation being triggered, and sending, by the VNFM entity, a first resource allocation request for the first VNF management operation to a virtual infrastructure manager (VIM) entity.
