NFV MANO is broken up into three functional blocks:
- NFV Orchestrator: Responsible for onboarding of new network services (NS) and virtual network function (VNF) packages; NS lifecycle management; global resource management; validation and authorization of network functions virtualization infrastructure (NFVI) resource requests.
- VNF Manager: Oversees lifecycle management of VNF instances; fills the coordination and adaptation role for configuration and event reporting between NFV infrastructure (NFVI) and Element/Network Management Systems.
- Virtualized Infrastructure Manager (VIM): Controls and manages the NFVI compute, storage, and network resources.
For the NFV MANO architecture to work properly and effectively, it must be integrated with open application program interfaces (APIs) in the existing systems. The MANO layer works with templates for standard VNFs and gives users the power to pick and choose from existing NFVI resources to deploy their platform or element.
Couple of good old tutorials, good as gold, explaining the ETSI NFV MANO concept. The videos are embedded below. The slides from the video are probably not available but there are other slides from ETSI here. If you are new to this, this is a good presentation to start with.
