Couple of Tutorials on ETSI NFV MANO


The premises of virtualization is to move physical network functions (PNF in hardware) into software and to design them in a way so that they can be deployed on a NFVI (Network Functions Virtualization Infrastructure, a.k.a. the cloud).

MANagement and Orchestration (MANO) is a key element of the ETSI network functions virtualization (NFV) architecture. MANO is an architectural framework that coordinates network resources for cloud-based applications and the lifecycle management of virtual network functions (VNFs) and network services. As such, it is crucial for ensuring rapid, reliable NFV deployments at scale. MANO includes the following components: the NFV orchestrator (NFVO), the VNF manager (VNFM), and the virtual infrastructure manager (VIM).

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.

NFV MANO Part 1: Overview and VNF Lifecycle Management: Uwe Rauschenbach | Rapporteur | ETSI NFV ISG covers:

  • ETSI NFV MANO Concepts
  • VNF Lifecycle Management

NFV MANO Part 2: Network Service Lifecycle Management: Jeremy Fuller | Chair, IFA WG | ETSI NFV ISG covers:
  • Network Service Lifecycle Management

If you have any better suggestions for the slides / video, please feel free to add in the comments.
