1. Definition and Purpose:

MANO is an architectural framework defined by the European Telecommunications Standards Institute (ETSI) for the management and orchestration of network functions virtualization (NFV) infrastructure and network services. Its primary objectives include:

  • Lifecycle Management: This involves the onboarding, instantiation, scaling, and termination of Virtualized Network Functions (VNFs).
  • Resource Orchestration: Ensuring efficient allocation and optimization of resources like compute, storage, and network in a dynamic and automated manner.
  • Service Orchestration: Managing and orchestrating network services to meet specific performance and service level agreement (SLA) requirements.

2. Components of MANO:

The MANO framework consists of three main functional blocks:

  • NFV Orchestrator (NFVO): This is responsible for the overall orchestration of VNFs and network services. It interfaces with the Virtualized Infrastructure Manager (VIM) to allocate and manage resources.
  • Virtualized Infrastructure Manager (VIM): This component manages the NFV infrastructure (NFVI) resources, including compute, storage, and network resources. It provides APIs to the NFVO for resource allocation and management.
  • Virtualized Network Function Manager (VNFM): The VNFM is responsible for managing specific VNFs throughout their lifecycle, from instantiation to termination. It interacts with both the NFVO and VIM to ensure proper VNF lifecycle management.

3. Functions and Responsibilities:

  • Service Lifecycle Management: MANO ensures seamless deployment, scaling, and termination of services and VNFs based on demand, SLAs, and resource availability.
  • Resource Allocation and Optimization: Through automated orchestration, MANO optimizes resource utilization, ensuring efficient allocation of compute, storage, and network resources to meet performance and scalability requirements.
  • Fault Management and Healing: MANO monitors the health and performance of VNFs and services, triggering automated healing actions in case of failures or performance degradation.
  • Policy and SLA Management: MANO enforces policies and SLAs defined by service providers, ensuring that network resources and services meet predefined quality and performance criteria.

4. Integration with 5G Architecture:

In the context of 5G networks, MANO plays a pivotal role in enabling network slicing, a key feature that allows the creation of multiple virtualized network instances on a shared physical infrastructure. By orchestrating resources and services dynamically, MANO facilitates the deployment and management of diverse 5G services, including enhanced Mobile Broadband (eMBB), Ultra-Reliable Low Latency Communication (URLLC), and Massive Machine Type Communications (mMTC).

Conclusion:

MANO is a critical component in the 5G ecosystem, enabling efficient management, orchestration, and optimization of network resources and services. By automating and streamlining operations, MANO enhances agility, scalability, and performance, paving the way for innovative 5G services and applications.
