NFVI stands for Network Functions Virtualization Infrastructure. It is the foundation for a virtualized network and serves as the environment in which virtualized network functions (VNFs) run. Ericsson, as a leading telecommunications company, offers solutions related to NFVI to enable operators to deploy and manage virtualized network services more efficiently.

Let's break down NFVI and its technical components:

1. Components of NFVI:

a. Compute:

This includes the servers, hypervisors, and other related components that host and manage virtual machines (VMs) or containers.

  • Servers: These are physical machines with CPUs, memory, storage, and network interfaces.
  • Hypervisors: Software that allows multiple VMs to run on a single physical server, ensuring isolation between VMs. Examples include VMware's ESXi, KVM, and Microsoft's Hyper-V.

b. Networking:

NFVI requires advanced networking capabilities to ensure that virtualized network functions can communicate efficiently and securely.

  • Virtual Switches: These are software-based switches that allow for traffic routing between VMs and between VMs and the physical network.
  • SDN Controllers: Software-Defined Networking controllers manage the network and ensure optimal traffic flow, flexibility, and scalability.
  • Network Functions: Virtualized versions of traditional network appliances, such as firewalls, load balancers, and routers.

c. Storage:

Storage solutions that provide scalable and resilient storage for VMs and their associated data.

  • Storage Area Networks (SAN): High-speed networks that provide block-level storage for VMs.
  • Network-Attached Storage (NAS): File-level storage solutions that can be accessed over a network.

2. Ericsson's NFVI Solutions:

When Ericsson provides NFVI solutions, it encompasses hardware and software components tailored for telecommunications operators. Their solutions aim to deliver:

  • High Performance: Ensuring that the virtualized network functions can meet the stringent performance requirements of telecom services, such as low latency and high throughput.
  • Reliability and Availability: Building redundancy, failover mechanisms, and high availability features to ensure uninterrupted service.
  • Scalability: Designing the NFVI to scale horizontally (adding more resources) or vertically (increasing resource capacity) based on demand.
  • Management and Orchestration: Providing tools and platforms to manage, orchestrate, and automate the deployment, scaling, and lifecycle management of VNFs.

3. Benefits of Ericsson's NFVI:

  • Cost Efficiency: By virtualizing network functions and using standardized hardware, operators can achieve cost savings in terms of hardware procurement, maintenance, and energy consumption.
  • Agility: Operators can quickly deploy new services, scale resources up or down based on demand, and adapt to changing network requirements.
  • Innovation: With a virtualized infrastructure, operators can introduce new services, features, and applications more rapidly without significant hardware changes.

NFVI from Ericsson provides a comprehensive solution for telecom operators to transition from traditional, hardware-centric networks to flexible, scalable, and efficient virtualized environments. By leveraging NFVI, operators can meet the evolving demands of modern telecommunications while optimizing costs and enhancing service delivery.
