Advanced Network Function Virtualization (NFV) Orchestration
description Advanced Network Function Virtualization (NFV) Orchestration Overview
Automating the deployment, scaling, and chaining of virtualized network functions (VNFs) like firewalls, load balancers, and DPI engines across a Software-Defined Network (SDN) fabric. This requires integrating orchestration tools (like MANO) with underlying cloud infrastructure APIs. It moves network management from physical boxes to software workflows.
insights Why this score
Advanced Network Function Virtualization (NFV) Orchestration ranks #4 of 6 in the Cloud ranking, behind Cloudinary, ahead of Rackspace Managed Disaster Recovery.
help Advanced Network Function Virtualization (NFV) Orchestration FAQ
What is the ETSI NFV MANO architecture?
The ETSI NFV MANO (Management and Orchestration) framework is an architectural standard used to manage virtualized network functions and their underlying infrastructure. It provides a structured way to automate the deployment, scaling, and lifecycle of VNFs across an SDN fabric.
How do NFV orchestration tools handle scaling during traffic spikes?
Orchestration platforms like OpenStack or Kubernetes monitor network metrics and automatically spin up additional instances of VNFs, such as load balancers, when traffic spikes occur. Once the peak subsides, the orchestrator gracefully tears down the excess instances to save resources.
What is the difference between SDN and NFV?
SDN (Software-Defined Networking) separates the control plane from the data plane to centrally route traffic, whereas NFV decouples network functions from proprietary hardware appliances. Orchestration often integrates both, using SDN to connect virtualized firewalls and DPI engines deployed via NFV.
Which tools are commonly used to chain virtualized network functions?
Tools like OSM (Open Source MANO) or commercial platforms like Cisco Elastic Services Controller are heavily used to define and deploy Service Function Chaining. These tools ensure that traffic passes sequentially through virtualized firewalls, NATs, and DPI engines in the correct order.
