What is NFV orchestration

SDN or NFV?

Software Defined Networking (SDN), Network Functions Virtualization (NFV) and Network virtualization (NV) are all complementary approaches. They each offer a new way to design and manage the network and its services:

  • SDN: separates network control and forwarding and offers a central view of the distributed network for more efficient orchestration and automation of network services.
  • NFV: focuses on optimizing the network services themselves. NFV decouples the network functions such as DNS, caching, NAT, intrusion detection, etc. from proprietary hardware devices so that they can function as software to accelerate service innovation and provisioning, in particular in service provider environments.
  • NV: Ensuring that the network can integrate and support the requirements of virtualized architectures, especially those with multiple requirements.

Similarities
SDN, NFV and NV aim to advance a software-based approach to networking for more scalable, agile and innovative networks. For example, they all aim to:

  • Move functionality to software
  • Use of deployed servers and switches instead of proprietary devices
  • Use of application program interfaces (APIs)
  • Support more efficient orchestration, virtualization and automation of network services
