SDN integrated NFV architecture: Fully automated and seamless Transport solution for 5G

NFV refers to the virtualization of network components, while SDN refers to a network architecture that injects automation and programmability into the network by decoupling network control and forwarding functions. In other words, NFV virtualizes network infrastructure and SDN centralizes network control. Combined, SDN and NFV create a network that is built, operated, and managed by software.

SDN vs. NFV: Similarities and differences

The core similarity between SDN and NFV is that they both use network abstraction. SDN seeks to separate network control functions from network forwarding functions, while NFV seeks to abstract network forwarding and other networking functions from the hardware on which it runs. Thus, both depend heavily on virtualization to enable network design and infrastructure to be abstracted in software and then implemented by underlying software across hardware platforms and devices.

SDN and NFV differ in how they separate functions and abstract resources. SDN abstracts physical networking resources -switches, routers and so on — and moves decision making to a virtual network control plane. In this approach, the control plane decides where to send traffic, while the hardware continues to direct and handle the traffic. NFV aims to virtualize all physical network resources beneath a hypervisor, which allows the network to grow without the addition of more devices.

Brief of SDN and NFV

While both SDN and NFV make networking architectures more flexible and dynamic, they perform different roles in defining those architectures and the infrastructure they support.

Finally, conventional networks must adhere to the product cycles and proprietary interfaces typical in vendor-specific environments. Ultimately, SDN rests on the notion that network control can be divorced from network infrastructure and physical devices. By applying programming and automation to network control, network operators can define, manage and manipulate logical networks directly and dynamically.

NFV, is all about the network functions that must be performed at all levels and stages of a network — at the periphery, boundary and core — to accept, forward, shape and filter network traffic as it courses through any given infrastructure.
