What is Software Defined Networking (SDN)?

by Iwan Price-Evans on Networking • May 10, 2022

What is software defined networking (SDN), and how might it affect your business? This article will explain the basics of this new technology and its potential impact on businesses.

The Data Plane

In traditional networking, the control plane manages the flow of packets through the network while the data plane handles packet forwarding. With SDN, the two planes are separated so that the control plane can manage the entire network, rather than just individual devices.

The Control Plane

The control plane is responsible for managing the network infrastructure, such as routers, switches, and other network equipment. It also provides the intelligence needed to make decisions about how to route traffic throughout the network.

The Challenges of SDN

SDN has been touted as a solution to some of the challenges facing IT organizations today. However, there are still several barriers to adoption. One of the biggest issues with SDN is that it requires new skillsets and changes to existing processes.

The Benefits of SDN

SDN offers benefits such as improved scalability, reduced complexity, and increased security. It also provides better visibility into network performance and enables faster troubleshooting.
