SDN Basics: SDNCentral’s SDN Training Video Series
Here at SDNCentral, we are in the fortunate position of having an immediate view of a revolutionary time in the software defined networking (SDN) field. Incredible innovations in virtualization and automation are taking IT to places we could only have dreamed about a few years ago. The challenge facing many now is how to navigate it all.
To help you face these changes from an informed perspective, we are launching a short series of training videos, sponsored by Arista Networks, to help you get up to speed on the basics of software-defined networking. The first video in the series is an SDN primer featuring our own Roy Chua. Note that you have to be logged in (see link on top right of page) to watch the video. You can register as an SDNCentral member to access the video.
Roy begins with the absolute basics of what software-defined networking really is. With so many stakeholders defining SDN for their own purposes, we have developed a vendor-neutral definition of SDN that has four main tenets. We believe SDN provides:
- a centralized view of the overall network;
- separation of forwarding plane and control plane; and
- orchestration and automation of network services through
- open programmatic interfaces.
Roy goes over the main uses of SDN today for both service providers and data centers. For service providers, primary use cases center around service chaining; dynamic rerouting that allows large data flows to bypass bottlenecks; programmatic interfaces for end users to request instant bandwidth; and end-to-end service provisioning.
On the data center side, SDN allows administrators to slice and stretch the network, enable automation and orchestration; and more effectively provide visibility and troubleshooting (tap aggregation). As we expect many more use cases to emerge over the next couple years, Roy discusses what you can do today to lay the groundwork for the changes to come.
