A Guide to Software Defined Networks

Considering a Software Defined Network (SDN)? Find out everything you need to know in this guide.


Software defined networking (SDN) allows network engineers to support a switching fabric across multi-vendor hardware and application-specific integrated circuits.

A network administrator can shape traffic from a centralised control console without having to touch individual switches.

SDN is also useful for maintaining service level in a cloud environment, by providing an API-enabled approach to manage the network and move workloads in a consistent way.
