SDN - Revolutionising Large Scale Mission Critical Networking Environments
Software-defined Networking (SDN) offers the ability to implement and manage network services centrally using software to control and define equipment and services. This enables simplified management, faster provisioning, automation, programmability and many other benefits for data centres and Wide-Area Networks (WAN). However, SDN is not a silver bullet solution for all enterprises and markets, being best suited to large scale networks carrying mission-critical data. This lends itself perfectly to the telco, financial services and healthcare sectors in particular.
The main advantage of SDN is the ability to centralise network provisioning, which means that all network devices can be deployed from a single location without the need to visit each site. SDN is therefore advantageous for enterprises with multiple branches spread across geographies. In addition, all networking tools and systems can be managed from a single application, so the need for multiple software management systems is eliminated. As a result, this simplifies complexity and reduces management costs.
