You may be part of the crowd who is excited about the possibilities Software Defined Networking (SDN) will bring to the future. With hopes of simplifying the management capabilities of complex digital networks and their management issues, SDN is the topic du jour.

While the definition can be a little vague, SDN is simply a new way of managing networks that separates network control (intelligence) from the network plane (actual work of packet forwarding) using virtualization techniques. It’s an approach to networking that allows administrators the ability to manage network services through abstraction of higher-level functionality. SDN is the next-generation way of simplifying networking and is a big improvement from the old way of managing networks. Specifically speaking, IT teams could benefit in the following ways:

Diminished operating and hardware costs: Some network admins using SDN systems spend less money in hardware, while others have noted lower operating expenses.

Adaptability: With SDN in place, IT teams can control the whole network from a central location, which allows adjustments to be made automatically without manually remoting in to a network device.

Less Downtime: Everyone likes increased up-time and decreased downtime, and, without the need for manual intervention, potential errors are lessened.

Augmented management/planning ability: SDN manages from a single console, which provides a greater ability to simplify the planning of and setting up networks, both virtual and real.

Increased security: With hard-wired networks, it’s nearly impossible to handle increased security demands, so the SDN can now handle the stress on a company’s infrastructure caused by BYOD, new applications, and virtual machine products.

Now that your IT department is happy, what about your organization as a whole? How do they benefit from SDN?

Organizational Benefits: Specific vertical markets will benefit from SDN directly. Larger corporations like financial and insurance markets will pay more for the convenience of relying on the network for their day-to-day business. Further, SDN solutions can bring costs down. In turn, companies will have more control over the network from one single centralized console.

Education: Keeping students safe becomes easier with SDN due to real-time monitoring and more control over the configuration of devices. Additionally, SDN can improve security and lower management costs.

Government: SDN will provide administrators a better glimpse at their infrastructure’s status and allow them to identify and solve problems before they bottleneck and cause network failure.

Telecom/IT: These industries, like government, are equally complex, as their infrastructures are often spread across the country. SDN will provide an easier way to handle changes across multiple locations both quickly and centrally at a Network Operations Center.

If the above hasn’t encouraged you to reap the benefits of SDN today, don’t worry. ScanSource Catalyst is happy to help you walk through what it can mean for you and how it can positively impact your business. If you’re not part of one of the aforementioned verticals, you can still benefit, as small companies will also reap the rewards when the bigger vertical companies’ success begins to trickle down.
