The Crucial Role of Software-Defined Networking in the Internet of Things

June 16, 2015

Is it difficult for you to picture the Internet of Things (or IoT) working as quickly and efficiently as it needs to with all of the routers, firewalls, redirects, and such needed to provide solid data gathering for analytics and realistic security measures? Using standard hardware, the IoT might never come to fruition. But with Software-Defined Networking (SDN), the IoT can indeed become a reality.

In order to leverage the true potential of the IoT, you have to think beyond smartphones and computers and provide access to home appliances, business machines, vehicles, wearables, and more.
SDN virtualizes the components and services within a network, lowering latency and reducing the need for hardware. As devices and users pour into the IoT, SDN could become the gateway that allows it to happen, as well as the lock that allows it to remain secure.

SDN Can Manage the Various Devices Within the IoT

SDN is a method for centralizing control of the network and devices, while allowing the network to be extremely flexible. Using automated policy-based control, it allows for seamless access via any device or platform, while constantly authenticating devices and users and scanning for potential threats. The virtualized environment offered by SDN means that the network is accessible to any size device, any type of interface, and all types of users.

SDN Can Secure Networks in the IoT

SDN automatically configures the network devices, collecting the data necessary for analytics while keeping the details of the device's underlying infrastructure private. It is designed to authenticate devices and users and to follow prescribed access rules. SDN greatly simplifies network provisioning and is capable of remediating incoming security threats as they happen, allowing for a seamless user experience on any device, operating system, browser, or other platform.

SDN Can Provide the Flexibility Necessary to Manage the IoT

SDN virtualizes and automates network access so that the experience happens in real time.

One of the biggest challenges network administrators face with the IoT is the ability to collect data and conduct analytics to produce a positive user experience on the fly. SDN does this much faster and better than hardware based network components. SDN is capable of redirecting traffic automatically when necessary, significantly speeding up the process. SCN can also provision the environment where analytics are conducted so that insights from the data are delivered instantaneously.

With SDN, network troubleshooting is done mostly automatically. Virtualization also allows organizations to provide the power of the IoT far cheaper than it would be possible in a hardware-based network.

Is your organization poised to take advantage of the potential of the IoT? Without SDN, it would be extremely difficult or perhaps impossible to leverage the vast number of devices and users on the IoT.
