Central to the networking revolution is software-defined networking, which allows network administrators to virtualize their networking hardware and bring added agility and cost savings.

Although Network Services of all types can benefit from SDN, one area ripe for adoption is the wide area network. SD-WAN can enable businesses to harness virtualization and reap the benefits not only of improved agility and cost, but also other massive benefits and savings. Companies like CallTower are pushing forward with SD-WAN technology and giving businesses an easy adoption path.

Here are four reasons why SD-WAN is the future of communication:

1. Transport Options

SD-WAN gives organizations true transport independence. Since the WAN is virtualized, it can take advantage of any transport protocol that is needed. This includes 3G, 4G LTE, MPLS, Internet, Ethernet, Serial or Wi-Fi. Total transport flexibility gives your organization the ability to adapt to any number of technical requirements and save money when making the change.

2. Improved Security

Unlike traditional WAN solutions, which handle security through multiple appliances at each branch office, SD-WAN can include all of these functions in-box and at lower cost. SD-WAN can integrate with a cloud web content filtering service, too, and offer malware defenses and botnet command-and-control intervention for every branch and remote devices. You can rest at ease knowing your data is safe and sound under the SD-WAN umbrella.

3. Intelligent Pathway Control

One of the most important advantages of SD-WAN is that it can provide intelligent path control that steers traffic based on application. This traffic-forwarding capability can be set in place at the centralized controller level and then pushed out to all SD-WAN devices. Policies can be based on IP addresses, application profiles, port number, quality-of-service markings, time of day, or any other number of variables. Giving your network this level of traffic freedom means that outages and throttling will reduced dramatically.

4. Automatic Provisioning

Deploying WAN systems is so last year. SD-WAN enables businesses to send SD-WAN devices to branches un-configured. The device then can download its policy, crypto certificate and keys and automatically start to learn traffic patterns. Provisioning is dramatically easier with SD-WAN.

These are just some of the benefits of SD-WAN, but there are many more. Virtualization is a revolutionary technology, and WAN networking is no exception.
