Many large businesses and educational institutions use wide area networks (WANs) as an internal connection between devices and servers. These interconnected computers and systems do not have to be in the same building or even the same city. WANs are used for communication and sharing of information but they can be hugely complicated to run.
This is where a software-defined wide area network (SD-WAN) comes in. An SD-WAN simplifies the management and operation of a business network by using centralised software to intelligently control the traffic across the network. It is also easier to set up and cheaper to run than traditional WANs. Find a reputable company that offers SD-WAN solutions.
Why use software to control an SD-WAN?
By using software to segment, direct and control network traffic, it maximises the efficiency of the network by minimising delays and congestion. The software ensures that the entire bandwidth of the network is being used when there is a large volume of users. In addition to the efficiency advantages, SD-WAN also has security benefits.
The software can be pre-programmed with advanced security features, which gives users secure access to cloud-based applications and programmes. This allows employees or network users to remain protected against viruses, spyware, spam and other cyber threats while they work. It protects the institution’s data and prevents targeted attacks on the network.
Other advantages of SD-WAN
SD-WAN has the ability to manage multiple internet connections at the same time. It doesn’t matter whether users are connected via ADSL, 3G, 4G or fibre – the software will seamlessly connect users to the network. This simplifies and streamlines connectivity and offers a cost-effective approach to networking
Users will be able to share data, access documents and work on joint projects, no matter the type of internet connection. Data, audio, video and project files can be shared within the network with greater ease and at a lower cost. The software will automatically manage the policy, security and networking processes, leaving users free to focus on their own tasks.
Since many large businesses and institutions have remote offices or campuses, the SD-WAN will be able to support connectivity through virtual private networks (VPNs). It is also compatible with third-party services and internal security software, such as firewalls and web gateways. This ensures that all users have seamless and continuous access to the network and important data.
