SD-WAN deployment is on the rise, which means that you need to stay up to date with this technology. Many enterprises choose SD-WAN implementation because this approach comes with multiple benefits for any organization.
This solution is ideal to enhance the performance of WANs, especially when traffic becomes too high. The Software-Defined WAN Service approach can help reduce the costs and improve the transmission speed. Let’s learn more about SD-WAN technology.
How does it work?
One of the best things about SD-WAN technology is the fact that it comes with all the advantages of software-defined networking, but it brings them in a wide area network context. The services delivery is improved and the total costs are lowered.
Software-Defined WAN manages to respond to network conditions in real time. In order to do that it uses all the data available, such as jitter, packet loss, availability and latency. It is also possible to integrate a SD-WAN into the organization WAN hat is already there.
Lower costs
MPLS connections are usually more expensive compared to internet links, so SD-WAN technology manages to be cost effective. That is because it does not require extensive provisioning time and contracts are not expensive.
Secure
The security of the network can also benefit from SD-WAN technology and that is because WAN traffic becomes encrypted when it is moved to another location. Additionally, since the network is segmented, there will be less damage during a breach. Attacks will also be detected faster because traffic becomes visible at all times.
Enhanced performance
You will also notice performance improvements when you use SD-WAN technology. For example, the backhaul penalties that come with MPLS networks are no longer there. Automation is also enabled which makes IT more efficient.
Using a SD-WAN router allowed you to combine the bandwidth of several WAN connections. In addition to that, you can also manage those WAN connections, and you can add them or remove them based on your needs.
Another advantage is that you can combined fixed-line connections and cellular connections. If you need to adjust bandwidth that is also possible under a SD-WAN implementation, which means that you can add it or reduce it as needed. Finally, you no longer need an IT team to deploy WAN services to a remote site, as this technology can handle it.
The reliability of SD-WAN
Ordering multiple internet links from various providers is usually the organizations’ solution when they move to SD-WAN. By doing this, if a link fails, the four nines availability remains. That is because here is a possibility for internet uplinks to fail, while MPLS networks, on the other hand, come with packet delivery that is highly reliable.
