The SD-WAN represents the most modern in link aggregation with application intelligence. We are talking about a new technology that came to replace the MPLS network, which is private, and works Over the TOP by managing to aggregate several links from several different telecoms working with application performance with more quality and speed. Many businesses benefit from this system-mainly companies that work with digital data need high performance, such as companies that work with credit card transactions. A good example of the application of the SD-WAN system can be perceived when a person is paying with a card and needs to wait a while to perform the action. SD-WAN can measure the speed for information to arrive at the card operator. A supermarket that has its own card, for example, needs the SD-WAN system because only this technology can accelerate the speed between the time when the card is passed by managing to identify the best path between the card operator and the The Market box terminal. Another well-visible example is videoconferences that make the best of their speed – so much so that in the United States there are many medical videoconferences, with surgeries done in real time, using the SD-WAN technology in the transmission. For apps, SD-WAN directs policy-based traffic per application. The technology uses this link and can measure the best path, where there is less latency. The technology came to replace what we call the MPLS network, because the value is very close to the SD-WAN but with the difference that it is possible to use fixed IPs and work with the branches in broadband, applying the technology that does all this checking. SD-WAN works with different telecoms in any carrier, independently.
