However, Kazuki Tsunemoto of Macnica points out, ``Many SD-WANs are unable to perform breakout accurately once they are verified and deployed.'' Most SD-WANs use DPI-based technology to identify apps, but in that case, this cannot be determined on the first communication. For TCP apps, the first three packets have no payload information, and the first packet needs to be routed in order to breakout at the app level. If it cannot be correctly identified during the first communication, the application will be accessed through the normal route via the headquarters. After that, if subsequent communications are correctly identified and can be accessed directly from the base, the connection source changes midway through, which may result in the communications being considered unauthorized and being unable to communicate.

On the other hand, Aruba EdgeConnect SD-WAN has a unique patent-pending technology called "First PacketiQ" that can identify the application from the first packet. Machine learning learns and collects more than 300 million web domains and IP address information of more than 10,000 types of SaaS all over the world on a daily basis, and automatically updates the DB in the SD-WAN router from the cloud without restarting the OS. . Based on the latest information, it is possible to identify the application in the first packet and control the route, so it is possible to break out only the specific application with high accuracy.

Another feature is the speed of communication between bases. Macnica conducted a data transfer experiment via the Internet between Yokohama and Ohio, USA. Before and after introducing Aruba EdgeConnect SD-WAN, the amount of data was reduced by up to 99.6%, and data transfer speed was increased by more than 10 times from 4 minutes 17 seconds to 23 seconds. The mechanism is as follows. First, the SD-WAN router analyzes and compresses the contents of the packet. After that, we use proprietary technology to streamline IP protocols such as TCP/UDP and transfer them. Once transferred, a fingerprint (hash) of the data is recorded locally. In the second and subsequent data transfers, duplicate parts are automatically deleted and only the differences are sent. This high-speed function reduces the required bandwidth, allowing you to keep costs down while using existing lines.

In addition, Aruba EdgeConnect SD-WAN has a flexible licensing system. Because of the on-demand pricing system according to the amount of bandwidth required for WAN acceleration across the entire network, it is possible to flexibly allocate the required amount of high-speed bandwidth to each base. This distribution can be changed at any time from the GUI, so even if there are locations where data transfer does not occur as expected, the license fee will not be wasted.

Since entering the market in 2015, the company's products have already been adopted by more than 1,000 companies around the world. fast and accurate. The introduction of the company's products, which are simple but have powerful appeal, is likely to accelerate further in the future.
