SD-WAN Services from Top Telecom Companies A network that supports various communications and systems by connecting the country, society, companies, and lifestyles in real time. On the other hand, with the advancement of cloud and big data, IT has become required to be flexible enough to respond quickly to changes in the environment, and to be efficient when necessary when needed. . In some cases, conventional network systems are not suitable for meeting such IT needs, and network constraints have created barriers to building an ideal ICT system. “SDN (Software-Defined Networking)” is expected to be a solution to these issues. As an easy-to-understand example, if you enter a destination, SDN can be used as a means to realize convenience like a car navigation system that avoids traffic jams and directs the optimal route according to changes in the situation, using the ICT system. Is attracting attention. Can the ICT system realize the convenience of a car navigation system? Expanding What is SDN (Software-Defined Networking) SDN is a new concept of dynamically controlling a network with software and its architecture. In the current network mechanism, when sending data to a destination, each network device individually decides what route or rule is used to send the data through the complicated network, and the data is transferred in a bucket relay format. We are delivering. For this reason, it was difficult to change to the optimal route according to the data congestion status and the enhancement / maintenance status of some networks. In addition, network construction and changes require a large amount of device settings, which is very time consuming. Therefore, the network control and data transfer processing that has been conventionally performed by each individual network device are separated, and communication is performed by dynamically controlling the device that performs only the data transfer processing with the software on the general-purpose server side. SDN was conceived to be flexible, efficient and safe. Read More; https://www.fieldengineer.com/sd-wan/what-is-sd-wan#deploy-sd-wan |
