What is Software-Defined Networking and Why Is It the Future of Networking Connections?

Too Long; Didn't Read

Software-defined networking, otherwise known as SDN, raises the technology to a new level. It offers greater speed, flexibility, and security. Traditional networking uses the routing and switching protocols to determine the best path for moving traffic. With traditional networking, the routing protocol acts as the control plane, determining the flow of traffic by sending it out through the forwarding planes in the routers to the various network interfaces. With software-defined networks, the control planes can see the entire internet from a new vantage point.
