Denis is in charge of a commercial data center that handles many customers who host their servers there. He wants to be able to configure his data center network to adjust to traffic pattern changes and to manage bandwidth and other options. What technology should he implement to allow central, programmatic control of his network?

Software-defined networking (SDN) uses code to configure and control the network. This allows for agile, programmatic control and configuration as needed from a central control point. SD-WAN provides similar control for wide area network links, proxy routing occurs when a proxy server routes traffic between clients and other systems, and agile networking is not a commonly used industry term.
