The U.S. military must adopt a software-defined network to improve agility, flexibility and interoperability with international partners while keeping pace with technological changes, says Lt. Gen. Robert Ferrell, USA (Ret.), former Army chief information officer/G-6.
Owning every piece of hardware is no longer necessary or feasible, says the general, who retired in May. “This legacy environment that we have that is now hardware-based is not going to cut it,” he asserts.
A software-defined network offers a number of benefits, but getting there is no easy task, Gen. Ferrell indicates. “The software-defined network is the way to go, but that’s going to take some time to move in that direction,” he says.
