SDN的發展進入微妙階段
SDN: The 'Quiet Revolution'
Interop ITX experts say software-defined networking has evolved into a subtle agent of change.
A few years ago, everyone was talking about software-defined networking. It was going to be a massive game changer that enabled much cheaper, more efficient, and dynamic networking. These days, you don't hear nearly as much about SDN. But experts say that the technology is making inroads, just in a more low-key fashion than expected.
"Early on, SDN was envisioned as the thing that would change everything about networking. SDN controllers were going to take over the world and be the massive brains of your network," Lisa Caywood, director of ecosystem development at the Linux Foundation's OpenDaylight Project, told me in an interview. Today, vendors and users alike have come to view SDN as a tool to solve specific business problems instead of a "grand platform that will solve all ills," she said.
Companies are building solutions around and on top of open source SDN platforms, but not necessarily advertising them as SDN, Caywood said. "It enables them to do something they couldn't," she said. "So that revolution is happening, but it's a quiet revolution."
Caywood will moderate a panel at Interop ITX in May, "SDN: What Is It Good For?" The session is designed to provide practical guidance for defining and scoping an SDN project.

Slowing down the transformation of mainstream networks is the fact that networking technology is replaced much less frequently than other IT equipment: Every six to seven years compared to three to five, Hanselman noted.
