There’s open, then there’s open. At least that seems to be the case with network technology. Maybe it’s the popularity and impact of open-source software, or maybe it’s just that the word “open” makes you think of being wild, happy, and free—whatever it is, the concept of openness in networking is catching on. Which means, of course, that the definition is getting fuzzier every day.
When I talk with enterprises, they seem to think that openness in networking is the opposite of proprietary, which they then define is a technology for which there is a single source.
