"The substrate allows you to build things like open-source software, other kinds of software to experiment with what makes sense, what gives you good interfaces and services for users."
Code that members contribute to OpenDaylight will be chosen solely on the basis of merit, said Inder Gopal, vice president for networking development at IBM.
"The provenance of the code doesn't matter," Gopal said in a presentation on OpenDaylight at the conference. "Once it becomes Daylight, it's Daylight code."
In answer to another question at the standing-room-only conference, ONF's Pitt said open-source software isn't the same as a standard. If one party controls the software, it may let others use and adapt the code but make unilateral changes that leave them hanging.
"If it's open, but not standard, it might be controlled by a single party," Pitt said. "Something that's standard means it's got broad community and industry agreement on what it is and on how it's used."
