The Pervasive Openness of NFV

Open can mean different things to different people in the context of NFV, but it plays a very significant role.

My sense is that network operators are keen to avoid any kind of vendor lock-in, particularly in the infrastructure. So open source is playing a strong role there.

Also, there are lots of open source building blocks that can be used to construct NFV infrastructure. There’s no fundamental reason to employ a bunch of proprietary technology in the infrastructure. I think that network operators accept that there’s going to be a lot of proprietary software in the virtualized network functions, but that proprietary software will run over this open environment.

And of course, that openness also extends to commercial relationships and the willingness to work with a much wider range of vendors than they have in the past. Network operators see much less risk in deploying a VNF from a smaller vendor because it’s just software. The qualification process is much less, the capex risk is much less, and it’s much easier to experiment, prototype and just try stuff out in a pure software environment.
