[c-nsp] [External] SDx open standard?

[Alex K.]

That's what I'm asking about.

While the thread Mark referenced, deals (in my humble opinion) primarily
with automation side of things, my question is how the whole SDN thing
became vendor-specific-closed-protocol?

I'm not talking specifically about any particular facet of SDN, such as
automation or forwarding plane control over the network (though l
personally most interested in the latter, at least for now) or anything
else - rather, how 100% of solutions I've been presented over past year or
so, are all closed code-proprietary protocol solutions?

Not a single one was based on an open standard, such as Open Flow, not a
single one is able to interoperate with others, though one particular SDN
solution will cost *a third *same vendor "traditional" standard compliant
equipment. That's for me, was begging the question - am I missing something
here and I'm really be better off by selling my soul to a single vendor for
eternity, rather than opting for standard compliant box? If there's such
one to begin with?

Best regards.
