It is a terrible, terrible language. Their should be a C driving license, and unless you're writing kernel code, you shouldn't be allowed to use it.
because it's very hard to write quality code on. Arista isn't really using C, mostly C++ and good portion of that is machine generated from their own proprietary state description language. They also heavily unit test and automate black-box testing.
Ooh, that's interesting. They've actually adopted some modern software practices. How novel!
I wish someone would do something even more novel, like create full routing suite in Erlang. But from what we have now in the market, I think Arista is most innovative.
Yeah it'd be great to move away from this low-level paradigm for NOS code to a language and runtime with better features. I guess all the IOS/JunOS devs starts to see the problem in terms of their existing solution set, when all you have is a hammer etc.
It's a shame the whitebox switching platforms don't have better control plane (as well as better hardware programming APIs, or at least some open docs). It would be interesting to experiment with some of these ideas.
