Hi Ron, Clearly isolation must not be undersood in strict terms, otherwise fully isolating the control from the data-plane results in a useless architecture. This is also what I understand from your comment.
This means that "isolation" must be understood as a degree, "to which degree are the control and the data-plane isolated?" As such, a "degree" is not fundamental to an architecture and -in my view- not a design principle.
