Network Virtualisation and visibility of the lower layers

This isn’t much of the blog post, but more of a link to a fairly solid discussion that’s happening in the comments section of a blog post @jonisick recently wrote:

What Network Virtualization Isn’t

The premise of the discussion I think boils down to a bit of a disconnect in points of view of the proponents of Network Virtualisation and those who are trying to understand what introducing NV into their traditional switched/routed DC network environments will do to the operational complexity.

Anyway, head over to the Joe’s blog linked above for the full scoop, and don’t miss the comments.

TL;DR for the impatient: I believe that we need to sort out some kind of OAM at the points where NV platform consumes underlay IP transport services. I don’t know how it is going to shape up, but believe that this is a very important point that deserves a lot more attention than I’ve seen so far.
