Network solutions based on the concept of Identifier-Locator separation are increasingly considered to support mobility, overlay networking for virtualization and multi-homing across heterogeneous access networks. I have 20 years of experience in overlays/virtualization and multihoming that never found the need for "Identifier-locator separation". Encapsulation subnets have always needed their own *location* names, i.e., they need *multiple locators at different scopes*. It doesn't matter if you call that sort of subnet "layer 2" (e.g., Ethernet), TRILL, LISP, or anything else (and yes, IMO, those are all *exactly* the same thing - always have been). Joe |
