Hi Daniele, [Operator hat on.] I agree on several things you wrote, starting from the answer to Jon's rhetorical question, which cares more about how much (at least I've never noticed my co-chair has a short memory). Nevertheless the sentence below needs to be corrected, because it happens to be wrong: "optical networks with no control plane" is as inaccurate as "a fuel car with no battery". Not relying on the high-end version of this mean to realize the core task of an equipment must not hide that most (even those Sonet/SDH ADMs) of the deployed optical devices do (mostly for management traffic, whose fate PCEP may share)...: - perform IP forwarding, - have a routing table, - run an IGP to populate that routing table, - run an IGP to advertise their attached addresses, - support a large set of (IP-based) protocols for various purposes (e.g., ICMP, DHCP, SSH, SMTP), i.e. squeezing many roles within a single protocol is a non-goal. A possible rephrasing could be "networks where the control plane is limited to background tasks", which reminds that operators deploy "fully packaged cars", not just "raw wheels with a motor" according to the misleading scope assumed in the current discussion.
