Hi, OPS-DIR, Authors,

I have reviewed this document as part of the Operational directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written with the intent of improving the operational aspects of the IETF drafts. Comments that are not addressed in last call may be included in AD reviews during the IESG review. Document editors and WG chairs should treat these comments just like any other last call comments.

This Standards Track document describes the Home Networking Control Protocol (HNCP), an extensible configuration protocol and a set of requirements for home network devices. HNCP is described as a profile of and   extension to the Distributed Node Consensus Protocol (DNCP), which is another document in progress. This document is well written. I don't see any major issues from the operations and management perspective. It is almost ready to be published.

I have some comments as follow:

1. HNCP describes Prefix and Naming configuration. But it is not very clear how they are matched in the DNCP architecture. It would be help to understand if some description using DNCP architecture, like node state and network state, etc., could be added.
2. It would be very useful to add a bootstrap and configuration procedure of HNCP. So far, this is not clear.
3. Section 6.5 "only the one published by the node with the highest node identifier". It is not very clear how to compare the value against node identifier.
4. Section 1.1 "Ideally, the routing protocol is also zero-configuration (e.g., no need to configure identifiers or metrics) although HNCP can be used also with a manually configured routing protocol." It is not very clear how or what routing protocol is zero configuration. My guess is this refers to RFC 7503 "OSPFv3 Auto-Configuration" and ongoing work of draft-liu-isis-auto-conf "ISIS Auto-Configuration". Informational references to them should be added.

Regards,

Sheng
