Reviewer: Gyan Mishra Review result: Ready with Nits I am the assigned Gen-ART reviewer for this draft. The General Area Review Team (Gen-ART) reviews all IETF documents being processed by the IESG for the IETF Chair. Please treat these comments just like any other last call comments. For more information, please see the FAQ at <https://wiki.ietf.org/en/group/gen/GenArtFAQ>. Document: draft-ietf-detnet-ip-oam-?? Reviewer: Gyan Mishra Review Date: 2024-02-02 IETF LC End Date: 2024-02-02 IESG Telechat date: Not scheduled for a telechat Summary: This document defines the principles for using Operations, Administration, and Maintenance protocols and mechanisms in the Deterministic Networking networks with the IP data plane. The draft is well written and almost ready for publication. Major issues: None Minor issues: Should Detnet OAM over IP data plane include IOAM RFC 9378 integrated OAM where the OAM packets are sent in-situ with the data packets. Should OAM DEX postcard based telemetry described in draft below and RFC 9232 Network telemetry framework. https://datatracker.ietf.org/doc/html/draft-mb-mpls-ioam-dex-05 Nits/editorial comments: Section 3 last paragraph Most of on-demand failure detection and localization in IP networks is being done by using the Internet Control Message Protocol (ICMP) Echo Request, Echo Reply and the set of defined error messages, e.g., Destination Unreachable, with the more detailed information provided through code points. [RFC0792] and [RFC4443] define the ICMP for IPv4 and IPv6 networks, respectively. Because ICMP is another IP protocol like, for example, UDP, a DetNet node must able to associate an ICMP packet generated by the specified IP DetNet node an addressed to the another IP DetnNet node with an IP DetNet flow between this pair of endpoints. Comment on the last line or above paragraph. Technically IPv4 is protocol 4, IPv6 is protocol 41, UDP protocol 17. So all have different protocol numbers. However ICMP is part of the IP protocol suite for diagnostics and uses the same IP header to forward the packet. New Because ICMP RFC 792 is part of the IP protocol suite and uses a basic IP header, with data portion used for diagnostics, similarly UDP utilizes the IP header as well and is part of the transport layer, thereby facilitating a DETNET node that must be able to associate an ICMP packet generated by the specified IP DetNet node and addressed to the another IP DetnNet node with an IP DetNet flow between this pair of endpoints.
