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 <http://wiki.tools.ietf.org/area/gen/trac/wiki/GenArtfaq>. Document: draft-allan-5g-fmc-encapsulation-04 Reviewer: Russ Housley Review Date: 2020-07-03 IETF LC End Date: 2020-07-27 IESG Telechat date: Unknown Summary: Almost Ready Major Concerns: Section 2 says: PPPoE data packet encapsulation is indicated in an IEEE 802[8] Ethernet frame by an Ethertype of 0x8864. This is very odd way to introduce this section. IEEE Std 802-2001 covers the architecture for Project 802, not just Ethernet frames, which are fully specified in IEEE 802.3. However, the MAC frame, MAC addresses, and Ethertypes are all described in this standard. Second, you need to point to RFC 2516 to talk about PPPoE. Third, the Ethertype is not defined in IEEE Std 802-2001. I suggest: The Ethernet payload [8] for PPPoE [3] is indicated by an Ethertype of 0x8864. References: I think that [9] needs to be a normative reference because the reader cannot understand the QFI field without it. Minor Concerns: Introduction: You spell out the meaning of 5G, but not BBF. Please spell out BBF. I note that 5G is on the RFC Editor "well known" list (https://www.rfc-editor.org/materials/abbrev.expansion.txt), but BBF is not, so it would be fine to not spell out 5G. Likewise, please spell out p2p, PPPoE, IPoE, DSLAMs, and OLTs the first time the term is used. Please explain the UE in the Introduction so that it is understood by the time it is used later. Please use the exact wording from RFC 8174 in the boilerplate: The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here. I assume that it is okay to use "[1] [2]" instead of "[RFC2119] [RFC8174]", but this is not the tradition. Section 2: Please add a reference for the IANA registry. I think you are pointing to here: https://www.iana.org/assignments/ppp-numbers/ppp-numbers.xhtml#ppp-numbers-2 Section 5: Please add pointers to the registry that is to be updated. I think you are pointing here: https://www.iana.org/assignments/ieee-802-numbers/ieee-802-numbers.xhtml#ieee-802-numbers-1 Nits: Abstract: I suggest that the Abstract say what is provided instead of the needs of 5G. It is also shorter. I suggest: As part of providing wireline access to the 5G Core (5GC), deployed wireline networks carry user data between 5G residential gateways and the 5G Access Gateway Function (AGF). The encapsulation method specified in this document supports the multiplexing of traffic for multiple PDU sessions within a VLAN delineated access circuit, permits legacy equipment in the data path to snoop certain packet fields, carries 5G QoS information associated with the packet data, and provides efficient encoding.
