The common implementation is an external PLC interface plug, to which an Ethernet cable is plugged that runs to a free Ethernet port of the Home Router. But a built-in PLC interface is also well possible, same network diagram in either case :)
I have a bit of concern about the naming of the "PLC GW" - a gateway as terminology has a potentially wide scope and may be translating at all layers (e.g. between different link technologies, or different application layer command sets, IP to non-IP, or a combination of all these). If the link technology on top of the PLC GWs is PLC, and on the bottom of the PLC GWs it is also PLC, then it is more like a "PLC router" (6LR in 6LoWPAN terms). If the link technology on top of the PLC GWs is PLC, and on the bottom it is something different (e.g. wireless 6LoWPAN?) then it is more like a PLC/6LoWPAN Border Router (6LBR). It would be useful to clarify here; the role of PLC GW is now a bit confusing. For example in many houses you can plug the PLC Home Router in the living room, and another device in the attic, and both sides would connect over powerline without any gateway/IP-router device in between.

Actually it is a good idea. I should suggest it to my Internet provider :) Regards David -----Original Message----- From: Michael Richardson [mailto:mcr+i...@sandelman.ca] Sent: Monday, 14 November 2022 18:48 To: Esko Dijk <esko.d...@iotconsultancy.nl>; Zhe Lou <zhe....@huawei.com>; 6lo@ietf.org Subject: Re: [6lo] PASA smart home use case I assumed that the HomeRouter had a physical interface that was a PLC. Maybe it's physically a USB cable, but the PLC's layer-3 interface was inside the homerouter. -- Michael Richardson <mcr+i...@sandelman.ca> . o O ( IPv6 IøT consulting ) Sandelman Software Works Inc, Ottawa and Worldwide _______________________________________________ 6lo mailing list 6lo@ietf.org https://www.ietf.org/mailman/listinfo/6lo
