Hi,
From: 6lo <6lo-boun...@ietf.org> On Behalf Of Pascal Thubert (pthubert) Sent: Tuesday, 16 August 2022 13:42 To: Kiran Makhijani <kiran.i...@gmail.com>; carle...@entel.upc.edu; 6lo@ietf.org Subject: Re: [6lo] Call for WG adoption of draft-li-6lo-native-short-address-03 Hello Kiran Note that the core of the work is an autoconfiguration model along a fixed tree structure, and the desired “side effects” are implicit routing and short addresses. For short addresses, we already have SCHC and 6LoWPAN so that would not be a sufficient argument. Concerning the short addresses, it is true that SCHC and 6LowPAN go a long way. However, as we state in the last version of the doc (but I will make it sure to clarify more) the main advantage is stateless forwarding. The latter goes a long way in reducing control packets in the network and memory usage on the nodes. Now, I do not see how your point on IIoT matches this specification. Since a main objection (though not the only one) is the lack of applicability, this may help. Could you please elaborate? In particular, which industrial protocol would benefit from this automatic assignment of IP addresses (vs. Say, mapping the protocol address into an IID or something)? We did not explore IIoT scenarios so I have no answer to where are the benefits. I would argue, however, that the fact the solutions exists already does not mean that other newer solutions would not bring any advantage. @Kiran: looking forward to discuss more on this topic with you. Ciao L. Many thanks in advance; Pascal From: 6lo <6lo-boun...@ietf.org<mailto:6lo-boun...@ietf.org>> On Behalf Of Kiran Makhijani Sent: mardi 16 août 2022 2:08 To: carle...@entel.upc.edu<mailto:carle...@entel.upc.edu>; 6lo@ietf.org<mailto:6lo@ietf.org> Subject: Re: [6lo] Call for WG adoption of draft-li-6lo-native-short-address-03 Hello, I have quickly skimmed through the document and would like to see this work progress. I see that the focus is mainly on wireless constrained devices, however, in industrial networks with field devices it is useful to have short and variable addressing schemes on a factory floor. Variable addressing approach is more interesting here because, on one side the controllers may use IPv6 addresses and field-devices on the other end can very well be shorter addresses. I support this document and wouldn't mind contributing to the alignment with above mentioned scenario.
