Hello Randy :) Section 5 is probably the one we care about most; the text derives from the 6TiSCH 4 detnet draft...
Regards; Pascal Le 17 avr. 2017 ? 20:53, Randy Turner <[email protected]<mailto:[email protected]>> a ?crit : Hi All, Regarding the recent call minutes and my action item, I did a quick glance at the use-cases defined in the DETNET use-cases document - I looked across all the use-cases, but particularly the electrical/smart-grid use-cases. The use-cases appear to be valid, however, It looks to me (you guys can correct me if you feel differently) that the problem statements and the latencies mentioned, are not approachable by wireless/RF networks. I'm not saying that deterministic methods (PCE scheduling, track switching, anything "MPLS-like or switching" on a mesh) wouldn't help, I just couldn't find any use-cases that could be addressed using the types of 6tisch networks (large/several-hops, lossy, 50Kbps - 1 Mbps) that I routinely deal with. The DETNET use-case document (as Pascal may have suggested in the past) seems to be describing problems that could be approached with "wired" DETNET methods only. The smart grid use-cases specifically call for 50msec latency across a grid network - any RF segment along this end-to-end link wouldn't necessarily be able to "guarantee" this. At least from my experience. Basically, the current use-case document appears to be a "wired" network use-case document.
