INT AREA WIKI Page for IETF 99
There were 3 6TiSCH-related events at IETF99.
The 1st F-Interop 6TiSCH Interoperability Event (http://www.etsi.org/news-events/events/1197-6tisch-interop-prague-2017) took place on 14-15 July, just preceding the IETF. 16 entities participated, with a test decription focusing on 6TiSCH (RFC8180, draft-ietf-6tisch-6top-protocol, draft-ietf-6tisch-minimal-security) and related security (OSCOAP, EDHOC). 6TiSCH is now supported by all mahor 156 tests were run, 86% of them passing.
6TiSCH-related projects took part at the hackathon, on 16 July. 6TiSCH is now supported on all major open-source implementations: OpenWSN (http://www.openwsn.org/), Contiki (http://www.contiki-os.org/), RIOT (http://riot-os.org/). Further work included full support of the entire 6TiSCH security bootstrap in OpenWSN.
The 2Hours WG meeting was organized around 3 sections.
6P protocol virtually finished, SF0 goes experimental: immediate future work on SF.
draft-ietf-6tisch-6p-protocol-07\ is almost final, with some final suggestions coming out of the plugtests. There was some discussion about the "generation counter" field, which was resolved during a side-meeting later at IETF99.
draft-ietf-6tisch-6top-sf0-05: the WG discussed whether to change the status of this draft to experimental.
minimal-security stable and implemented, several complementary work, concern about EDHOC not having a home at IETF.
draft-ietf-6tisch-minimal-security-03: the complete solution was shown to work at the plugtests. There were discussion about the fact that, after 5 hops, the solution requires 6LoWPAN fragmentation. The chairs expressed concern about the fact that EDHOC still has no home at the IETF.
draft-ietf-6tisch-dtsecurity-secure-join: optimized procedure of ANIMA BRSKI for 6TiSCH
draft-richardson-6tisch-join-enhanced-beacon: an additional header in the beacons to configure nodes to serve as join proxies or not. 10 people thought it's a good idea to adopt the draft, none against.
draft-richardson-6tisch-minimal-rekey: COMI-based rekeying
lots of new work around 6TiSCH
draft-duquennoy-6tisch-asf-00: interesting new SF concepts, chairs encourage authors to continue working on it
draft-munoz-6tisch-examples-02: important support document, discussion about where/how to publish it
draft-papadopoulos-6tisch-pre-reqs-00: new concept, no time to discuss
draft-lijo-6lo-expiration-time-04: not presented (out of time)
6lowpan-ND related extensions:
https://datatracker.ietf.org/doc/html/draft-ietf-6lo-rfc6775-update ( WGLC deadline terminated, comments received and discussed, new revision will be published for the next step)
https://tools.ietf.org/html/draft-ietf-6lo-ap-nd ( Under security expert review)
Applicability & usecases:
https://datatracker.ietf.org/doc/html/draft-ietf-6lo-use-cases (improved to focus on 6lo applicability and guideline for 6lowpan stack adaptation on a L2-constrained networks)
Discussion on Fragment Forwarding:
draft-thubert-6lo-forwarding-fragments was presented 2nd time to make the WG aware of issues of 6lo packet fragmentation over route-over links such as in RPL topologies. There were long discussions on forwarding requirements and possible solutions and the decision was to form a design team to further investigate 6lo fragmentation requirements on route-over topologies and come up with one or more possible solutions. The chairs are collecting names for people interested in the fragmentation design team.
The DHC Working Group met on Wednesday July 19th at 13:30 for 90 minutes.
The WG chairs (Tomek Mrugalski and Bernie Volz) discussed the agenda for the session and provided a brief WG status summary and update on the status of draft-ietf-dhc-rfc3315bis.
Next, John Brzozowski presented on the DHCPv6 Deployment at Comcast for millions of devices and where 99% of all cable modems are IPv6-only and 16 million set-top boxes use DHCPv6 (they request an IA_NA and IA_PD) using the Dibbler client.
Tomek then presented on the current status of the draft-ietf-dhc-sedhcpv6 work and recent issues. Following this there was a lively discussion on what to do about this work. The consensus of the room seemed to be to put the work on hold, update the draft-ietf-dhc-rfc3315bis by removing the reference to the sedhcpv6 work, and documenting the state of and need for security/privacy for DHCPv6.
Next was a (remote) presentation from Srinivasa Rao Nallurim on DHCP/DHCPv6 options for LWM2M bootstrapping (draft-nalluri-dhc-dhcpv6-lwm2m-bootstrap-options). Some feedback was given on this draft and the WG will do a call for adoption when requested by the authors as there is no other home for this work.
The last presentation was from Danny Moses on Ondemand Extensions to DHCPv6 for IP Session Continuity Requests (draft-moses-dmm-dhcp-ondemand-mobility). Some feedback was given on this draft and it was recommended that the authors and LWM WG keep the DHC WG updated on the draft as it progresses or if there are major changes.
The LPWAN Working Group met on Friday 21st AM1 for 2 hours and followed its agenda as scheduled with no particular issue.
