INT AREA WIKI Page for IETF 100
The 6TiSCH working group has a stable set of "6TiSCH Minimal" specifications:
This forms a complete protocol stack, which can be implemented and benchmarked. Ongoing work in the WG focuses on augmenting this "Minimal" solution with:
7 drafts were presented t IETF 100, both related to the 6TiSCH Minimal specs and its extensions
The LPWAN Working Group met on Monday 13th for 2.5 hours and followed its agenda as scheduled with no particular issue.
A discussion of the LPWAN WG rechartering concluded that the group should focus on SCHC-over-FOO, and BAR-over-SCHC. FOO could include the four baseline technologies, or additional that may manifest themselves. BAR may include applications sitting on top of CoAP, such as LWM2M, CoMI or other. We consider setting up a repository for CoAP pcap traces, which will be used for profiling the applications. Additional items for the rechartering include the Data Model of the SCHC compression contexts and the minimal context provisioning protocol, as well as work on ICMPv6.
During the discussion on ICMPv6, it was observed that the work is two-fold. On the one hand, we need to describe how we treat ICMPv6 messages, such as whether we send the ECHO-request all the way to the device or proxy at the gateway, and whether we need new ICMPv6 codes in the ECHO-request to indicate the expected behavior. On the other hand, we need to specify new ICMP message codes to cover new situations that are related to the function placement in LPWAN networks, e.g. Error:Non-compressible packet. Many questions arise for ICMPv6 error messages, depending if the erroneous message is compressed or not, and which entity should receive the error message. Finally, standard traceroute uses random UDP ports for route mapping, which would result in un-compressible messages (messages that match no context or that match generic contexts).
Statuses of the drafts.
Non-WG documents for SCHC-over-FOO were presented for FOO in (LoRaWAN, SIGFOX).
A presentation of the ETSI ERM TG28 was done by the Chairs on behalf of TG chairs with the intention to dig into ETSI LTN in the next meeting.
Overview of IEEE meeting in Orlando was given by Bob Heile. Of interest is a new PAR on work on new PHY for LPWAN. Also, a study group on next-generation security was formed, as well as extensions to Field Area Networks.
During the Hackathon, several of the participants have improved the open-source SCHC implementation.
The Dynamic Host Configuration Working Group met on Thursday, November 16, 2017, 18:10-19:10 (a 1 hour session).
The chairs provided a Working Group status update and agenda bashing.
Tomek Mrugalski then presented a draft for a recharter and reviewed the current remaining work items and potential future items. There was some discussion on the charter and the chairs will update draft and distribute to the mailing list for further discussion.
Next, Ian Farrer presented an update on the DHCPv6 Yang model and next steps. He was also seeking additional participation, and several people volunteered to help out in reviewing the document and becoming potential co-authors.
Then Srivivasa Rao Nallurim presented two IoT DHCP option drafts, one a working group work item (draft-ietf-dhc-dhcpv6-lwm2m-bootstrap-options) and another he is interesting in having the working group take on (draft-nalluri-dhc-dhcpv6-mqtt-config-options).
