- last meeting before IETF meeting in Prague.
- thomas proposes a change to the agenda
- Lijo 's presentation will be first.
- Agenda and last call minutes are approved.
- Approval minutes from last meeting
- Addressing todo's from last time
- Announcements
- TEE webinar
- webinars at the IETF about TEEP. (Trusted Execution Environments). Links to the webinars in the slides.
- Maria-Rita's non WG forming BoF
- Info session about M2MSAT at ESA. Study the performance of M2M protocol
- to use them in satelite networks.
- targeting CoAP and MQTT.
- simulated environment.
- OpenSand is used.
- session after 6TiSCH meeting.
-
IETF99, getting ready
- activities around 6TiSCH
- plugtest friday afternoon and saturday.
- 6tisch meeting will not change.
- 11 days until draft cut-off.
- Agenda for the meeting will be published right after that.
-
-
draft-ietf-6tisch-terminology-09 [5min] [Maria Rita]
- published 19th June.
- main change related to security terminology. Update with the new security drafts.
- updated reference.
-
draft-ietf-6tisch-6top-protocol (Xavi, Qin) [10min]
- Xavi presents. 06 published, forgot to update the references so a 07 will be needed soon.
- 07 published next week
- Jonathan comments being addressed
- a MAY is changed to a "are"
- same type of error returning different values
-
Security DT Update [10min]
- draft-ietf-6tisch-minimal-security-03 [Malisa]
- added an optional ack from the JRC so the JRC can wait other messages
- how JRC learns the JP address
- communications happens at IP.
- JP forwards directly to JRC
- Join response contains the address.
- the dagroot is preconfigured with JRC address before the network can boostrap.
- Mandatory to implement AEAD Algorithm. Uses the COSE registry
- implementing it with PSK.
- Thomas: What is missing? is it ready, are there todos?
- Malisa: Details in the proxy mechanism. As of now, fine for 6TiSCH but not generic for CoAP use case, make the proxy option decryptable for others.
- Malisa: Biggest issue is status of EDHOC draft.
-
Plutests Update [15min]
-
admin [Thomas]
- start 2pm Friday 14 July
- room open all day
- saturday all day
- agree on a date with the participants to synchronize.
- Monday 3rd works for key players to sync?
- seems answer is yes
- MR to send a mail to the plugtest ML
- just supporting the page 1 switch in case there is no RPL
- Pascal= link local communication do not have RPL artifacts; for now they can live on page 0, that's true for ICMP e.g. ping and most RPL (but not non storing DAO)
-
update TD [Maria Rita + Thomas]
- Thomas shows the latest test description.
- The document specifies the default parameters
- 5 categories, synch, test about minimal (formats), security (join),
- sec join is just one part of the test, people can still participate to the plugTest without that implementation
- If you pass all these test you can make a demo of aproduct that works in the general case
- Supporting RFC8138 for those that do not have it can be easily done by just; supporting the dispacth value for page 1 as page 0 and page 1 is the same.
-
for the ICMP,(ping) if they are link local then the RPL artifacts are not needed and hence 6LoRH do not apply.
-
this points are useful for those implementations not implementing the whole set of protocols.
-
update golden image [Tengfei]
- updated 6P protocol to be compliant to v5.
- uses openwsn.
- there is a command to trigger a 6P command.
- the wiki page of the plugtest has a guide for the commands to be used.
-
update tools [Remy]
- soon the tools will be ready. Remy will do a run through on the tools at the beginning of the PT.
-
-
AOB [10min]
-
hackathon: OpenWSN, ...?
-
draft-lijo-6lo-expiration-time-03
- this item is discussed first:
- document draft-lijo-6lo-expiration-time
- packet expiration time in 6lowpan routing header
- motivation is to support delay sensitive M2M IoT Applications
- interest on including packet expiration time in IPv6 header
- Updates:
- including the Network ASN in the IP header
- ..
- Uses 6LoRH. Provides an elective header to transport the packet expiration time.
- Next step is to develop an SF that exploits that functionality.
- Thomas: should we account for the delay in the device before passing to the stack?
- Xavi: you are assuming 6TiSCH but the draft is sent to 6lo. Why not submit to 6TiSCH?
- Lijo: 6TiSCH is the use case
- Pascal: Agree with Xavi
- Thomas: Yes 6TiSCH is a good place
- activity around 3 drafts:
- 6775 update
- BBR
- address protection
- pay attention to WGLC, basis of our work, review and support
