(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. o 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] o 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) o 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. o for the ICMP,(ping) if they are link local then the RPL artifacts are not needed and hence 6LoRH do not apply. o this points are useful for those implementations not implementing the whole set of protocols. o 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. o 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] o hackathon: OpenWSN, ...? o 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
