  1. 6TSCH Webex 05/17/2013

  2. Add note on visibility • It is our collective responsibility to make 6TSCH visible and attract participant • Paper @ Industrial Track in esIoT (July) • IERC Cluster Book 2013 • ?

  3. Agenda • BoF in Berlin: 40 minutes • Bootstrapping 5 minutes • 6TUS split: 15 minutes.

  4. BoF Request

  5. BoF request form 1) BOF's full name and acronym in brackets: Deterministic IPv6 over IEEE802.15.4eTimeslotted Channel Hopping (6TSCH) 2) AREA under which Working Group or BOF appears INT

  6. BoF request form 3) Chair(s) Name(s) and e-mail address(es) Michael Richardson suggests it is good that the chairs and people explaining things are not the proponents 4) Agenda (too long?) • TSCH presentation 30mn • Work items and mapping with existing work and WGs1H • Charter discussion 1H

  7. BoF request form • 3) Full Description of BOF WG creation BoF on Deterministic IPv6 over the TSCH mode of IEEE 802.15.4e. The WG will propose an architecture that supports centralized and distributed routing and resource allocation over a TSCH based mesh. The group will resolve the impacts on existing protocols such as RPL and 6LoWPAN. It will define a component that provides the expected link functionality for IPv6 over the TSCH MAC and a G-MPLS switching sublayer, and standardize the protocols and/or protocol extensions to establish time slots between peers and reserve resources along a path. <add links to drafts>

  8. BoF request form 5) CONFLICTS to avoid ROLL 6MAN CoAPCOMANINTAREARTGAREA 6) Expected Attendance : 60 7) Number of sessions: 1 8) Length of session: 2 1/2 hours

  9. Marc’s recommendations

  10. Control your scope A scope that is too large will scare people off Suggestions: • Start complex items with requirement draft : • Centralized computation ? • 6TUS subset ? • ?

  11. Inspire confidence People must understand that the WG can achieve deliverables in due time. Suggestions: • Say that we: • emulate existing industrial solution for centralized and TSCH, and Zigbee IP for distributed • produce the missing links either in-house or by pushing work to other WGs (we do reqs) • e.g. TSCH draft, architecture, coexistence with ISA et HART, applicability (indus, automation, …) • Existing drafts

  12. Clearly present gap analysis and problems to be solved Suggestions • Our draft charter has a gap analysis. Keep revalidating as our understanding evolves. • Include req drafts as work items. Should start asap • Spend enough time on charter work as opposed to solution drafts • ?

  13. Clearly propose work items People must understand that the WG can achieve deliverables in due time. Suggestions • Our draft charter has work items. Keep revalidating as our understanding evolves. • Spend enough time on architecture presentation so work items are clearer • ?

  14. Explain why this is IETF work Why work does not belong to existing WG Suggestions ? • There is IPv6 over foo and routing area work. Refer to architecture draft • Reqs are centered on TSCH use cases but work will be pushed elsewhere

  15. Show activity Suggestions: • Weekly call • Drafts and Repo activities • ML stats (135 members!!!) and archive http://www.ietf.org/mail-archive/web/6tsch/current/maillist.html • ?

  16. Do not deep-dive in drafts gory details That would lose the audience. Suggestions: • Keep it to Architecture and TSCH drafts • Req drafts focus?

  17. External relations Official Liaison work is double edged sword. Mostly keep informal, talk about exchanges. Suggestions: • Participate to ISA100.20 • Participate to IoT 6 • Participate to Heathrow group • Others ?

  18. Network bootstrapping

  19. Network bootstrapping ---+---------------------- | External Network | +-----+ +-----+ | | Router | | PCE/ | | | | NME +-----+ +-----+ | | | Subnet backbone | +--------------------+------------------+ | | | +-----+(RPL root) +-----+(RPL root) +-----+ | | Backbone | | Backbone | | Backbone | | router | | router | | router +-----+ +-----+ +-----+ o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o • - Security/ Authentication • Procedure for regulating schedule requests from motes to PCE 2. TSCH network – PCE connection / interaction • EBs configuration: • - transmission period • - slotframeID • - cell (i.e., timeOffset and channelOffset) NOT completely defined in IEEE802.15.4e! Many OPTIONAL features 6TUS network formation commands 1.TSCH network formation

  20. splitting the 6tus draft

  21. Current TOC 2. 6tus Adaptation Layer Specification 2.1. Overview 2.2. Link Model 2.3. Data Convey Model 2.4. Commands 2.5. Message Formats 2.6. Time Sequence 2.7. Statistics 2.8. Monitoring 3. Using 6tus 3.1. RPL on 6tus 3.2. GMPLS on 6tus

  22. Commands • Time Source Neighbor Commands • Set a node’s time source neighbor(s) • Neighbor Commands • Manage the neighbor table • Queuing Commands • Create a queue • Read queue statistics • Security Commands • Manage the node’s keying material • Data Commands • Send and Receive data • Link Commands • Add/remove hard/soft links • Slotframe Commands • Add/remove slotframe • Monitoring Commands • Configure monitoring process • Statistics Commands • Configure statistics to collect • Retrieve statistics • Network Formation Commands • Configure Enhanced Beacons contents • Configure when to send EBs

  23. Packet Formats • 6tus uses TSCH Payload IEs • Defined by IEEE802154e: • TSCH Synchronization IE • TSCH Slotframe and Link IE • TSCH Timeslot Template IE • TSCH Channel Hopping IE • Defined by 6tus • 6tus Opcode IE • 6tus Bandwidth IE • 6tus Generic Schedule IE • 6tus assembles IEs to form 6tus messages

  24. What 6tus does • Manages hard cells • “pass-through” layer for PCE • Manages soft cells • Negotiation protocol • Monitoring function • Switching based on (implicit) labels

  25. Proposal • 6tus specification • current draft • minus the negotiation protocol • plus the commands to manage the label switching • 6tus for centralized scheduling • how to use 6tus in the presence of a PCE • relates protocol between the PCE and the nodes • 6tus for distributed scheduling • negotiation protocol • monitoring function • 6tus support for label switching • switching a packet along a track
