  1. 1. 6TSCHORLANDO 86th IETF IETF 86 – ROLL WG – March 2013
  2. 2. BStatus: D A• MAC-only amendment to IEEE802.15.4-2011• Published April 2012• Ideas similar to ISA100.11a and WirelessHART C• Enables deterministic communication 10s to 1000sTSCH: C->A• Time Synchronization channelOffset Typically 16 –low-power consumption D->C• Channel Hopping –reliability D->BSchedule: B->A• clear trade-off between bandwidth,redundancy, latency and power consumption. slotOffset• How to build the schedule is out of scope.
  3. 3. • IPv6 access and routing over deterministic (Time Synchronized Channel Hopping) MAC• Mix of centralized and distributed routing• Put together architecture binding existing standards (RPL, 6LoWPAN, PANA, COMAN, ForCES/OpenFlow, NSIS/RSVP, diffserv) over 802.15.4e TSCH• Provide missing components and steer work

  6. 6. • Define scope and problem – Backbone + PCE + TSCH/RPL/6LoWPAN WSN – draft-phinney-roll-rpl-industrial-applicability• Define goals and delivables – Info: LLN context, Architecture, Terminology – New: 6TUS, Management protocols, track reservation – Adapt: 6TSCH RPL OF, fragment forwarding – Extern: Backbone Router, PCE, COMAN• Define dependencies and liaisons – IEEE 802.1TSN, ISA100.20, IoT6
  7. 7. • draft-phinney-roll-rpl-industrial-applicability• draft-palattella-6tsch-terminology• draft-watteyne-6tsch-tsch-lln-context• draft-wang-6tsch-6tus• draft-thubert-6tsch-architecture• List todos
