draft-ietf-6tisch-6top-protocol-03

draft-ietf-6tisch-6top-sf0-02

draft-ietf-6tisch-6top-sf0 Created tickets on the issue tracker Solved as many tickets as possible Ticket 51: Editorial Changes Removed acronyms and used the following terms: Incoming traffic Effectively Used Cells Outgoing Cells Improved introduction explaining the purpose and the SF0 design Corrected the Allocation Policy figure 10 10 10 10

draft-ietf-6tisch-6top-sf0 Ticket 53: Timeout calculation There is still an open discussion on this matter, I would ask Nicola to add a more detailed explanation on the current formula. There is a contradiction on the 6P draft, first saying that the SF MAY define the timeout on section 4.1.1 and then that the SF MUST define the timeout on section 5.2 11 11 11 11

draft-ietf-6tisch-6top-sf0 Ticket 55: Comply with 6P requirements for SFs Added a compliance section taken from the requirement list on the 6P draft Only missing two MUST items: Timeout Statistics (PDR) definition Ticket 57: Improve figure on SF0 allocation policy Overlaps with one of the items from editorial changes. Done. 12 12 12 12

draft-ietf-6tisch-6top-sf0 Ticket 56: Performance evaluation There is still no performance evaluation available. I have a student working on it, but still no results. I ask volunteers to help on this issue. Ticket 58: Meaning of Metadata The metadata fields are explained on the corresponding section. We use a bit for the whitelist/blacklist identification and 7 bits for the slotframe number. 13 13 13 13

draft-ietf-6tisch-6top-sf0 Ticket 59: Cell relocation We need performance evaluation for the current algorithm to support the “PDR 20% less than the average of the rest of the allocated cells” value. Ticket 52: Whitelist/Blacklist Enhanced the explanation for this item on the text. 14 14 14 14

draft-ietf-6tisch-6top-sf0 Ticket 54: Bandwidth -> Cells There should be no more references to bandwidth on the draft. Changed the Bandwidth Estimation Algorithm to the Cell Estimation Algorithm. There is no more mapping to the number of cells according to PDR, now both algorithms run independently. 15 15 15 15

draft-vucinic-6tisch-minimal-security-00

see dedicated slides

draft-richardson-6tisch-dtsecurity-secure-join Michael Richardson Your Name HERE! 18

Status Goal: securing the join process News: Next: Aligning as much as possible with ANIMA and NETCONF WG, while adapting to limits of constrained devices and networks News: dtsecurity-secure-join-01 posted last week. Draft-richardson-6lo-ra-in-ie posted last week: discussion says do not make a general mechanism, but an RA specific mechanism, and that this work is within the 6tisch charter. To be revised ASAP. Also contribution: draft-vucinic-6tisch-minimal-security-00 Next: New meeting: Nov 8 meeting to include discussion of vucinic-6tisch-minimal-security 19
