All, We had an ad-hoc meeting to discuss how to implement the action plan we identify at the last 6TiSCH Webex. While this ad-hoc meeting is not a 6TiSCH interim meeting, we believe it's important to post the minutes to the 6TiSCH ML.
You can find a formatted version of the minutes below at https://bitbucket.org/6tisch/meetings/wiki/151005_webex_otf. Thomas ---- Minutes, 05 October 2015, ad-hoc meeting OTFPresent - Thomas Watteyne - Xavi Vilajosana - Diego Dujovne action items - Thomas to coordinate with WG (deadline: 6 Oct) - Xavi to coordinate with Qin and provides first draft (by Thursday) - Diego to coordinate with OTF authors about reorg minutes - we need draft by 19 Oct - vision - We have 6top Sublayer draft which is generic and defines the tools we have to operate - We have OTF OF (From now on OTF0) which defines the specific setup to make things work using the sublayer tools. - tentative organization draft - Overview . - The 6top Sublayer . role: . [remove?] The current document does not define how flows with multiple priorities are supported. Future extensions to this document might add support for multiple priorities. . maintaining (basic) cell usage statistics . monitoring and moving (soft) cells . there is Objective Function (OF) that takes care of: . maintains some statictics as needed . maintaining the bandwidth, even when the PDR of the link to a neighbor changes. This might include detecting cells which suffer from collision, and relocating them to a dfferent slotoffset/channeloffset location in the schedule. . increasing/decreasing the bandwidth according to the application needs. . protocol to add/remove cells to a neighbor. The OF uses this mechanism. . a mechanisms by which a neighbor node discovers the OF currently in use by the 6top sublayer (OCP ID or something like that -- see RPL DIO OCP RFC6550). - Hard/Soft Cells . IEEE802.15.4e defines some flags . 6top adds additional qualifiers of a cell (NOT strictly speaking flags) . soft cells: 6top Monitoring Process active on the cell, the 6top OF is allowed to relocate it . hard cells: 6top Monitoring Process NOT active, r/o mode. Exact useage not defined, left open for future use. hard cells can only be read - 6top-to-6top Communication Protocol . based on IEs . TODO: coordinate with IETF to allocate IE numbering space . discovery - Example Scenarios - IANA
