  2. Paul Chilton, NXP Semiconductors Los Angeles, CA January 20, 2014 TG9 KMP Document Statusand further work

  3. Paul Chilton, NXP Semiconductors Document Status • We are now following 802.15 rules • Now stored in private area of document server • Access for voting members of 802.15 using username and password • Anyone contributing or reviewing but not a member of 802.15 see me • Naming convention has changed • Document when released to review is a Draft ie d01 etc • Prior to this (where we are) the doc is a predraft • Doc now named accordingly – latest is • predraft5_P802-15-9_Draft_Standard.pdf

  4. Paul Chilton, NXP Semiconductors Changes since predraft4 • Acted on review comments received on predraft4 • Added Annex A – 802.1X text • Thanks to Brian et al for providing • Trawl through the document • Correct editorials, clean up language and diagrams • BUT now there are so many changes, change bars will be of little use, so • Predraft5 released with no change bars • It still needs people to review • I may have not understood something and altered the meaning by my edits

  5. Paul Chilton, NXP Semiconductors Todo List • Complete the primitives for using the KMP transport service • Define the operations and parameters • Text to describe them • Sequence Diagrams • Security PIB elements (eg macRekey etc) • Remaining text for Annexes • Check and correct formatting

  6. Paul Chilton, NXP Semiconductors Some thoughts • Separate KMP transport service from MAC • Don’t add commands into MAC, define separate KMP management layer • Eg KLME-Start.request • Even more radical • Separate KMP transport from the fragmentation and reassembly • Fragmentation service becomes general purpose for use by other services which need to transport frames larger than MAC • KMP uses fragmentation service • FLME-Data.request, FMLE-Data.indication etc • May make it easier to implement KMP operations by hiding the fragmentation mechanism

  7. Paul Chilton, NXP Semiconductors Some more thoughts • Should we test the design by trial implementations of some of the KMPs? • Checks that the services and parameters are adequate • Provide a reference implementation for the KMP • Do we need an explanation of the 802.15.4 and 15.7 security? • Implementors can see what security PIB information needs to be filled in by their KMP
