All,

The following are the suggestions and recommendations we mentioned during
the 6tisch meeting yesterday. Those points will be addressed and pushed to
the new version draft-ietf-6tisch-msf-02


   - The  NumCellsUsed is no incremented during backoff wait delay for TSCH
   retransmission algorithm. (suggestion: only apply adaptive traffic
   algorithm on non-shared cell)
   - Some usage about Frame Pending bit is under specified, the usage of
   pending bit in MSF will be updated once it's specified.
   - Only reserve autonomous cell on demand, for each node
      - Reserve one TxRx shared  autonomous cell to parent/JP (unicast
      cell)
      - Reserve one TxRx non shared autonomous cell (anycast)
      - Reserve at least one managed Tx cell  (reserved by Sixtop) aside
   with autonomous cell, and upstream application traffic only goes on managed
   Tx cells
   - EB can be sent when the node has a parent, DIO should be sent after
   when one managed Tx cell is installed to the parent

Regards,
Tengfei
