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
