Hello Tengfei
But if the ack is sent and not received then the parent does not allocate the
cells and the child uses them...
And if a transaction hangs in the middle - say the child dies or is out of
reach - then we'd have a deadlock.
No, as Xavi said we must plan for parallel transaction and
Hi Pascal,
The parent should allocate cells only when it received the ACK of the
response. If no ACK received, no cell will be allocated. This can be
handled by state machine, though it doesn't support concurrency.

Hi Diego,
Do we really require 3 transactions for 6P operations as mentioned.
The second transaction from the parent contains all the required information
for the task.
In case the 2nd packet is lost, the parent will schedule a RX link which will
be unutilized for the time being
One issue with that, Tengfei, is if the 6p response is sent but not received.
The client will retry the request for the same need of bandwidth but will get a
new set of cells.
The parent that allocates cells must correlate them with a request ID (token,
sequence, whatever) in case that request i
I’d support that, Diego
If the visible operation of the device depends on it and that influences the
interoperation, it is good to document a base way of doing things.
Cheers,
Pascal

Hello Diego:
One suggestion would be that when a node attempts to join, the parent
immediately grants a set of cells for the join process from a limited pool (to
avoid DDOS). These cells are to be released at the end of the join and are
there to boost the bandwidth for that critical phase.

Hello Diego:
You need a IANA section where you detail which registries you create and which
you add to.
Then you need to enumerate the entries that you need, as you do below.
You may suggest values to help interop till you make RFC, but the IANA will
have the final word and implementations may
Hello Diego,
*For IANA_6TOP_CMD_ROLLBACK command: *
I think I understand what you are trying to solve. But using
IANA_6TOP_CMD_ROLLBACK
has another issue: how to decide when to send the command. I think this is
the same question for setting the value of 6P_TIMEOUT.
Also if a transaction timeout b
Hi Xavi,
Thanks for explanation! It makes sense for me.
Xavi, Diego, All,
Does the token indicates the ID of one transaction? How this 8-bits value
changes during a transaction/multiple transaction? It would be helpful if
there is some martial showing how the token works with 6p. Let me know if
10 matches
