Subject: RE: [ws-rx] Issue i096

Hi Paul,

The columns that were removed were on the RMD side. In the old table the author had assumed that if a RMD receives a message with a message number greater than the limit, that it entered a new 'rollover' state. I don't believe that state added any value, and don't think that the main spec mentions, implies or defines it. Having reached that conclusion I nuked the entire column ;)  The state transition that now occurs is that a fault is returned to the sender, but that the RMD is still in the 'Connected' state, so the RMS may continue to retransmit earlier messages.

The majority of the RMS changes are to ensure that each cell contains both an action and a next state, as the gaps were potentially misleading.

The RMD table changes as mentioned above, and I also clarified the rows corresponding to message arrival (with message number in range vs message number out of range).
I removed the RMD row corresponding to "Unrecoverable error on creation" as I don't think a sequence would be created at all in that case.

I removed the RMD retransmitted message row as the RMD won't always know if a message is retransmitted (the first transmission might have been completely lost). The main message received row should be robust enough to deal with this, and further detail sails close to RMD/AD communication issues that are out of scope.

I removed the RMD "message rollover fault" row, as an RMS is never going to send that fault to an RMD.

I removed the RMD "terminate sequence" row as it was a duplicate (see 3 rows above).

I hope that helps! Thanks for asking - I'm sure that you were not the only person who wanted a guide to the changes.

Could you give us some explanation of the changes?  In particular why are you proposing to remove two complete columns?

[ws-rx] Issue i096


Hi all,

Here's an updated PDF for the state tables. There are quite a few updates, all highlited in blue. If this proposal is accepted by the TC, I think this leaves the tables in a reasonable state (no pun intended), so if anyone has any further ideas for changes they are probably best handled under new, specific issues.

I also have the openoffice doc that produced the PDF - it may be useful for the editors if the TC accepts the proposal.
