Subject: RE: [ws-rx] New proposal for i019 and i1028

Hi Stefan,
Maybe I am looking at this in a simplistic way, but I can not follow the issue you have with the current proposal and how the alternate proposal addresses the issue.
It seems to me the fundemantal problem is for the RMS to determine the state of the RMD (thus resolving doubt) Thus, if the RMD were to send the final acknowledgement along with the ack ranges that indicate the messages that are received by the RMD, RMS has enough information to reconcile its own status with the RMD (basically it can diff the sequence numbers to obtain those messages which were in doubt but confirmed to be received by the RMD per the final ack). I am not clear as to why we need to do more here.
Perhaps you can clarify for me why your proposal is a better proposal and what the problem that Doug's proposal is not solving. It seems to me that in both cases the protocol is changed, but the proposal you are making is more complicated but functionally equivalent. I would like to understand the motivation for the complexity.

Subject: [ws-rx] New proposal for i019 and i1028



After much discussion Doug has managed to make me understand his reasons for proposing his Close/FinalAck mechanism for addressing i019 and i028. We now agree, an accurate acknowledgement state can be helpful in order to resolve doubt and in addition, for cases where a sequence must be ended, that acknowledgement state must be final. These are preconditions for recovery and the protocol can aid in establishing these preconditions.


However, we still have an issue with the current proposal [1]. We think it conflates the notions of resolving doubt and closing sequences. Attached is an alternate proposal that we believe addresses this issue, allows for the exact semantics [1] provides and has other advantages. Details are in the document.

I look forward to the group’s comments.
