Subject: Re: [ws-rx] NEW ISSUE: semantics of "at most once" delivery assurance
if AS makes RMS aware that AtMostOnce is used by AD/RMD, then RMS can
assume that no retransmissions will be necessary and, consequently,
does not need to take up its resources to make retransmissions
available, right? Christopher B Ferris wrote: I think you meant AtMostOnce mode. I suppose you could do that, but from the perspective of the RMS, it is still retransmitting until it receives an ack.
