Re: [ws-rx] NEW ISSUE: semantics of "at most once" delivery assurance

[Dan Leshchiner <dleshc@tibco.com>]

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?

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.

However, the protocol as specified would never be able to complete a

if there are lost messages from the RMD perspective and the RMS is not
retransmitting them.


      

why so? as RMD, if i see a gap or AckRequested for a sequence number i 
have not received and i am operating in "at least once" mode with my AD, 
    

why cant i just send an Ack? if i did so, wouldn't that enable us to 
complete the sequence?

thanks,
