Subject: Re: RM - Definition needed!

The definition also needs a statement about non-delivery. A guaranteed
delivery-failure notification shall be delivered (in some unspecified
manner) by the From MSH to the From application if the permitted number of
retries are exhausted without receiving an acknowledgment by the To MSH
that it has received and persisted the message for processing by the
application.  The guaranteed delivery-failure notification is an essential
part of reliable messaging because it removes any doubt about whether the
To party did or did not receive the message in the case where the From
application has not received a response from the To application.

Subject:  RM - Definition needed!

It has been suggested that a useful step in the RM discussion is a simple
BUT succinct definition of what RM means.  I agree that this would be
to "scope" the discussion as many other issues tend to drift in and out of
this topic.

As a start to the discussion to define in 1 paragraph or less - I would
2 or at most 3 sentences, the start is:
"RM is a protocol between the sending and target MSHs to get an indication
that a message was delivered to the far end... pointedly, it has nothing to
do with the quality, existence or number of intermediate nodes in the

This is a slightly re-worded contribution for an external party but I think
encapsulates the sort of definition we need.
