Re: question on tpa documentation

Marty,

IMHO, There is need for alignment between the work being done in TRP for reliable
messaging and QoS specification
in TPA. Some examples of QoS that come to mind are:

-Send and forget/pray (best effort delivery)
-At most once delivery
-Once and only once delivery

As I recall TRP reliable messaging specifies At most once delivery with optional once and
only once delivery.

Some other aspects to QoS that I can think of are:

-latency constraints on message delivery
-Size contraints on message

As I recall there is something in current TPAML that specifies the latency constraints.

In any event I think Rik is suggesting that we need to plan for alignment on the QoS
specification in TP w.r.t
reliable messaging in TRP.
