Dave Chappell on "MOM, WS-Rel*, and Wire Protocol Interoperability"

["Chiusano Joseph" <chiusano_joseph@bah.com>]

Here's an excerpt from Dave Chappell's blog [1] on MOM and WS-Rel* that
some might find interesting. 

Here are excerpts (please note that any first-person references such as
"I" are from Dave, not me):

- It is conceivable, and also probable that a MOM implementation could
be based entirely on one of these WS-Rel* specifications [JMC: he refers
to WS-Reliability and WS-ReliableMessaging as WS-Rel*].

- However, that would still require a piece of MOM infrastructure be on
both sides of the wire to handle behavior such as acknowledgement of
receipt, message persistence, and recovery from failure. 

- From that perspective, what you gain by having an open protocol is the
ability to have the MOM piece of software on either side of the
conversation provided by a different vendor. 

- However this is at the expense of having less room to innovate on
efficiencies of acks and nacks at the message transport layer. 

- I am not trying to say anything negative about the need for WS-Rel*. I
am a big proponent of both of the WS-Rel* specs, and have contributed to
both. I am just trying to put it into the proper perspective.

Kind Regards,
Joe Chiusano
