Re: evaluation of OMG DDS as a controls protocol for EPICS

   Thanks for sharing, Claude!

   I have been watching DDS "from the sidelines" for some time now.

   Ignoring the technical details, my chief reservation is that DDS 
does not
seem to be achieving widespread support, despite active marketing by RTI.
Disclaimer: I am actually a very satisfied user of other RTI S/W, but trying
to use a communication standard that is not widely adopted gives me visions
of trying to make hotel reservations in Esperanto. :-)

   On the plus side, DDS does provide "connection management" (built
on top of UDP/IP), and (more importantly, perhaps) includes some level
of support for user-defined Quality of Service (QoS) parameters when
establishing connections.

   Did you learn anything about DDS's QoS capabilities that could
(theoretically) be applied to CA?
