Current Prototyping
   Running Timber – no problems
   Running LSA’s with Remote Desktop.
          Good news about LSA’s
                  Was able to run the applications with Mike Lamont in real time over WebEx’s application sharing.
                  Java Webstart works very well for deployment
                  Easy to keep current (basically automatic)
                  Looks like a very good solid SW architecture – no hacking
                  Consistency in GUI pays off in reducing learning curve
          Issues with LSA’s
                  No Safeguards*:
                            Some devices such as power supplies have permission management on user name basis, but the permissions are not managed in
                             the Java Applications.
                            CERN is not likely to add this in the near future for us. Options need to be researched. Some ideas are:
                                      We help develop the permission scheme and modify the applications
                                      We replicate the data base in real time, all our applications will operate on our local data base only.
                  Minimal documentation
                            As we learn we may be able to help write documentation
                  Speed is OK now, will decline with traffic. We need to have a fall back plan if it does.
          Issues with Remote Desktop:
                  locks up every once in while
                  screen size does not adjust well
                  font size is very small
                  mounting local drives is unsafe
                  painfully slow to copy on local drives

     * Safeguards: the LHC applications at LHC@FNAL should not be able to change the LHC settings in any way. They should only have the monitoring
           capabilities. The permissions should be based on a user name.
   Console Manager
          Able to run it, but don’t understand the details yet

Architecture Ideas
   Two PC’s per console
        Business applications
        LHC applications
   Pre-built SW images for both PC’s, easy to swap on failure
   Networking
        Latency 125 ms – affects GUI operations. Minimum response time is round trip 250 ms. Ok for now,
         but difficult to predict once traffic increases.
        Current link from FNAL to CERN is 622 Mb/s. Have alternatives if this becomes the bottle neck.
        Link from FNAL to office/LHC@FNAL is 100 Mb/s.
        Limitations and parameters:
                Speed of CERN’s Terminal Server
                Number of users
                Number of applications running
   Security (needs lots more work)
        Become cern.ch domain
                Security is managed by CERN
                Involves cooperation and some work by CERN
                Done by Minos (FNAL knows how to do this)
        Remote Desktop
