      Numerous changes: · d6dfc183
      Mike Hibler authored
       * cloudinfo.in: change to handle hybrid (split BW/delay handling)
         delay pipe setup, also a hack to allow you to run the .in file out
         of your source tree
      
       * init-elabnodes.pl: handle hybrid cloud/lan model, use xmlrpc to find
         type of plab nodes and setup delays accordingly
      
       * auto-*.sh: continued attempts to get a meaningful exit status out
         of them for the program agent--still doesn't work
      
       * run-monitor-libnetmon.sh: make sure initial conditions get properly

      Mostly cleanup. · cde74d7a
      Mike Hibler authored
      * generate the initial conditions for monitors to pass into the stubs
        (must use -i to start-experiment to do this)
      
      * make sure install-tarball does not return til tarballs are installed!
        (or til timeout)
      
      * move ip mapping and initial conditions files to /local/logs so they
        become part of the record
      
      * fix up exit status' returned by auto-* stubs so program-agent
        can detect real failures

      First crack at surviving down planetlab nodes. If the master barrier sync · 5f413b47
      Mike Hibler authored
      node sits in the stub or monitor barrier sync for more than the SYNCTIMO
      timeout value in common-env.sh, it will send a HUP to syncd which will
      knock all the other nodes out of their barrier sync.  If that happens,
      all nodes will print a warning message and continue.
      
      All nodes wait for both a stub sync and a monitor sync, so if one plab node
      is down, they will timeout on both barrier syncs.  Race conditions?  Sure.
      If for example everyone times out on the stub barrier due to a slow node,
      and then that node reaches the barrier, it will hang there while everyone
      else waits on the monitor barrier.  When the latter times out, it will
      kick the slow node out of the stub sync and it will then proceed to hang
      in the monitor sync until the experiment is stopped.  Got that?
      
      As an aside, it would be nice if the initializer of a barrier could specify
      a timeout value, and return a special error code to everyone if it timed out,
      but that would require an incompatible change to the sync protocol.

      Fixed initialization bug in the bandwidth-measurement argument code. Fixed a bug where throughputTick was getting called too often. Added more data for DELAY_DETAIL logging. Removed Nagle's algorithm from the control traffic on the stub side. Added a new bandwidth option. Now there are three. Changed the naming scheme to be more specific (it was too generic before).

      Fixed a transient error discovered by Junxing. Rather, I've fixed a bug that could account for it and the error hasn't resurfaced after many runs. The transient symptom was when pcap only captured the first three packets and failed from then on.
      
      All measurement times are now based on packet timestamps rather than gettimeofday(), throughput measurement is much more consistent now, though a more thorough evaluation is still required.
      
      Delay is averaged over a quantum. This is probably not the right thing to do, but it is better than the alternative (latest measurement). I am still discussion with Sneha about what to do here.

      More work on the framework for running the monitor and stub · c8bbc432
      Robert Ricci authored
      automatically.
      
      Now automatically determines the number of peers in the experiment.
      
      run-monitor-libnetmon.sh automatically generates the IP mapping file
      now.
      
      Auto-create /local/logs if it doesn't exist (it doesn't on our
      devbox image)
      
      Add two new 'auto' scripts - these are intended to be run as part
      of the automatic experiments. They properly wait for the stubs
      to start before starting the monitors, etc. They log the outputs
      of the stub and monitor to /local/logs, where loghole can pick
      them up. They also kill their children if they are killed (to be
      used with the program agent)
      
      The auto-* scripts need a little more work in term of properly waiting
      for their children to exit.

      Added standalone support for multiple streams. Added a logging infrastructure. Added a trivial application for testing purposes (dumb-client and dumb-server). Added the capability for running the standalone stub with a tcpdump replay. Added support for changing buffer sizes. Added shell files for experiment management, reset.sh which is to reset the dummynet settings between runs and run-iperf.sh which encapsulates a set of options to iperf.

      Fixed several minor bugs in Rob's scripts. Added the capability for multiple streams along the same path to the monitor/stub loop. Replaced the linear searches with logarithmic searches. Cleaned up various associated parts of the code.
      
      TODO: Finish connection recycling capability
      TODO: Remove commented out older code after more debugging
