SOLUTION FOR ASSIGNMENT #4                                       Spring 1999
--------------------------

The results are less than intuitive (run time = 100,000 sec):

  Random balancing (LoadSplit) = 0.550 sec (for mean response time)

  Round robin (TurnTaker) = 0.315 sec

  Shortest queue (ShorQ) = 0.320 sec

Thus, the best buy appears to be the TurnTaker product which is probably
lower in cost than ShortQ since it does not require knowledge of load
information in the two servers.  In any case, all three products are
a tremendous improvement over the unstable utilization > 1.0 case.

For the extra credit, there are a number of commercial products that
load balancing of clustered Web servers.  Cisco has the LocalDirector
and Alteon the ACEdirector.  Hydraweb and F5 are two small start-ups
in this business.
