Abstract
Interactive (or Synchronous) groupware is increasingly being deployed
in widely distributed environments. Users of such applications are
accustomed
to direct manipulation interfaces that require fast response time.
The state that enables interaction among
distributed users can be replicated to provide acceptable response time in
the presence of high communication latencies.
We describe and evaluate design choices for protocols that
maintain consistency of such state.
In particular, we develop workloads which model user actions,
identify the metrics important from a user's viewpoint, and do detailed
simulations of a number of protocols to evaluate how effective they
are in meeting user requirements.
