Abstract
Much effort has been dedicated to the development of
applicationlayer and networklayer mechanisms for select
ing the ``best'' server among a set of replicated servers. In
this work, we highlight a different problem that arises in the
replicated server context; namely, when to to invoke and use
a server selection mechanism. We use the term ``binding''
to refer to the function that queries a server selection mech
anism and makes decisions about how to use the results.
We consider two extreme cases of binding frequency, Initial
Binding at the start of a connection, and Continuous Bind
ing for each packet. We propose and evaluate a Continuous
Binding scheme, and then compare these two extremes to
one another. Our results indicate that a single client can
