Load Balancing is used in the context of using multiple processors
to handle the load that a single logical entity is asked to
service. In a network with a very large number of subscribers,
a given function (like an inbound proxy server for example) may
not be able to be handled by a single CPU. In that case, you
often use a cluster of cpus, each running a copy of the same
code. Load Balancing refers to the mechanism used to allocate
work to each of the processors in the cluster such that the load
is balanced well enough that any one processor can handle the
fraction of the load assigned to it. There are many schemes in
use to accomplish this. In one, all initial INVITES are directed
to a single CPU whose only task is to allocate the work, for example,
using a round robin algorithm, to the worker processors. Subsequent
messages can be directed to the assigned processor.
