Application 4— Policy-Based
Load Balancing
Policy-based load balancing allows you to provide
tiered services. Preferred users receive better
service/access and you can charge those customers
according to the level of service they receive. This
process of maximizing the use of current resources
is transparent to the user.
Implementation: The first stage is to define groups
of users and servers (gold, silver, etc.). The servers
provide identical services. “Gold” users are directed
to the “Gold” servers, “Silver” users are directed
to the “Silver” servers, etc.
Advantages: Other load balancers on the market
redirect traffic based only on a division of users and
servers to “Gold” and “Silver” groups. However,
Avaya’s policy-based load balancing gives the best
use of current resources by continuously checking
the status of the “Gold” and “Silver” groups. If the
“Gold” group is more loaded than the “Silver”
group then the “Gold” user will receive service
from the “Silver” group. Thus “Gold” users will
always receive the best service.
Policy-Based Load Balancing and Service Providers
The same application can be implemented with
cache servers, so Service Providers can give the
best service to preferred customers. The customers
only notice improved service—without any
reconfiguration and complications.
