What is Load Balancing

Avaya P330 Load Balancing Manager User Guide
Load balancing technology allows system administrators to replace single
firewalls and servers with multiple firewall and server farms, achieving
the following goals:
• Improving resilience by removing single points of failure.
• Improving performance by utilizing multiple units instead of a
single one.
This improves the scalability and maintainability of the firewalls and
servers in the network.
The load balancer also serves as a 'smart redirector', allowing traffic
redirection, commonly known as Application Redirection. This allows
for:
• Invisibly intercepting web traffic and forwarding it to deployed
web caches.
• Redirecting specific application traffic to content inspection
engines.
• Policy based routing, providing routing based on application or
data source.
There are several different load balancing applications:
• Firewall Load Balancing (refer to "Firewall Load Balancing
(FWLB)" on page 4).
• Server Load Balancing (refer to "Server Load Balancing (SLB)" on
page 8).
• Application Redirection (refer to "Application Redirection (AR)"
on page 10).
