Load Balancing Services

The P333R-LB supports the following Load Balancing services:
• Firewall Load Balancing.
• Server Load Balancing.
• Application Redirection.

Firewall Load Balancing (FWLB)

The P333R-LB's FWLB intercepts all traffic between clients and servers and
dynamically distributes the load among the available firewalls, based on the FWLB
configuration. Using FWLB, all of your firewalls are utilized concurrently,
providing overall improved firewall performance, scalability, and availability. For
more information see Chapter 7, Firewall Load Balancing.

Server Load Balancing (SLB)

The P333R-LB's SLB intercepts all traffic between clients and servers, dynamically
distributing the load among the available servers, based on SLB configuration. For
more information, see Chapter 8, Server Load Balancing.
