10.4.1. Overview

The Server Load Balancing (SLB) feature in NetDefendOS is a powerful tool that can improve the
following aspects of network applications:
• Performance
• Scalability
• Reliability
• Ease of administration
The primary benefit of SLB is to allow the network service load to be shared across multiple
servers. This can improve not just the performance of applications but also scalability by allowing a
cluster of multiple servers (sometimes referred to as a server farm) to handle many more requests
than a single server. The illustration below shows a typical SLB scenario, with Internet access to
internal server applications being managed by a D-Link Firewall.

Note: SLB is not available on all D-Link models
The SLB feature is only available on the D-Link DFL-800, DFL-860, DFL-1600 and
DFL-2500 product models.
