Server Load Balancing (SLB)

24.1

Overview

Server Load Balancing (SLB) is a mechanism dealing with distributing the
traffic load across multiple servers to scale beyond the capacity of one single
server, and to tolerate a server failure. This technology is integrated in
D-Link firewalls to enable high performance and throughput of the network.
24.1.1

The SLB Module

In the SLB module, a network appliance acts as a Server load balancer,
connecting the network where the request traffic comes from with a cluster
of servers called Server farm.
SLB logical view
Figure 24.1 illustrates a logical view of a SLB module. In this module, 3
servers construct a server farm, and a D-Link firewall acts as a sever load
balancer.
Server farm
A collection of computer servers usually maintained by an enterprise to
accomplish the service needs far beyond the capability of a single machine.
