Server Load
Balancing (SLB)
Overview
The Server Load Balancing (SLB) feature of the Intel
®
NetStructure
™
480T routing switch divides many client requests among several servers.
This activity is transparent to the client using the resource. It is mainly
used for Web hosting where several redundant servers are used to increase
the performance and reliability of busy Web sites.
Using SLB, the switch can manage and balance traffic for client
equipment such as Web servers, cache servers, routers, firewalls, and
proxy servers. SLB offers a variety of useful features that meet the special
needs of e-commerce sites, Internet service providers, and managers of
large intranets.
SLB Components
There are three components that comprise an SLB system:
• Nodes
• Pools
• Virtual Servers
All three components are required for every SLB configuration.
