Components of Load Balancer that are available to use
This topic highlights the components of Load Balancer that are available for use.
Load Balancer consists of the following three components that you can use separately or together to provide superior load-balancing results:
- You can use the Dispatcher component by itself to balance the load on servers within a local area network or wide area network using a number of weights and measurements that are dynamically set by Dispatcher. This component provides load-balancing at a level of specific services, such as HTTP, FTP, SSL, NNTP, IMAP, POP3, SMTP, SIP, and Telnet. It does not use a domain name server to map domain names to IP addresses.
- You can use the Site Selector component to balance the load on servers within a local or wide area network using a DNS round-robin approach or a more advanced user-specified approach. Site Selector works with a name server to map DNS names to IP addresses.
- You can use the Metric server component to provide server-specific load information to the Load Balancer in the form of system-specific metrics, reporting on the health of the servers.
Note: The Content Based Routing (CBR) component that was previously provided with the Load Balancer
is now provided with the Caching Proxy component.
For more information about CBR and server components, see the resources about the CBR and Dispatcher, Site Selector, and Metric Server components.
