Dispatcher component

This topic highlights the Dispatcher component of Load Balancer.

The Dispatcher component balances traffic among your servers through a unique combination of load balancing and management software. Dispatcher can also detect a failed server and forward traffic around it. Dispatcher supports HTTP, FTP, SSL, SMTP, NNTP, IMAP, POP3, Telnet, SIP, and any other TCP or stateless UDP based application.

All client requests sent to the Dispatcher machine are directed to the "best" server according to weights that are set dynamically. You can use the default values for those weights or change the values during the configuration process.

Dispatcher offers two forwarding methods (specified on the port):

The Dispatcher component is the key to stable, efficient management of a large, scalable network of servers. With Dispatcher, you can link many individual servers into what seems to be a single, virtual server. Your site is presented as a single IP address to the world. Dispatcher functions independently of a domain name server; all requests are sent to the IP address of the Dispatcher machine.

Dispatcher brings distinct advantages in balancing traffic load to clustered servers, resulting in stable and efficient management of your site.
