NAME

     fair -- simple TCP load balancing service

DESCRIPTION

     fair is a load balancer for TCP connections.  It can be used to
     distribute incoming connections for SMTP, HTTP or any other TCP service
     to multiple hosts, distributing the load as evenly as possible.

     fair consists of two daemons.  The carrousel is the front-end; it keeps
     track of back-end hosts and their status, and forwards incoming
     connections to the back-ends in such a way that the load is distributed
     fairly.  The transponder runs on the back-end hosts, it registers with
     the carrousel and sends it status information.  The TCP connections
     forwarded by the carrousel are not sent to the transponder daemons but
     are sent directly to the desired service running on the back-end host.
     Both daemons share a single configuration file.

EXAMPLES

     The following example shows how to set up fair to service HTTP
     connections and to distribute them over back-ends in the 192.168.1.0/24
     subnet.

     The configuration file /etc/fair.conf contains the following:

           WorkerService = http
           BalancerService = http
           AllowUDP = ^192.168.1.[0-9]+$

     On www.example.com, the front-end server receiving the incoming HTTP
     connections, just run:

           carrousel

     On each of the back-ends run:

           transponder www.example.com
