I didn't understand the question, please clarify what exactly you are looking for. In short, LB algo can be set to the simple roundrobin, and you also provide a set of backends servers to be loadbalance'd in the configuration file. haproxy starts up, read the config file, and acts accordingly. All new connections are sent to the different backends in a roundrobin fashion, and assuming each connection does similar amount of work, the traffic get reasonably distributed among the servers.
