Information on Software load balancing methods required!-

As I am aware, there are both Hardware and Software Load balancing
methods/servers available in the Market.
I favour for the Software load balancing method(eventhough it needs to
be run on a separate Hardware), as it will be cheaper compared to the
dedicated Hardware load balancer. I would like to get your suggestions
also on the same. Could you also provide information on some of the
popularly known/used software load balancing methods in the Market(not
very simple ones like DNS method where server unavailability is not
detected)?

What type of loadbalancing are you talking about ?
Network layer, physical layer, application layer - what ?

For each application of loadbalancing, there will be numerous solutions.

Just FYI, apart from the very simplest types (on the network layer) all
loadbalancing is done in software; something needs to make
semi-intelligent decisions about what, when and why to loadbalance.
That something will be a program.
