There are so many different ways to implement this, at different layers. I have seen layer-7 proxy based load balancers, but also layer-3 direct-routing ones, with other options in between. Some look like a client to the back end servers, but others need cooperation from those servers. The sum of load balancers and back end servers have to look like an end-node to the outside world, but inside anything (well, almost) is possible. So, can we compile a list of load balancing methods and can we specify what is needed for each method? Do we want to do this? Or can we say 'the server farm as a whole needs to behave like an end-node'? But I fully agree: we need to say *something* about load balancers! Sander
