"So, say you have 2 pipes and 1 is at 75% capacity and one at 25%. To balance (assuming simple round robin balancing) you kick 50% of the users on pipe 1."

66%.

Ooops yes

It was late. Hopefully the example works though

I always find gadamer the worse gateway for me. The rest all seem pretty much the same.

Why is this done so often?

To help balance the load!

Seriously, think of it as two parallel roads that both run to the same destination. One road gets busier and busier whist the other stays relatively empty. On the empty road you can do 100Mph, but on the busy road you can only do 5Mph - Big difference & I'd know which one I'd prefer to be on.

Now, if you were to balance this busy road then half the traffic is taken off the busy road and transferred onto the not so busy one, now both roads have an equal amount of traffic on and can both happily run at 100Mph.

Convert those cars to IP Packets & the roads into the various backbones of the internet and you'll see why load balancing is important.

Good network admins will always make sure that the loads on their servers is as equal as possible to keep the traffic flowing as smoothly as possible.

I'm not sure enforcing mass-disconnections is a great way of dealing with the problem. And I cannot believe this is the only way to achieve what needs to be done. It seems very sloppy especially when the solution impacts end-users equipment requiring unplugging of devices for at least 20 mins to resync properly.

I'm not impressed at all.

Have you ever had to do this?

Several of the forced disconnects have shown up in my router logs and I've not had a stale session yet.
