Andrei, there's no way to tell another client something like "hey, you're talking too fast to me, please slow down a bit". You can control bandwidth for packets leaving your host but not arriving (just to avoid the term upstream as it depends from the point of view what upstream traffic really is). If your host is serving content to clients, you should be able to serve all clients in a reasonable fair way by using queuing. But you can't do that per client or per connection. For a http server (or mail or whatever public service) queuing is one of the very first things to setup when going into production as you probably don't want all http clients eat up all your bandwidth and the machine will be unable to serve anything else. You need to create one queue (for example) for your http server and assign all traffic to your http server into that queue. Having a queue with a guaranteed bandwidth for every connection (client) would require the creation of "dynamic queues" on the fly. I'm not aware of such possibility.
