However, what i have in mind is somehow similar to cpu-resources and process-priority. If i start at process with nice level 15, it will get all available cpu-resources without slowing down the other apps. As far as i understand, this is not the same as limiting the process to, say 80% of cpu power. Now, what i want is the same for p2p apps - give them as much bandwidth they can reasonably get but don't let them slow down firefox, ssh etc. Because i want this setup just for my homenetwork, it would perfectly suffice if packages get their priorities by examining port-numbers. And because i want to at least partially understand what i'm doing i would prefer a simple and clean setup. I know that in principle the neccessairy steps to do what i wannt can be found in the 'Packet Shaping HOWTO'. But i wanted to hear experiences and opinions of others first before starting messing around with my router. By the way, there are many different packet shedulers in the kernel - and the HOWTO only explains the HTP-scheduler. What about the other schedulers - can they be usefull for my purposes too - and if yes, how can they be configured and used ?
