Long time ago, when computers are not as fast as the ones we have now, we used to feel severe slowdown of computers when somebody starts a CPU-bound processing. A command, nice, was introduced to ease such a situation, by gracefully sharing the limited CPU resource with others. This simple mechanism, to lower process priority, made the system much more usable, and made everyone happier.

Now, we have observed amazingly rapid expansion in the network coverage and its bandwidth. Nevertheless, when someone starts an intensive application, such as file-sharing service, we would still suffer from performance deterioration of the network. Indeed, the network resource is still severely limited in most of the places, and thus, it is fairly important problem to utilize the available resource as best as we can. Netnice is a new primitive for an end-host network control, which has been designed as an infrastructure to address the various problems of current internetworking.
