Hi smart people,

If I have several computers on my home network and I have not set any explicit QoS rules on my router, how is bandwidth allocated? For example, if computer 1 is downloading a torrent at max speed and a second computer starts a download, how is the bandwidth allocation between the two determined? Thanks!

If you want a really in-depth description, this article will give it to you. https://en.wikipedia.org/wiki/TCP_congestion_control

Your torrenting might not be using TCP, but the basic idea is the same.

TL;DR: the router uses some math and so forth to tell both computers to slow down to the point that it's not overloaded.
