Typically, an ISP will only throttle specific ports that are typical for bit-torrent and other peer-to-peer connections. So, one method to bypass is to use a non-standard port for torrent files such as port 21, 20 (ftp) port 8057 (Web Conferencing) 443, 444 (https or Front End Servers). ISP don't usually throttle these because it would result in poor performance for the applications that use them.
