Exactly, my cable ISP is Cox and they have been traffic shaping for years. That means my neighbor's PornTube traffic already has priority over my FTP session to a clients server.
Its underlying traffic shaping method: at times of congestion,
all “time-sensitive” traffic – which it defines to include Web pages,
voice calls, streaming video, VPN tunneling and games – would not be
delayed. However, less time-sensitive traffic, including FTP transfers,
network storage, P2P, software updates and Usenet groups, could be.
