However, peer-to-peer (P2P) file sharing and high-quality streaming video can require high data-charges for prolonged durations, which violates these assumptions and might cause a service to become oversubscribed, resulting in congestion and poor performance. The TCP protocol contains move-management mechanisms that mechanically throttle back on the bandwidth getting used during times of network congestion. This is truthful in the sense that each one customers that have congestion receive less bandwidth, but it can be irritating for patrons and a significant downside for ISPs.
