TRANSMISSION CONTROL FOR MINIMIZING CONGESTION IN DIGITAL COMMUNICATIONS NETWORKS

摘要

In congestion control in a digital communications network such as the Internet or corporate "Intranets", and especially in real-tine transmissions in such networks, perfect reliability may not be required. For increased likelihood that data arrive on time, an estimate is used of the bandwidth which is available from a sender to a receiver. The estimate is increased or decreased, by the sender, depending on monitoring of acknowledgemnts from the receiver. The technique coexists well with protocols based on TCP (Transmission Control Protocol), such as FTP (File Transfer Protocol) and HTTP (Hyper Text Transfer Protocol), by sharing the available bandwidth equally.
