In information communication networks, several control schemes are applied to node systems, circuits, and other equipment, and they interact with each other. So we can say that “information communications,” including telephony, computer communication, and the Internet, are made possible by these complicated control schemes. This paper describes several typical control schemes which are applied in this information communication. First, we classify networks into two-telephone network and IP network- and introduce typical control techniques in these networks. Finally, we also describe examples of congestion control schemes in telephony, VoIP services, and peer-to-peer communications.
