Method for controlling congestion in connection section between ATM network and NON-ATM network

摘要

Disclosed is a system and a method for controlling a congestion in a connection section between an ATM network and a NON-ATM network that promptly provides information regarding congestion that has occurred in the connection section to the TCP source. If congestion occurs in the connection section receiving the IP packet from the TCP source, the congestion information is marked in the response packet received from the TCP destination and provided to the TCP source so that the operation to avoid the congestion is promptly performed. The congestion information is therefore more current, the congestion can be prevented from being aggravated in the connection section due to the propagation delay and the processing delay.
