Abstract
An ATM network includes a plurality of ATM-LANs which are connected through an ATM-WAN, when a source terminal and a destination terminal belong tb separate ATM-LANs connected through the ATM-WAN, the congestion control is performed as follows. When congestion occurs in an ATM-LAN in which the source terminal exists, the congestion control is performed by the BECN mechanism and when congestion occurs in an ATM-LAN other than the ATM-LAN in which the source terminal exists, the congestion control is performed by the FRP mechanism. When the source terminal and the destination terminal exist in the same ATM-LAN, the congestion control is performed by the FECN mechanism. Thus, in the ATM-LAN, cell loss can be suppressed upon occurrence of congestion.
