  • Network system and communication device
    Patent number: 6038215
    Abstract: In the present invention, the first communication device accepting the first LAN and the second communication device accepting the second LAN are connected through the ATM network. When data is transmitted from the second LAN to the first LAN, data transmitted from the second LAN is received by the first communication device through the second communication device and the ATM network, and held by the buffer unit until transmitted to the first LAN by the transmission part. The monitor part the storage quantity of the buffer unit. When the monitor part indicates the possibility that data overflows from the buffer unit, the control data generation part generates control data and transmits it to the second communication device. In the second communication device, the control part obtains the control data and reduces data quantity transmitted from the second communication device to the first communication device based on the control data.
