Abstract:
A network system comprising a first communication device connected to a first local area network and an Asynchronous Transfer Mode network and a second communication device connected to a second local area network and the Asynchronous Taransfer Mode:said first communication device comprising:buffer means for holding data received from the Asynchronous Transfer Mode network;first transmission means for transmitting the data held by the buffer means to the first local area network;monitor means for monitoring a storage quantity of the data held by the buffer means; andcontrol data generation means for generating and transmitting control data when the monitor means indicates a possibility of a overflow of the data in the buffer means;said second communication device comprising:second transmission means for transmitting data received from the second local area network to the first communication device; andcontrol means for obtaining the control data transmitted from the control data generation means and for reducing a quantity of the data transmitted from the second transmission means based on the control data,wherein said control data generation means generates a control cell by storing the control data and a payload identifier showing that the cell is the control cell in a payload of a cell generated in AAL Type 5 format.
