ABSTRACT:
When a data transmission request is generated, a transmission capable counter indicative of a data length C1 of data which can be transmitted at a certain time point is checked and, when a count value is positive, transmission data Cs is subtracted from the value of the transmission capable counter and a transmitting process is started by a line transmission processing section. When the value C1 of the transmission capable counter is negative or 0, the transmission data is held in a transmission holding data queue. When a fundamental timer times out, if the value C1 of the transmission capable counter is positive, a value C2 of a transmission throughput counter is preset. If the value C1 of the transmission capable counter is negative or 0, the value C2 of the transmission throughput counter is added to the value C1 of the transmission capable counter. Thus, a throughput of the transmission data from the self station is dynamically changed in accordance with a communication capacity and a performance which momently change in a communication network using a frame relay protocol.
