    • A traffic control method can prevent that the number of cells transmitted to an ATM network exceeds a maximum transmission rate. When a frame F is transmitted from a frame relay network FR1 to an IWF, a traffic control part included in the frame relay network FR1 measures the transmission data quantity for a measuring time in a DLCI connecting the frame relay network FR1 and the IWF. Successively, the traffic control part detects a traffic restrictive level corresponding to the measured transmission data quantity. Then, the traffic restrictive process corresponding to the restrictive level is performed, and the frame transmission is controlled by the transmitted terminal of the frame F. Thus, it is prevented that the number of cells transmitted to the ATM network exceeds a determined maximum transmission rate.
    • 流量控制方法可以防止发送到ATM网络的小区的数量超过最大传输速率。 当帧F从帧中继网络FR 1发送到IWF时,包括在帧中继网络FR1中的业务控制部分测量连接帧中继网络FR 1和连接帧中继网络FR 1的DLCI中的测量时间的发送数据量 IWF。 接下来,交通控制部分检测与所测量的发送数据量对应的交通限制级别。 然后,执行与限制级别对应的流量限制处理,并且由帧F的发送终端控制帧发送。因此,防止发送到ATM网络的小区数超过确定的最大传输速率 。
