<p>PURPOSE:To prevent the influence of a convergence to the inclination of a traffic between data having different high order layer control by classifying plural links into two groups or above and providing a data receiving buffer for a line control device and for a group in a processing device. CONSTITUTION:Receiving buffers 311, 312, 3n1 and 3n2 in a processing device are assigned to a line control device unit and a service access point unit. Thus, by assigning the receiving buffers 311, 312, 3n1 and 3n2 in the processing device to the line control device unit and the service access point unit, line control devices 11,..., 1n use the assigned receiving buffer, and therefore, the receiving buffer hunting competition with other line control device does not occur. Since the receiving buffer is assigned to a service access point unit, the straddle of different high order layer control parts 41 and 4n at the time of reading the data in the receiving buffer is not needed.</p> |
