<p>PURPOSE:To secure the transfer time of each data and to equalize the load of junction lines and repeating stations by determining a repeating route for call setting in accordance with the repeating route selection probability where contents of transmission data and the actual load state are taken into consideration. CONSTITUTION:Repeating routes 20, 21, and 22 are used to periodically transmit a transfer time measuring packet from an originating station to a terminating station, and the terminating station adds the reception time of each packet to return it. The originating station receives it to calculate the transfer delay time by the difference between the transmission time and the incoming time and sets a transfer margin time to columns 52 and 53 of a pertinent repeating route in a transfer time table 50. The value obtained by dividing the transfer margin time by the total of transfer margin times of all repeating routes is set as a selection probability 54 of the pertinent repeating route. When a new call will be set, a repeating route is determined based on selection probabilities 54. Thus, calls and the load in a network are equalized and the transfer delay time is satisfied.</p> |
