On a transmission side, provided is a means (2) which converts the discriminative information data on packet routes into the information of a bit map, the address of whose individual bit corresponds to the discriminative information on the packet routes. On a reception side provided is a means (5) which converts inversely, the information of the bit map, which is concerned with the discriminative information data on the packet routes, into the discriminative information data on the packet routes. Alternatively, further, on the transmission side, provided are means (8, 10) for inquiring the forefront and last value of the transmitted discriminative information data on a packet route respectively. Also, provided is a means (9) for converting, the discriminative information data on the packet route between the forefront and last value, into the information of the bit map. In this case, on the reception side, provided are means (13, 14) for converting, the information of the bit map, which is concerned with the discriminative information data on the packet route between the forefront and last value, into the original discriminative information data on the packet route. Further, determined is the discriminative information on the forefront packet route to be preset newly, according to the discriminative information on the idle packet route in a discriminative information table, which is concerned with the packet routes outputted from transmission side nodes. Then, the discriminative information about this forefront and other packet routes is transmitted. On the reception side, from the transmitted information, referring to a discriminative information table, which is concerned with the packet routes inputted to reception side nodes, the discriminative information on the new packet route is recognized. <IMAGE> |
