ABSTRACT:
A packet directional path identifier transfer system contains on the transmission side thereof, a means 2 of converting packet directional path identifier data into bit map information in which an address of each bit corresponds to a packet directional path identifier. The system contains on the reception side thereof, a means 5 for inversely converting the bit map information of the packet directional path identifier data to the packet directional path identifier data. Otherwise, the system further contains on the transmission side thereof, means 8 and 10 for determining the top and bottom values of the packet directional path identifier data to be transmitted, and a means 9 for converting the packet directional path identifier data between the top and bottom values into bit map information, and at the reception side thereof, a means 13 for inversely converting into the initial packet directional path identifier data the bit map information of the packet directional path identifier between the top and bottom values. Further, the top value of the identifier(s) of the newly-set packet directional path(s) determined from the non-used packet directional path identifier(s) in the outgoing packet directional path of the transmission-side node and the number of the newly-set packet directional path identifier(s) are transmitted, and a reference is made to the incoming packet directional path identifier table at the reception-side node to recognize the newly-set packet directional path(s) based on the information received. (FIGS. 1 and 2.)
