Abstract
A plurality of datagram VCCs, each of which is exclusively for connectionless transfer of data, are established between mutually adjacent exchanges in advance, one of these datagram VCCs is assigned exclusively for connectionless data communication and connectionless communication is performed using this datagram VCC. Specifically, an originating terminal disassembles connectionless data into data cells, inserts a cell (a leading cell), which indicates the destination address of a terminal that is the destination of the data, at the head of the data cells and then sends the leading cell to the exchange prior to the data cells. The exchange assigns a prescribed datagram VCC for connectionless communication upon referring to the destination terminal address indicated by the leading cell and thenceforth uses this VCC to transmit data cells having line identifier identical with that of the leading cell.
