122 Abstract of the Disclosure The object of the present invention is accommodating local connectionless information (data that is immediately transferred without establishing a path to a receive side), such as LAN data in a local area network, by an asynchronous transfer mode (ATM) network using a connection-oriented communication system (which makes data transfers after verifying that a path to the receive side has been established), thereby performing efficient, fast routing of connectionless information. A connectionless communication system of the present invention is equipped with connectionless information cell assembly/deassembly means (30) for bi-directional conversion between variable-length connectionless information and fixed-length connectionless cells, routing control means (31) for analyzing a destination address of information in connectionless cells and controlling the routing of the connectionless cells; and an ATM network (32) for connecting the connectionless information cell assembly/deassembly means (30) and the routing control means (31) by a permanent virtual channel serving as a fixed path and connecting the routing control means together by a virtual channel serving as a semi-fixed 123 path, whereby connectionless information is segmented into connectionless cells and the connectionless information is exchanged within the ATM network in connectionless cell units.
