Abstract
A large capacity connectionless communication system and a method of large capacity connectionless communication, capable of achieving an application to both a public network and a private network by centralizing connectionless data in asynchronous transfer mode network and carrying out a routing of the centralized connectionless data by use of a separate connectionless cell switching unit having a rapid connection setup function and a function for maintaining the set-up connection. The connectionless communication system includes terminals each adapted to perform a function of converting a connectionless frame received from a network into a cell and reversely converting the cell into the original frame, request a setup of a virtual connection when the frame is generated, and output the cell by use of a virtual channel identifier value indicative of the set-up virtual connection, and connectionless data service units each adapted to set up the virtual connection at the request of the terminal, transfer the set-up virtual channel identifier value to the terminal which has requested the virtual connection setup, and perform a function of switching the cell transferred from the termin…
