Abstract
Distributed LANs are connected to a wide area network through terminal adapters, which are interconnected by virtual circuits to form a logical bus network. Each terminal adapter copies cells received through the virtual circuit that is allocated for multicasting, and transfers the copied cells to the adjacent terminal adapters via preset virtual circuits. The terminal adapters assemble a part or all of the transmitted message from the received cells and, according to the contents of the assembled message, transfer the copies of the cells to the adjacent terminal adapters through predetermined virtual circuits.
