Abstract
Data communication is achieved between different LAN segments without passing the data through a router. A cell segmentation selector selects either LAN emulation or native-mode ATM for a packet made at an upper level protocol higher than a network layer. A LAN emulator makes an ATM cell from the MAC frame after the packet is made with a MAC frame. The native-mode ATM unit directly makes the ATM cell from the packet. Either the LAN emulation or the native-mode ATM is selected for operation by the cell segmentation selector. Then, the ATM cell is made by the LAN emulator or the native-mode ATM unit with reference to the selection and then the data communication is carried out using the produced ATM cell.
