Abstract
An IP datagram transmission technique in an ATM network. A DSUcomprises a selecting unit selecting a type of distribution representing distribution of a packet having a transmission source address to either bridging or routing, a bridging processor bridging the packet to generate a packet when bridging is selected, a routing processor routing the packet to generate a packet when routing is selected, and an ATM terminating unit encapsulating the packet to generate an ATM cell, thereby automatically discriminating between bridging and routing. Accordingly, the user can simultaneously connect to a plurality of Internet service providers to receive different service modes.
