Abstract
A device and a scheme for realizing the bridge interconnection in the ATM network efficiently. In the bridge device, a MAC frame transmitted from the interface with respect to the ATM network is transmitted selectively to either a point-to-point ATM connection interconnecting this bridge device and another bridge device or a multicast ATM connection interconnecting this bridge device and other bridge devices, while MAC addresses and identifiers of point-to-point ATM connections are registered in correspondences in a table. In a case this bridge device directly accommodates emulation hosts for emulating another non-ATM network through ATM connections having this bridge device as a starting point, a type of a MAC frame entered from the interface with respect to the ATM network is identified as either a MAC frame transmitted from any of the emulation hosts or a MAC frame transmitted from another bridge device connected with this bridge device by a bridge connection through the ATM network, and the MAC frame entered from the interface is transmitted selectively to ATM connections of the ATM network according to the identified type.
