摘要： 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.

摘要： A packet transfer scheme for transferring packets at a boundary of a plurality networks is disclosed. A network interconnection apparatus (router) communicates with a previous hop node in one of the plurality of networks by a first control message including a first identification information for identifying an upstream path from the previous hop node and a specification information for specifying a group of packets to be transferred on the upstream path, and with a next hop node in another of the plurality of networks by a second control message including a second identification information for identifying a downstream path to the next hop node and a specification information for specifying a group of packets to be transferred on the downstream path. Then, the network interconnection apparatus stores a first identifier at a layer lower than layer 3 of the upstream path and a second identifier at a layer lower than layer 3 of the downstream path corresponding to the upstream path, according to the first and second control messages, and transfers a packet from the upstream path to the corresponding downstream path, referring to the memory.
