Abstract
In LAN interconnect, it is necessary to perform route discovery to locate a destination device. A novel method of selecting designated source routing bridges and a new single-route broadcast scheme using those selected bridges are disclosed. The invention makes use of intelligent source routing bridges which connect LAN segments. In order to configure a single-route broadcast path to each connected LAN, a selection procedure is performed among source routing bridges according to the present invention to ensure that there is only one path between two connecting LAN segments. In one embodiment, a packet switching network is used as a WAN which interconnects many LAN segments by way of a virtual ring created in the WAN and the present invention chooses only one path between the individual LAN segment and the virtual ring.
