Abstract
A novel BUS entity utilizing the forwarding engine in a conventional LAN switch incorporating an ATM interface. The forwarding engine is adapted to assemble Ethernet frames from ATM cells and to segment Ethernet frames back to ATM cells. The switching fabric in a conventional LAN switch is adapted to perform the segmentation and re-assembly (SAR) function of the BUS whereby ATM cells are assembled into Ethernet frames, switched and segmented back to ATM cells. In operation, one or more Multicast Send VCCs transmit traffic destined for the BUS to the modified LAN switch of the present invention. The switching fabric is configured to switch the received traffic to an appropriate outbound Etheret port. The outbound Ethernet port is looped backed to itself and input to the switching fabric. Switching fabric is configured to output the traffic to the appropriate Multicast Forward VCC for distribution to the LECs.
