Abstract:
A Broadcast and Unknown Server (BUS) entity for use in an Asynchronous Transfer Mode (ATM) network including one or more LAN Emulation Clients (LECs), said BUS entity comprising:a BUS manager adapted to establish a Multicast Send Virtual Channel Connection (VCC) and a Multicast Forward VCC to one or more LECs and to establish coupling VCCs between a BUS engine and said Multicast Send and Multicast Forward VCCs; an ATM switch matrix adapted to forward traffic received over said Multicast Send VCC to said BUS engine via a coupling VCC, and to forward traffic received from said BUS engine via a coupling VCC to said Multicast Forward VCC; and said BUS engine adapted to assemble Ethernet frames from ATM cell traffic received from said Multicast Send VCC via said coupling VCC and to forward the assembled Ethernet frames to one or more Ethernet ports configured in loopback, said BUS engine adapted to segment Ethernet frames received over said loopback into ATM cells and to forward said ATM cells to said Multicast Forward VCC via said coupling VCC.
