Abstract:
In a network including a processing device coupled to an asynchronous transfer mode (ATM) network and an Ethernet network, the ATM network configured to provide local area network emulation (LANE) services, a method for forwarding a packet received by the processing device from the Ethernet network, comprising:reading header information from a header of the received packet, the header information including a packet type, a destination media access control (MAC) address, and a virtual LAN identifier (VLAN ID); storing in a memory coupled with the processing device LANE emulation client (LEC) information for LECS coupled with the ATM network, the LEC information including LEC IDs for the LECs; determining if the packet type is of type LANE or virtual LAN (VLAN); and if packet type is of type LANE or VLAN: determining a LEC ID for the packet from the LEC information based on the VLAN ID; determining virtual channel connection (VCC) information corresponding to the destination MAC address of the packet; and forwarding the packet to its destination based on the VCC information and the LEC ID for the packet.
