A CDE Definition
(1) (lane) A channel in the PCI Express interface. See PCI Express.
(2) (LAN Emulation) Connecting Ethernet and Token Ring networks together via ATM. LANE was also used to create emulated LANs (ELANs), which like VLANs, logically combine groups of users. Governed by the ATM Forum, the LANE User-to-Network Interface (LUNI) defined how end stations communicated with the ATM network.
Encapsulating LAN Packets
The LANE driver encapsulated Ethernet and Token Ring packets into LANE packets and then converted them into ATM cells, and vice versa. The driver resided in each client station and in an edge device between the LAN and the ATM switch.
The LECS and BUS
Implemented in an ATM switch or stand-alone server, LANE comprised two software components: the LANE Configuration Server (LECS) for address resolution, and the Broadcast and Unknown Server (BUS) for multicast and broadcast traffic management within the ELAN. See ATM and MPOA.
