Trunking with ATM LANE
Chapter 4, “VLANs and Trunking,” provided a altercation of trunking with assorted forms
of Ethernet links. Trunking, or accustomed assorted VLANs over a distinct link, can additionally be
accomplished application Asynchronous Transfer Mode (ATM). ATM by itself is a connectionoriented
technology congenital aloft relaying beef of data. Therefore, it cannot inherently trunk
VLANs. However, the LAN Emulation (LANE) agreement uses ATM as a agency to mimic
traditional LAN media and can accommodate the trunking function. Multiprotocol over ATM
(MPOA) is addition agreement that extends LANE to action added able aisle selection
through an ATM network. (MPOA is not covered in this book.)
This affiliate presents a analysis of ATM and focuses on the use of LANE technology for
trunking. While ATM is a actual circuitous technology, it is presented alone briefly to set the
foundation for a added abundant altercation of LANE.
