4.7.3 ATM TR/Ethernet Bridge Module and LAN Emulation

The ATM TR/Ethernet Bridge Module provides connectivity between traditional LANs (token-ring or Ethernet) and ATM networks by sending LAN frames transparently over the ATM network using LAN emulation to resolve

MAC-to-ATM addresses.

The IBM LAN emulation service allows the ATM network to emulate the services of either a token-ring or an Ethernet LAN. The LAN emulation service is provided jointly by a LAN emulation server (LE server) and the LAN emulation client (LE client) software running in the device attached to the ATM network.

As an LE client, the ATM TR/Ethernet Bridge Module is able to find the correct ATM destination, to set up the connection, and to switch LAN traffic to that destination on behalf of a LAN endstation. It is self-learning, meaning that it is able to discover its ATM partners and to establish connections on an as-needed basis.
