2.1.3 LAN interconnection using M11 as a bridge
LAN interconnection between corporate headquarters and its remote
office is another typical M11 application. In the LAN interconnection
application, M11 is typically used as an Ethernet bridge which relays
all non-local Ethernet traffic between the corporate headquarters and
remote sites through the ATM core network.
The benefit of bridging in this application example is the transparency
for all network protocols in a multiprotocol data communications
corporate network.
