2.1.3 LAN interconnection using M10 as a bridge
LAN interconnection between a corporate headquarters and its remote
office is another typical application for M10. In the LAN
interconnection application M10 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.
