5.5.5 RFC 1483 Interface (EoA)
The
Ethernet-over-ATM (EoA)
protocol is commonly used to carry data between local
area networks that use the Ethernet protocol and wide-area networks that use the ATM
protocol. Many telecommunications industry networks use the ATM protocol. ISPs who provide
DSL services often use the EoA protocol for data transfer with their customers' DSL modems.
EoA
can be implemented to provide a bridged connection between a DSL modem and the ISP.
In a bridged connection, data is shared between the ISP's network and their customer's as if
the networks were on the same physical LAN. Bridged connections do not use the IP protocol.
EoA can also be configured to provide a routed connection with the ISP, which uses the IP
protocol to exchange data.
