PPPoE or PPPoA
PPPoA (point-to-point protocol over ATM) and PPPoE (point-to-point protocol over Ethernet)
are authentication and connection protocols used by many service providers for broadband
Internet access. These are specifications for connecting multiple computer users on an Ethernet
local area network to a remote site through common customer premises equipment, which is the
telephone company's term for a customer's modem or similar devices. PPPoE and PPPoA can be
used in connections to offices or buildings. Users may share a common Digital Subscriber Line
(DSL), cable modem, or wireless connection to the Internet. PPPoE and PPPoA combine the
Point-to-Point Protocol (PPP), commonly used in dialup connections, with the Ethernet protocol or
ATM protocol, which supports multiple users in a local area network. The PPP protocol information
is encapsulated within an Ethernet frame or ATM frame.
