PPPoA / PPPoE
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 modem and similar devices. PPPoE and PPPoA can
be used to office or building. Users 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.
