Acronym for
Point-to-Point Protocol over Ethernet. PPPoE relies on two widely accepted standards:
PPP and
Ethernet. PPPoE is a specification for connecting the users on an Ethernet to the
Internet through a common broadband medium, such as a single
DSL line, wireless device or cable
modem. All the users over the Ethernet share a common connection, so the Ethernet principles supporting multiple users in a
LAN combine with the principles of PPP, which apply to
serial connections.
