PPPoE in IT Glossary

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.
