Point-to-Point Protocol over Ethernet (PPPoE)

PPPoE (Point-to-Point Protocol over Ethernet) is a protocol that is used to establish a point-to-point connection via the Ethernet. PPPoE uses both the standard PPP (Point-to-Point Protocol) and the Ethernet. It is mostly used by providers to ensure dial-up to the Internet via DSL. Ethernet allows several devices to connect simultaneously via PPPoE. When a router is used, it is responsible for ensuring that a connection to the Internet is successfully established.
