What does PPPOE mean?

Point-to-point protocol over Ethernet
The Point-to-Point Protocol over Ethernet is a network protocol for encapsulating PPP frames inside Ethernet frames. It is used mainly either: ⁕with PPPoE-speaking Internet DSL services where a PPPoE-speaking modem-router connects to the DSL service. Here both ISP and modem-router need to speak PPPoE. ⁕or when a PPPoE-speaking DSL modem is connected to a PPPoE-speaking Ethernet-only router using an Ethernet cable. For such two-box systems, DSL modem plus Ethernet-only router, PPPoE is now the preferred solution. In fact, the term ‘PPPoE’ is used sometimes confusingly to refer to either or both of two things: a modem-to-router protocol; on the DSL side of things, a part of a protocol stack which is PPPoEoA.; or both and chained together. It is possible to find DSL modems, such as the Draytek Vigor 120, where PPPoE is confined to the ethernet link between a DSL modem and a partnering router, and the ISP does not speak PPPoE at all. However the case with a PPPoE-speaking service from an ISP is far more common.
