| Term | Description |
| PPPoE | PPPoE ( Point-to-Point Protocol over Ethernet ) is a method for building PPP sessions and encapsulating PPP packets inside Ethernet frames. PPPoE is used by a number of DSL providers. It requires either routers that have built-in PPPoE support, or PPPoE software to "dial up" and establish the session. Some notable characteristics of a PPPoE connection are that it requires a username/password to connect, and adds an additional 8-byte header to packets, reducing the maximum packet size to 1492 from 1500.
