Overview
Point-to-Point Protocol over Ethernet (PPPoE) extends PPP by transporting PPP packets encapsulated in Ethernet over point-to-point links.
PPPoE can provide access to the Internet for the hosts in an Ethernet through a remote access device and implement access control and accounting on a per-host basis. Integrating the low cost of Ethernet and scalability and management functions of PPP, PPPoE gained popularity in various application environments, such as residential networks.
