Overview of PPPoE Access

Overview of PPPoE Access


Point-to-Point Protocol over Ethernet (PPPoE) is a link-layer protocol that transmits PPP datagrams through PPP sessions established over point-to-point connections on Ethernet networks. As a supplementary protocol of PPP, PPPoE provides access services for users on Ethernet networks, and implements user control and accounting.


As data services develop, the number of broadband users is growing explosively. To facilitate broadband user access, carriers employ a variety of access modes, such as x digital subscriber line (xDSL), local area network (LAN), hybrid fiber coaxial (HFC), and wireless. To build an operable, manageable, and profitable broadband network in such a context, efficient user management is a key factor. PPPoE effectively resolves issues such as user access and accounting, and is popular among broadband access carriers.

PPPoE access has the following advantages:
  • Multi-protocol transmission

    PPP data packets are transmitted over Ethernet. In addition to IP, PPP data packets can have other types of protocols encapsulated, even link-layer protocols, such as Ethernet.

  • Flexible accounting

    PPPoE access provides rich accounting data, such as the numbers of incoming and outgoing packets and bytes, and start and end time of connections.

  • IPv4/IPv6 dual stack

    PPPoE access supports allocation of both IPv4 and IPv6 addresses.


PPPoE access brings the following benefits to carriers:

  • Remote user access over Ethernet

  • Flexible access control and accounting
