3.3.2 PPPoE Encapsulation

Point-to-Point Protocol over Ethernet (PPPoE) functions as a dial-up connection. PPPoE is an
IETF (Internet Engineering Task Force) draft standard specifying how a host personal
computer interacts with a broadband modem (for example DSL, cable, wireless, etc.) to
achieve access to high-speed data networks.

For the service provider, PPPoE offers an access and authentication method that works with
existing access control systems (for instance, Radius). For the user, PPPoE provides a login
and authentication method that the existing Microsoft Dial-Up Networking software can
activate, and therefore requires no new learning or procedures for Windows users.

One of the benefits of PPPoE is the ability to let end users access one of multiple network
services, a function known as dynamic service selection. This enables the service provider to
easily create and offer new IP services for specific users.

Operationally, PPPoE saves significant effort for both the subscriber and the ISP/carrier, as it
requires no specific configuration of the broadband modem at the subscriber’s site.

By implementing PPPoE directly on the Prestige (rather than individual computers), the
computers on the LAN do not need PPPoE software installed, since the Prestige does that part
of the task. Furthermore, with NAT, all of the LAN's computers will have Internet access.

Refer to the appendix for more information on PPPoE.
