3.5.2 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.
