3.4.3 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 xDSL, cable, wireless, etc.) to achieve access to high-speed data networks. It preserves
the existing Microsoft Dial-Up Networking experience and requires no new learning or procedures.
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.
