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.

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 ZyAIR (rather than individual computers), the computers on the

LAN do not need PPPoE software installed, since the ZyAIR 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.
