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 benefi ts 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 specifi c users.
Operationally, PPPoE saves signifi cant effort for both the subscriber
and the ISP/carrier, as it requires no specifi c confi guration of the
broadband modem at the subscriber’s site.
By implementing PPPoE directly on the WR1500 Wireless Router
(rather than individual computers), the computers on the LAN do not
need PPPoE software installed, since the WR1500 Wireless Router
does that part of the task. Furthermore, with NAT, all of the LAN’s
computers will have Internet access.
Refer to the manual on the CD ROM for more information on
PPPoE, and to the next page for setup details.
