PPPoATM (PPP over ATM)
PPP over ATM - RFC 2364
PPP over ATM (PPPoATM) is the most elegant and simple implementation that provides PPP
encapsulation over a routed ADSL connection.
Microsoft provides a PPP over ATM stack in Windows 98 Second Edition, Windows Me
® ®
and Windows 2000 and this provides an almost ideal implementation for 'passive' ADSL
®
modems such as internal cards and USB devices.
PPPoE (PPP over Ethernet)
PPP over Ethernet (PPPoE) is used in some existing ADSL services. It requires a custom
'driver' in the user's PC, similar manner to Dial-Up Networking. In other words, you will
be dependent on the PPP over Ethernet (PPPoE) client being available for your operating
system platform.
Protocol
In information technology, a protocol is a special set of rules, procedures and conventions
that two end points in a telecommunication connection use when they communicate.
PVC
PVC, Permanent Virtual Circuit, is an ATM virtual circuit established on top of your ADSL
connection from your router to your ISP. The call set-up and tear-down are not visible, which
creates the feeling of having a dedicated connection to the Internet.
