PPPoE uses Ethernet networking with PPP in an encapsulation
scheme designed for multi-PC homes and small businesses.
PPPoE enables multiple PCs to connect to multiple destinations
through a single, shared CPE using one PVC. This is based on
the standard RFC 2516 'PPP over Ethernet'.

4.1.4 PPP over ATM (PPPoA)

PPPoA has a great advantage in reducing the overhead required in
PPPoE. It is based on the standard RFC 2364 'PPP over AAL 5'.
