protocol is the second layer (data link layer) of OSI basic reference model, and it can
be used not only via IP network but also via various paths such as frame relay and
ATM.
PPPoE
(PPP over Ethernet)
This enables the use of PPP (needed for calls for phone and ISDN lines) in “constant
connection” environment such as LAN.
