PPTP
What is PPTP?
PPTP (Point-to-Point Tunneling Protocol) is a Microsoft proprietary protocol
(RFC 2637 for PPTP is informational only) to tunnel PPP frames.
How can we transport PPP frames from a PC to a broadband
modem over Ethernet?
A solution is to build PPTP into the ANT (ADSL Network Termination) where
PPTP is used only over the short haul between the PC and the modem over
Ethernet. For the rest of the connection, the PPP frames are transported with PPP
over AAL5 (RFC 2364) The PPP connection, however, is still between the PC and
the ISP. The various connections in this setup are depicted in the following
diagram. The drawback of this solution is that it requires one separate ATM VC
per destination.
