Point-to-Point Tunneling Protocol (PPTP)
(I) An Internet client-server protocol (originally developed by
Ascend and Microsoft) that enables a dial-up user to create a
virtual extension of the dial-up link across a network by
tunneling PPP over IP. (See: L2TP.)
(C) PPP can encapsulate any Internet Protocol Suite network layer
protocol (or OSI layer 3 protocol). Therefore, PPTP does not
specify security services; it depends on protocols above and below
it to provide any needed security. PPTP makes it possible to
divorce the location of the initial dial-up server (i.e., the PPTP
Access Concentrator, the client, which runs on a special-purpose
host) from the location at which the dial-up protocol (PPP)
connection is terminated and access to the network is provided
(i.e., the PPTP Network Server, which runs on a general-purpose
host).
