Point-to-Point Tunneling Protocol (PPTP)

A call-control and management protocol that allows a PPTP Network Server to control access by dial-in circuit switched calls received by a PPTP Access Concentrator. It provides flow and congestion controlled encapsulation datagram service for carrying Point-to-Point Protocol packets. While PPTP does not provide encryption it can be used in conjunction with encryption to provide a Virtual Private Network over the Internet between an individual dialup user and a LAN or WAN.
