Point-to-Point Protocol
<communications, protocol> (PPP) The protocol defined in RFC 1661, the
Internet standard for transmitting network layer datagrams (e.g. IP packets)
over serial point-to-point links.
PPP has a number of advantages over SLIP; it is designed to operate both over
asynchronous connections and bit-oriented synchronous systems, it can configure
connections to a remote network dynamically, and test that the link is usable.
PPP can be configured to encapsulate different network layer protocols (such as
IP, IPX, or AppleTalk) by using the appropriate Network Control Protocol (NCP).
RFC 1220 describes how PPP can be used with remote bridging.

Point-to-Point Protocol over Ethernet
<communications, protocol> (PPPoE) The protocol defined in RFC 2516 that
allows one or more computers to connect to the Internet via a shared modem. The
computers connect to the modem via a local area network such as Ethernet and the
modem connects to an Internet Service Provider (ISP) via a serial connection
such as PPP over ADSL.
PPPoE provides each user with a connection that looks and behaves like a
point-to-point dial-up connection even though they are actually sharing an
Ethernet or wireless network. At the same time, the ISP only needs to provide a
single Internet connection, with the same kind of accounting as for PPP. Also,
the IP address is only assigned when the PPPoE connection is open, allowing the
dynamic reuse of IP addresses via DHCP.
PPPoE works by encapsulating PPP frames in Ethernet frames.

Point-to-Point Tunneling Protocol
<communications, protocol> (PPTP) A tunneling protocol for connecting
Windows NT clients and servers over Remote Access Services (RAS). PPTP can be
used to create a Virtual Private Network between computers running NT. It is an
extension of PPP sponsored by Microsoft.
Microsoft Point to Point Encryption may be used with PPTP to provide an
encrypted connection but PPTP itself does not use encryption.
