PPP

Point-to-Point Protocol (PPP), is a protocol for communication between
two computers using a serial interface, for instance, a dialup connection
where a personal computer is connected by telephone line to a server.
The ISP provides the user with a PPP connection so that the provider's
server can respond to the user's requests, pass them on to the Internet, and
forward requested Internet responses back to the user. Relative to the OSI
reference model, PPP provides Layer 2 (data-link layer) service.
At Layer 2, PPP defines an encapsulation mechanism to support
multi-protocol packets to travel through IP networks. It starts with a Link
Control Protocol (LCP) for link establishment, configuration and testing.
Once the LCP is initialized, one or several Network Control Protocols
(NCPs) can be used to transport traffic for a particular protocol suite, so
that multiple protocols can interoperate on the same link, for example,
both IP and IPX traffic can share a PPP link.
Authentication is available as an option for PPP communications. The
authentication protocols that PPP currently supports include:
Password Authentication Protocol (PAP)
Challenge Handshake Authentication Protocol (CHAP)
Microsoft CHAP version 1
Microsoft CHAP version 2
If authentication is used, at least one of the peers has to authenticate itself
before the network layer protocol parameters can be negotiated using NCP.
During the LCP and NCP negotiation, optional parameters such as
encryption, can be negotiated. When LCP and NCP negotiation is done, IP
datagrams can be sent over the link. More about the application and
security of PPP can be found in section
