Point to Point Protocol

Point-to-Point Protocol
encapsulation protocol for transporting IP traffic over point-to-
point links. PPP also established a standard for assignment and
management of IP addresses asynchronous (start/stop), bit-
oriented synchronous
multiplexing, link
negotiation and data-compression negotiation.
PPP supports these functions by providing an extensible Link
Control Protocol (LCP) and a family of Network Control Protocols
(NCPs) to negotiate optional configuration parameters and
facilities. In addition to IP, PPP supports other protocols,
including Novell's Internetwork Packet Exchange (IPX) and
DECnet.
PPP provides a method for transmitting datagram's over serial
point-to-point links. PPP contains three main components:
A method for encapsulating datagram's over serial links. PPP
uses High-Level Data Link Control.
(HDLC) protocol as a basis for encapsulating datagram over
point-to-point links.
An extensible LCP that establishes, configures, and test the
data link connection.
A family of NCPs for establishing and configuring different
network layer protocols. PPP is designed to allow the
simultaneous use of multiple network layer protocols.
PPP uses principles, terminology and frame structure of
International Organization for Standardization (ISO) HDLC
procedures (ISO 3309-1979 Transmission." ISO 3309-1979
specifies HDLC frame structure for use in synchronous
environments.
ISO 3309:1984/PDAD1 specifies proposed modifications to
ISO 3309-1979
environments. PPP control procedures use definitions and
control field encodings standardized in ISO 4335-1979 and
ISO 4335-1979/Addendum
appears in Figure 73.
