Abstract
The Point-to-Point Protocol (PPP) provides a standard method for
transporting multi-protocol datagrams over point-to-point links. PPP
is comprised of three main components:
1. A method for encapsulating multi-protocol datagrams.
2. A Link Control Protocol (LCP) for establishing, configuring,
and testing the data-link connection.
3. A family of Network Control Protocols (NCPs) for establishing
and configuring different network-layer protocols.
This document defines the PPP organization and methodology, and the
PPP encapsulation, together with an extensible option negotiation
mechanism which is able to negotiate a rich assortment of
configuration parameters and provides additional management
functions. The PPP Link Control Protocol (LCP) is described in terms
of this mechanism.
