Point-to-Point Protocol for the transmission of multi-protocol datagrams over Point-to-Point links

Status of this Memo This RFC specifies an IAB standards track protocol for the Internet community. Please refer to the current edition of the "IAB Official Protocol Standards" for the standardization state and status of this protocol. Abstract The Point-to-Point Protocol (PPP) provides a method for transmitting datagrams over serial point-to-point links. PPP is composed of three parts: 1. A method for encapsulating datagrams over serial links. 2. An extensible Link Control Protocol (LCP). 3. A family of Network Control Protocols (NCP) for establishing and configuring different network-layer protocols. This document defines the encapsulation scheme, the basic LCP, and an NCP for establishing and configuring the Internet Protocol (IP) (called the IP Control Protocol, IPCP). The options and facilities used by the LCP and the IPCP are defined in separate documents. Control protocols for configuring and utilizing other network-layer protocols besides IP (e.g., DECNET, OSI) are expected to be developed as needed.
