PPP

In this article we will discuss PPP, will make brief discussion on PPP, In last article we discuss about HDLC.

In computer networking, Point-to-Point Protocol (PPP) is a data link layer (layer 2) communications protocol used to establish a direct connection between two nodes. It connects two routers directly without any host or any other networking device in between.

PPP Stands for “Point-to-Point Protocol.” PPP is a protocol that enables communication and data transfer between two points or “nodes.” For many years,PPP was the standard way to establish a dial-up connection to an ISPs. As dial-up modems were superseded by broadband devices, PPP connections became increasing.

Point-to-Point Protocol or PPP is a layer 2 or data link layer protocol which is used to establish a direct connection between two nodes in a network. It can provide authentication, encryption and compression. This protocol is used to create a simple link between two peers in a network to transport packets.

PPP is a connectionoriented protocol that enables layer two links over a variety of different physical layer connections. It is supported on both synchronous and asynchronous lines, and can operate in half-duplex or full-duplex mode.
