What is Point-to-Point Protocol (PPP)?

PPP is a system that permits data transmission and contact between two endpoints, or locations. PPP was the norm for dial-up connections to Providers for a very long time. PPP links increased as internet devices began to replace dial-up modems. PPP is still used today, though, in "PPP over Ethernet" (PPPoE), a popular Broadband modem connection method.

In the seven-layer OSI architecture, PPP is a data connection mechanism, the second tier. It follows the corporeal layer and encloses the five levels that come before it. This implies that PPP can transmit data over numerous networks, including TCP and UDP, and can be used by a variety of apps. The Internet protocol (IP) is frequently used to transmit data over the Internet.

PPPoE

PPPoE, also known as PPP over Ethernet, is a widely used method of connecting to a Provider with a Broadband connection. It enables high-speed Ethernet socket connections between your modem and a PC or gateway. A point-to-point link is then established between the router and the Provider. You might be prompted for a login and password in the PPPoE options since PPP allows verification. Your Broadband Internet supplier can easily verify that you are a legitimate user using this information.

PPTP

PPP can be used for data routing, or safely moving data within the PPP protocol, because it incorporates other protocols. To accomplish this, virtual private networks (VPNs) are frequently built using the Point-to-Point Tunneling Protocol (PPTP), which was created for this reason. PPP, however, has some documented security flaws and was not initially intended to be a safe system. So, new VPNs frequently employ different algorithms.
