Stands for “Point-to-Point Protocol.” PPP is a protocol that permits communication and knowledge switch between two factors or “nodes.” For a few years, PPP was the usual technique to set up a dial-up connection to an ISPs. As dial-up modems have been outmoded by broadband gadgets, PPP connections grew to become growing. However, PPP lives on in “PPP over Ethernet” (PPPoE), which is a typical method to hook up with the Internet using a DSL modem.

PPP is an information hyperlink protocol, which is the second layer of the seven-layer OSI mannequin. It comes simply after the bodily layer and encapsulates the 5 layers beneath it. This means PPP can be utilized by a number of purposes and will switch knowledge over a number of protocols, reminiscent of TCP and UDP. It generally makes use of the Internet protocol (IP) to switch knowledge over the Internet.


Because PPP encapsulates different protocols, it may be used for knowledge tunneling, or securely transferring knowledge throughout the PPP protocol. The Point-to-Point Tunneling Protocol (PPTP was designed for this objective and is usually used to create digital non-public networks VPNs. However, PPP was not initially designed as a safe protocol and has some identified safety vulnerabilities. Therefore trendy VPNs usually use different protocols.


PPPoE, or PPP over Ethernet, is an ordinary method to hook up with an ISP using a DSL modem. It lets you join your modem to a pc or router using a high-speed Ethernet port. The modem then establishes a point-to-point reference to the ISP. PPP helps authentication, so chances are you’ll be requested to enter a username and password within the PPPoE settings. This data supplies a easy method on your DSL Internet supplier to verify you’re a legitimate subscriber.
