Point-to-Point Protocol (PPP)
Point-to-Point Protocol (PPP) is a communications protocol for transferring data over point-to-point links established between two networked computers. It is widely used for remote access services and for connecting multiple entities, such as companies, organizations, and people that do not retain a physical connection for a long period of time. PPP is used to establish a reliable connection between two devices over a serial link and to provide a method for exchanging data between them.
PPP is an industry standard protocol that establishes, maintains, and terminates connections between two computers or routers. It uses a combination of structures, functions, and authentication methods to process outgoing and incoming data frames, known as frames, which are sent and received over point-to-point connections. PPP is a layer 2 (data link layer) protocol that runs over asynchronous, synchronous, and ISDN-based circuits or serial communication lines.
PPP is a networking protocol that provides a standard way of delivering data over various technology implementations such as ethernet, cellular phone systems, and satellite broadcast. It is especially useful for creating private, secure networks for remote access applications, such as telecommuting and wild area networks. The PPP standard consists of different components, including Challenge Handshake Authentication Protocol (CHAP), Extensible Authentication Protocol (EAP), and Network Control Protocol (NCP). It also provides a way to negotiate the type of network layer protocols that will be used, such as IP, OSI, and TCP/IP.
PPP works by establishing a data communication link between two computers. This link is referred to as a path and is typically secured through encryption and authentication. The data is then transferred over the link using a series of frames and packets. The two computers then authenticate the connection and establish the parameters that will be used for the exchange of data.
PPP is widely used in modem-to-modem communications and in dial-up networking. It is also frequently used by remote access services to securely connect remote users to corporate networks over public or shared network connections, such as the Internet. Since PPP is a widely recognized standard, it is supported by nearly all modem and router manufacturers. In addition, it is used by many software applications that require a reliable connection between two computers or networks.
The Point-to-Point Protocol can be used to establish a connection between two computers or systems. It uses encryption, authentication, and other protocols to ensure a secure connection over a connection established between two computers. By using the protocol, it is possible to connect devices in a secure manner, even over weak network connections. PPP is a widely accepted protocol for securely connecting two computers or devices over a single communication line, making it an essential element of many networks and services that require a secure connection.
