![]() ![]() ![]() PPP provides a method for transmitting datagram over serial point-to-point links. In addition to IP, PPP supports other protocols, including Novell’s Internetwork Packet Exchange (IPX) and DECnet. PPP supports these functions by providing an extensible Link Control Program (LCP) and a family of Network Control Program (NCP) to negotiate optional configuration parameters and facilities. PPP also established a standard for the assignment and management of IP address, synchronous (start/stop) and bit-oriented synchronous encapsulation, network protocol multiplexing, link configuration, link quality testing, error detection, and option negotiation for such capabilities as network layer address negotiation and data compression negotiation. Encapsulation is the process of storing packets from the foreign protocol inside PPP frames. PPP was designed to enable the transmission of different protocols over one point-to-point link by utilizing encapsulation. ![]() Although PPP is primarily used over dialup lines, variants such as PPoE (PPP over Ethernet) and PPoA (PPP over ATM) extend PPP to new data-link layer protocols. PPP (Point-to-Point Protocol) is the most widely used method for transporting IP packets over a serial link between the user and the Internet Service Provider (ISP). ![]()
