PPP Point to Point Protocol
The Point-to-Point Protocol (PPP) is a widely used data link layer protocol for establishing a direct connection between two nodes over a serial link. It was originally developed for use with dial-up connections, but is now also used with other WAN technologies, such as leased lines and ISDN connections.
PPP provides several important features for establishing and maintaining a reliable, secure communication link between two nodes. These include:
Authentication: PPP supports various methods of authentication, such as Password Authentication Protocol (PAP) and Challenge Handshake Authentication Protocol (CHAP), to ensure that only authorized users can access the network.
Error detection and correction: PPP uses a cyclic redundancy check (CRC) to detect errors in transmitted data, and can request retransmission of data that is received with errors.
Compression: PPP supports compression of data to reduce the amount of data that needs to be transmitted, which can improve performance over low-speed connections.
Multilink support: PPP can support the use of multiple physical links to establish a single logical connection, which can increase bandwidth and improve fault tolerance.
PPP frames consist of a header, a data field, and a trailer. The header contains control information, such as the frame type and sequence number, while the data field contains the actual data being transmitted. The trailer contains error detection and correction information.
One of the advantages of PPP is that it is a widely supported and standardized protocol, which means that devices from different vendors can communicate with each other using PPP frames. It is also a very reliable protocol, with built-in error detection and correction mechanisms that ensure data integrity during transmission.
