PPP

Point-to-Point Protocol (PPP) is a link layer protocol that carries network layer packets over
point-to-point links. It gains popularity because it provides user authentication, supports
synchronous/asynchronous communication, and allows for easy extension.
PPP contains a set of protocols, including a link control protocol (LCP), a network control protocol
(NCP), and authentication protocols such as Password Authentication Protocol (PAP) and Challenge
Handshake Authentication Protocol (CHAP). Among these protocols,
The LCP is responsible for establishing, tearing down, and monitoring data links.
The NCP is used for negotiating the packet format and type of data links.
PAP and CHAP are for network security.
PAP authentication
PAP is a two-way handshake authentication protocol using plain text passwords. It operates as follows.
1) The requester sends its username and password to the authenticator.
2) The authenticator then checks the local user list to see if the username and password are correct
and returns an acknowledgement or negative acknowledge.
