Next, PPP (Point-to-Point Protocol) mentioned in the above technical problem will be briefly described.

PPP is a communication protocol for wide area network (WAN) that is used to communicate data between two points. It corresponds to the data connection layer (second layer) of the open systems interconnection (OSI) basic reference model. Most routers in the local area network (LAN) access devices support PPP. PPP includes a function that compresses only the header portion of a data packet or authentication protocols such as a password authentication protocol (PAP) or a challenge-handshake authentication protocol (CHAP) so that these functions can be used when establishing a connection. It also has the capability of the Internet Protocol Control Protocol (IPCP), which allows an access server to automatically assign an IP (Internet Protocol) address to a client personal computer when connecting to a remote LAN. Dial-up IP connections that connect to servers of Internet Information Providers (ISPs) through public networks, such as public telephone networks or Integrated Services Digital Networks (ISDN), typically use IPCP over PPP connections, so users do not have to obtain global IP addresses. . PPP is defined in RFC 1171 as a representative protocol for dial-up IP access.
