What is the protocol corresponding to dial-up networking?

The protocol corresponding to the dial-up network is PPPoE.

PPPoE (English: Point-to-Point Protocol Over Ethernet), a point-to-point protocol on Ethernet, is a network tunnel that encapsulates the Point-to-Point Protocol (PPP) in an Ethernet framework. protocol.

Since the PPP protocol is integrated into the protocol, it can realize authentication, encryption, compression and other functions that traditional Ethernet cannot provide. It can also be used for cable modem and digital subscriber line (DSL), etc. Ethernet protocol is a protocol system that provides access services to users.

Essentially, it is a protocol that allows the creation of point-to-point tunnels between two Ethernet interfaces in an Ethernet broadcast domain.

Taking pppd commonly used in Linux systems as an example, it supports IP, IPv6 and IPX network layer protocols on the PPP interface.

It uses traditional PPP-based software to manage a connection that does not use serial lines but a directed packet network similar to Ethernet. This standard connection with login and password facilitates billing by the access provider. Furthermore, the other end of the connection only assigns an IP address when the PPPoE connection is established, thus allowing dynamic reuse of IP addresses.

PPPoE is developed by UUNET, Redback Networks and RouterWare. Published in RFC 2516 description.
