What are the three methods of broadband authentication?

Three methods of broadband authentication: 1. PPPOE, a point-to-point protocol on Ethernet, is a network tunnel protocol that encapsulates a point-to-point protocol in an Ethernet framework; 2. DHCP, a network protocol for a local area network ; 3. IEEE802.1X is a user authentication technology applied to LAN switches and wireless LAN access points.

#The current main broadband authentication methods are PPPOE, DHCP, and IEEE802.1X. Broadband is a relative description. The larger the frequency range, that is, the higher the bandwidth, the more data that can be sent.

PPPOE

PPPoE (English: Point-to-Point Protocol Over Ethernet), a point-to-point protocol on Ethernet, encapsulates the Point-to-Point Protocol (PPP) on Ethernet A network tunneling protocol in the (Ethernet) framework. 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 Ethernet protocols such as cable modem and digital subscriber line (DSL) to provide users with Access service protocol system.

DHCP

DHCP (Dynamic Host Configuration Protocol) is a network protocol for local area networks. It refers to a range of IP addresses controlled by the server. When the client logs in to the server, it can automatically obtain the IP address and subnet mask assigned by the server. By default, DHCP, as a service component of Windows Server, is not automatically installed by the system and requires administrators to manually install and perform necessary configurations.

IEEE802.1X

IEEE802.1X is one of the LAN standards formulated by the IEEE (Institute of Electrical and Electronics Engineers) 802 Committee. It is a type of LAN switch that is used in and user authentication technology for wireless LAN access points.

IEEE802.1X is a technology that authenticates users before utilizing LAN switches and wireless LAN access points. A regular LAN switch connects cables to the ports to use the LAN. However, a LAN switch that supports 802.1X cannot use the LAN directly after connecting the cable. The LAN can only be used after the connected personal computer has been authenticated and confirmed to be a legitimate user. Through authentication, the LAN switch can pass or block the information sent by the user. Wireless LAN access points also basically use this working principle.
