IPoE takes DHCP (Dynamic Host Configuration Protocol) as the core and closely combines with RADIUS (Remote User Dial-in Authentication Protocol) to realize the broadband access authentication system of IP user session mechanism, IP data stream classification mechanism, IP session authentication and management mechanism. IPoE can not only meet QoS (Quality of Service) differentiated services, but also has the characteristics of efficient multicast.

PPPoE (Ethernet Point-to-Point Protocol) can connect Ethernet hosts to remote access hubs through simple bridging devices. Through PPPoE protocol, remote access equipment can control and charge each access user.

Extended data:

In the application of IPTV, the set-top box has passed the IPoE authentication, and the Discover sent by it contains option 60, indicating that it is a set-top box. After receiving this Discover, Bras will create a virtual interface for this user, then add Option 82 after Discover and send it to DHCP server.

After receiving this request, the DHCP server will strip option 60 and option 82 and send the information to Radius. Radius authentication found that this was a set-top box and knew its online time and location. After successful authentication, the DHCP server will return to accept, and then the DHCP server will complete the provision. Finally, the set-top box obtains the IP address.
