Application of PPP protocol

PPP protocol is one of the most widely used protocols in the WAN, which has the advantages of simple, user-authentication capability, and can solve IP assignment.

A home dial-up is a communication link between the client and the operator's access server via PPP. At present, broadband access is becoming the trend to replace dial-up Internet, in the rapid development of broadband access technology today, PPP also derived new applications. Typical applications are in ADSL (asymmetric data subscriber loop, asymmetrical Digital subscriber loop) access mode, PPP and other protocols together derive a new protocol that meets the requirements of broadband access, such as PPPoE (PPP over Ethernet), PPPoA (PPP over ATM).

Using Ethernet (Ethernet) resources, the way that PPP is run on the Ethernet network for user authentication access is called PPPoE. PPPoE is the protection of the user's Ethernet resources, and the completion of the ADSL access requirements, is currently the most widely used ADSL access technology standards.

Similarly, in the ATM (Asynchronous transfer mode, asynchronous Transfer mode) network, the way the PPP protocol is run to manage user authentication is called PPPoA. It is the same as the principle of PPPoE, and the difference is that it is on an ATM network, and PPPoE is running on an Ethernet network, so you have to adapt to ATM standards and Ethernet standards, respectively.

The simple and complete PPP protocol has made it widely used, and it is believed that it can play a more important role in the future development of network technology.
