Abstract: The article presents the implementation technology of PPP protocol over high-speed SDH/SONET fiber networks.PPP software has a lower-level interface with hardware drivers, which processes received PPP packets. The higher-level interfaces include those with network layer protocols such as IP and IPX, which send IP/IPX packets to network layer for further processing, and provide the complete control mechanisms for sending network layer packets. Additionally, we discuss the authentication technique of PPP protocol, which ensures the safety of packets in transit.
