摘要 研究了PPP协议在高速SDH/SONET光纤网络上的实现技术,并将其应用到高速路由器的工程实践中.实现的PPP协议软件向下和底层硬件驱动程序接口处理收到的PPP报文;向上和网络层协议IP,IPX接口将IP/IPX报文送交IP/IPX协议处理,形成发送网络层报文的控制机制。还研究了PPP协议的安全问题,包括协议的加密和认证机制,确保报文转发过程中的高速和安全性。 The article presents the implementation technology of PPP protocol over high-speed SDH/SONET fiber networks, and applies it to the building of high-speed router.In the implementation architecture, PPP software has a lowed-level interface with hardware drivers,which processes received PPP packets. The higher-level interfaces include those with network layer protocols suck 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 security problem of PPP protocol, including encryption and authentication techniques, which ensures the safety of packets in transit.
