针对移动网络传输过程中出现时滞延迟和数据信息易泄露的问题,文中将MP2P技术与VPN技术相结合,设计了一套面向移动网络信道的MP2P-VPN混合系统.该系统综合设计了终端节点、服务器和证书管理三个方面,建立对应的服务器模块并给出了相应的网络拓扑结构,利用Protocol Buffe工具来达成协议数据的序列化和反序列化工作,确保了数据传输的安全性与稳定性.通过流量监控与传输检验的实验分析,结果表明MP2P-VPN混合系统仅需要一次密钥匹配即可完成证书的检验且节约了网络流量,同时,传输速度使得移动互联通信更加平稳.%Aiming at the problem of delay and delay in data transmission during mobile network transmission,this paper combines MP2P and VPN technology to design a MP2P-VPN hybrid system for mobile network channel.The system integrates terminal node,server and certificate management.The corresponding server module is built and the corresponding network topology is given.Protocol Buffer is used to realize the serialization and deserialization of protocol data.It ensures data transmission security and stability.Through the experiment of traffic monitoring and transmission verification,the results show that the MP2P-VPN hybrid system only needs one key match to complete the certificate verification and save the network traffic.Meanwhile,the transmission speed makes the mobile communication morestable.
