摘　　要：考虑通信传输受多重因素影响,为解决加密传输状态下电子通信的延迟问题,研究基于IPSEC安全加密的电子通信低时延传输方法。构建多跳网状电子通信网络模型,通过复制机和逐跳重传机制提高路由容错和数据传输的稳定性,并减少节点能耗;考虑链路度量及传输成功率的影响,确定下一跳传输节点集合,分析IPSEC安全加密对电子通信传输时延的影响;在资源高度占用的情况下,解决传输时延和吞吐量分配问题,通过建立两跳有损链路模型,构建有损、多跳和再编码等多个应用场景,逐步剔除各个层级编码分组和头部编码;考虑偶遇条件概率机制,调整链路选择完成分组传输,实现低时延传输。经实验证明所提方法传输成功率高,具备较好的传输条件,传输时延低。In order to solve the problem of electronic communication delay in encrypted transmission,this paper presented a low-delay transmission method of electronic communication based on IPSEC security encryption.At first,a multi-hop electronic communication network model was built.Then we used the duplicator and hop-by-hop retransmission mechanism to improve the routing fault tolerance and data transmission stability,so as to reduce the energy consumption of nodes.Afer considering the impact of link metrics and transmission success rate,we determined the transmission node set in the next hop.And then,we analyzed the impact of IPSEC security encryption on electronic communication transmission delay.Moreover,we solved the problem of transmission delay and throughput allocation in the case of high resource consumption.Furthermore,we constructed a two-hop lossy link model and used it to construct lossy,multi-hop and recoding scenarios,thus gradually eliminating the coding groups and header codes at all levels.According to the conditional probability mechanism,we adjusted the link selection and thus completed the packet transmission.Finally,we achieved low-delay transmission.Experiment results prove that the proposed method has high success rate,good transmission conditions and low delay.
