性能一直是网络移动投入实际运营的瓶颈所在,而现有认证机制产生的延时使之雪上加霜.文中为多穴嵌套移动网络的接入路由器Mesh引入一种高效的双向认证机制,基于此提出最优路径选择算法和接入失效快速恢复算法,以提高移动网络的整体性能,尤其是延时的降低.文中,基于固定AAA基础设施和动态可信邻居的安全关联转移被用于减少路由器Mesh的认证延时,其行为评估机制降低了路由器攻击或欺骗对路径评价的影响;基于顶层接入路由器网络前缀的移动路由器转交地址配置被用于消除嵌套接入环境下的多角路由和隧道嵌套问题,而必要时临时隧道和反向路由头可以替代随切换而来的绑定过程以缩短切换延时,最后通过接入路由器评价生成到达Internet的最优路径.定性分析与仿真分析表明,由于异域网络间建立安全关联的高效性,加上行为评估、路径评估和快速切换产生的性能优化作用,文中的安全Mesh在吞吐量、传输延时和切换延时方面较同类方案更加高效.
Performance has always been the bottleneck of the actual operation of network mobile investment, and the delay caused by the existing authentication mechanism makes it worse.This paper proposes an efficient two-way authentication mechanism for access router Mesh with multi-cell nested mobile network, based on which Optimal path selection algorithm and access failure rapid recovery algorithm in order to improve the overall performance of mobile networks, especially the reduction of delay.In this paper, the security association transfer based on fixed AAA infrastructure and dynamic trusted neighbors is used to reduce the router Mesh , The behavior assessment mechanism reduces the impact of router attacks or spoofing on path evaluation. The mobile router forwarding address configuration based on the top access router network prefix is used to eliminate the multi-angle routing and tunneling embedded in the nested access environment Sets up the question, and if necessary, the temporary tunnel and the reverse routing head can replace the binding process with the handover to shorten the handover delay and finally generate the optimal path to the Internet through the access router evaluation.Qualitative analysis and simulation analysis show that, Due to the high efficiency of establishing security associations between foreign networks, coupled with behavioral assessment, path assessment and rapid cut Performance optimization effect produced in the security paper Mesh certain aspects of the transmission delay and handover latency more efficient than competing solutions.
