一种基于逆向路由重定向的无缝切换方法

摘要

基于标识分离映射网络环境下的移动性支持特点及需求,针对现有网络移动切换技术所存在的切换时延过大的问题.提出了基于逆向路由重定向的无缝切换方法.该方法由移动性检测、映射信息更新和流量偏转3个部分组成,相比FHMIPv6在时延上可以满足标识分离网络环境下对实时应用的要求,并且切换过程中移动节点参与很少,可节省大量系统无线接入资源.仿真实验表明,切换时廷参数值与分析吻合,可满足各种实时应用需要.%Based on the characteristics and requirements of mobility support under the network environment of identifier mapping separation, aiming at the problem of excessive handoff delay in the existing network mobile switching technologies, a seamless switching method based on reverse route redirection was proposed. The method consists of the mobility detection, mapping information update and flow deflection. Compared with FHMIPv6 on the delay, the method can meet the real-time application requirements in the identifier separation network environment And in the switching process much less mobile nodes are involved, which can save large amounts of wireless access system resources. Simulation results show that the values of handoff delay parameters of this method are consistent with the analysis, thus meeting a variety of real-time application requirements.
