分布式移动管理(DMM
distributed mobility management)是解决移动切换问题的有效方法之一,因此,被认为是能够应用于卫星网络移动性管理的技术。提出了一种基于DMM的软件定义网络(SDN,software defined network)的分布式移动管理方案,来解决卫星网络中的流量重定向问题。与传统DMM应用场景即基于网络或基于终端不同,SDN-DMM方案在SDN控制器中实现位置管理和地址切换。因此,基于SDN的卫星网路分布式移动管理方案相比于传统的方案可以实现分组转发路径优化,并在网络开销和流量管理方面表现出显著的优势。
Distributed mobility management (DMM) was an effective method to solve the mobile address handover.Therefore
it was considered to be a technology that can be applied to satellite network mobility management.A distributed mobile management scheme which based on software definition network (SDN) was proposed to solve the traffic redirection problem in satellite network.Different from the traditional DMM application scenario which was network-based or terminal-based
the SDN-DMM scheme implements location management and address handover in SDN controllers.Therefore
SDN-based satellite network distributed mobile management scheme can realize packet forwarding path optimization compared with traditional scheme
and it shows significant advantages in managementcost and traffic management.
