摘要

针对集中式移动管理协议的不足,提出了分布式移动管理方案。标准DMM是针对扁平结构提出的,它总是从接入层中选择锚点。数值分析表明,动态锚点选择可以提高标准DMM的分组信令性能和传输成本。下一步,提出了一种基于sdn的DMM解决方案,我们称之为SD-DMM,为分层移动网络架构提供动态锚点选择。在SD-DMM中,锚点是由一个虚拟功能动态地为每个移动节点选择的,该虚拟功能作为一个应用程序实现在具有网络全局视图的SDN控制器之上。SD-DMM的主要优点是降低了数据包的传输成本。

Dynamic Anchor Point Selection in Software Defined Distributed Mobility Management
Distributed mobility management (DMM) solution is proposed to address the downsides of centralized mobility management protocols. The standard DMM is proposed for flat architectures and always selects the anchor point from access layer. Numerical analysis is used in this paper to show that dynamic anchor point selection can improve the performance of standard DMM in terms of packet signalling and delivery cost. In next step, an SDN-based DMM solution that we refer to as SD-DMM is presented to provide dynamic anchor point selection for hierarchical mobile network architecture. In SD-DMM, the anchor point is dynamically selected for each mobile node by a virtual function implemented as an application on top of the SDN controller which has a global view of the network. The main advantages of SD-DMM is to decrease packet delivery cost.
