在未来的异构网络中，随着移动数据流量的激增，需要管理的移动终端数量将大幅增加，由于网络瓶颈和单点故障的产生，目前的集中式移动管理方案可能会遇到可扩展性问题。最近，为了更好地在控制平面和数据平面上分配移动性管理实体，人们提出了一些替代方法，如我们设计的“动态移动性锚定”方案。在本文中，我们比较了集中式和分布式方法，并描述了在这两种方案中使用TCP的仿真环境。所得结果验证了“动动锚”的充分性和设计合理性。他们证实，在未来的网络中，当转向这种分布式移动管理时，我们可能会在切换延迟和全局可扩展性方面期待有趣的好处。
Expecting a significant increase in number of mobile terminals to be managed together with a mobile data traffic boom in future heterogeneous networks, current centralized mobility management schemes may encounter scalability issues due to the creation of network bottlenecks and single point of failures. Recently, alternative approaches have been proposed to better distribute mobility management entities not only in the control plane but also in the data one like the "Dynamic Mobility Anchoring" scheme we designed. In this article we compare centralized and distributed approaches and describe our simulation environment using TCP in both schemes. The obtained results validate the adequacy and design of "Dynamic Mobility Anchoring". They confirm that we may expect interesting benefits in terms of handover latency and global scalability when moving towards such a distributed mobility management in future networks.
