随着移动技术的发展，传统集中式移动管理技术暴露出越来越多问题。解决的办法是通过分布式移动管理技 术，将数据层面和控制层面的功能分布到接入网络中，而不集中在一个网络实体上。目前分布式移动管理技术主要针对移动 IPv6 协议和代理移动IPv6 协议两种主流协议进行改造。每种协议根据其自身特点，可以解决集中式存在的一些问题，提高网 络性能。

】As the development of mobile technique, traditional centralized mobility management exposes more and more problems. One solution is to support distributed mobility management. Instead of deploying on one single network entity, distributed mobility management separates data plane and control plane to access networks. Currently, distributed mobility management is applying to two mainstream protocols: mobile IPv6 protocol and proxy mobile IPv6 protocol. According to the characteristics of its own, each extended protocol can solve problems in centralized scenario and improve network performances.
