】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.
