提出了一种基于树状结构的在移动IPv6网络中实现Anycast服务模型,该模型采用了Unicast与Multicast技术。在该模型中,每个组成员只通过一个归属地址(无需转交地址)就可以完成与客户端的数据通信;组成员移动到外区时,无需向归属代理注册,也无需在归属代理与转交地址之间建立隧道,针对路由优化情况,Anycast组成员也无需向客户端发送转交地址的绑定消息;根据网络的拥挤情况动态地选择最优组成员,解决了在移动IPv6网络中IPSec很难实现的问题。在IPv6模拟环境下,实验数据证明了该模型的实用性、有效性以及高效性。
A Anycast service model based on tree structure in Mobile IPv6 network is proposed. The model uses Unicast and Multicast technologies. In this model, each group member can complete the data communication with the client through only one home address (no need to transfer address). When a group member moves to the outside area, there is no need to register with the home agent or the home agent and the care-of address For the sake of route optimization, members of Anycast group do not need to send binding messages to clients to forward addresses. According to the congestion of network, the optimal group members are dynamically selected to solve the problem that IPSec is difficult to implement in mobile IPv6 networks The problem. In the IPv6 simulation environment, experimental data demonstrate the practicality, effectiveness and efficiency of the model.
