摘　　要：标识网络的提出解决了传统TCP/IP网络中IP地址“二义性”带来的移动性问题,然而标识网络的颠覆式创新在现网中部署存在困难。随着协议无关的可编程平台技术不断发展,为解决标识网络部署困难带来可能,为标识网络的大规模推广带来便利条件。该文提出一种基于可编程平台的标识网络移动性管理机制,结合可编程平台数据与控制分离的特点,在数据平面设计一套报文处理与转发逻辑实现数据报的解析与转发,在控制平面设计包含四个模块的控制系统实现设备身份认证与映射注册、跨接入域通信的映射查询、移动终端跨接入域移动切换等网络功能。基于可编程平台搭建了标识网络原型实验系统,对基于可编程平台的标识网络移动性管理机制的功能和性能进行实验测试评估。结果表明,该机制能够支持标识分离映射、标识发布与查询、设备移动切换等功能,性能满足大部分实时应用需求。The proposal of Smart Identifier Network solves the mobility problem caused by the"ambiguity"of IP address in traditional TCP/IP network,but the subversive innovation of Smart Identifier Network is difficult to deploy in the existing network.With the continuous development of protocol-independent programmable data plane technology,it is possible to solve the difficulties of Smart Identifier Network deployment and bring convenient conditions for the large-scale promotion of Smart Identifier Network.We propose a Smart Identifier Network mobility management mechanism based on programmable data plane,which combines the characteristics of data and control separation of programmable data plane,designs a set of message processing and forwarding logic in the data plane to realize the parsing and forwarding of packet,and realizes network functions such as device identity authentication and mapping registration,mapping query of cross access domain communication,and cross access domain mobile switching of mobile terminals in the control plane design with four modules.In this paper,a prototype experimental system of Smart Identifier Network is built based on the programmable data plane,and the functions and performance of the identity network mobility management mechanism based on the programmable date platform are experimentally tested and evaluated.The results show that the mechanism can support functions such as identity separation mapping,identity publishing and query,and device mobile switching access,and the performance meets the requirements of most real-time applications.
