面向多维统一标识体系的标识解析映射机制

Identity Resolution and Mapping Mechanism for Multidimensional Unified Identity Architecture

传统互联网标识命名及其解析映射机制存在缺陷,难以满足当今互联网应用智能化、多元化、一体化的趋势。该文提出了一种面向多维统一标识体系的标识解析映射机制,为设备、内容、服务、特定组等多种网络主体提供了基于多维属性的通信服务。该机制围绕多维统一标识体系框架与运行机理,采用包含服务层和网络层的双层解析映射框架,设计了多维统一标识映射报文和标识解析映射双层工作流程,完成了多维统一标识映射注册、查询的请求和响应,从而实现了资源搜索、服务定位、网络感知的功能。搭建了基于可编程数据平面的多维统一标识解析映射原型系统,并对标识解析映射机制的功能和性能进行实验评估。结果表明,在高并发高移动场景下该机制能够支持面向多维统一标识体系的高效解析映射。

Traditional Internet identity naming and its mapping mechanism have defects,which are difficult to meet the trend of intelligent,diversified and integrated Internet applications.In order to provide multidimensional attribute-based communication services to multiple network principals such as devices,contents,services,and specific groups,an identity resolution and mapping mechanism for multidimensional unified identity architecture is proposed.Around the framework and operation mechanism of the multidimensional unified identity architecture,a two-layer resolution mapping framework with service and network layer is designed into the mechanism.A message which is used to deliver mapping request and response information and a workflow that handle two-layer resolution mapping process are designed to achieve resource search,service location and network awareness.A prototype system of multidimensional unified identity resolution and mapping based on programmable data planes is built,and the functional and performance evaluation of the identity resolution and mapping mechanism are evaluated.The results show that the mechanism can support efficient resolution mapping for multidimensional unified identity architecture under high concurrency and high mobility scenarios.
