现有互联网网络体系和机制相对静态、僵化,要从根本上解决现有互联网存在的种种问题,亟待创建新的网络体系、理论及机制。北京交通大学下一代互联网互联设备国家工程实验室提出了以“三层、两域”为典型特征的智慧标识网络体系结构模型。“三层”包括:智慧服务层、资源适配层和网络组件层;“两域”包括:实体域和行为域。在“三层、两域”体系模型的基础上,分别建立了智慧服务层、资源适配层和网络组件层的基本理论,在有效解决网络可扩展性、移动性、安全性等问题的基础上,大幅度提高网络资源利用率,降低网络能耗等,显著提升用户体验。
Existing Internet network systems and mechanisms are relatively static and rigid, and fundamentally solve the problems existing in the Internet. There is an urgent need to create a new network system, theory and mechanism. Beijing Jiaotong University, the next generation of Internet Equipment National Engineering Laboratory proposed to “three layers, two domains ” as the typical characteristics of intelligent identification network architecture model. “Three layers ” includes: intelligent service layer, resource adaptation layer and network component layer; “two domains” includes: entity domain and behavior domain. Based on the model of “three layers and two domains”, we set up the basic theory of intelligent service layer, resource adaptation layer and network component layer respectively, and effectively solve the problems of network scalability, mobility and security Based on the substantial increase in network resource utilization, reduce network energy consumption, significantly enhance the user experience.
