【摘要】：随着互联网的迅速普及和爆炸性发展,网络资源利用率低、网络能耗高等弊端逐步显现。现有互联网相对“静态”和“僵化”的网络体系和机制,导致网络新技术和新理念的部署困难。现有互联网具有“三重绑定”的特征,即：服务资源和服务位置的绑定、网络控制和数据转发的绑定、用户身份和用户位置的绑定。这些原始设计的特征,是导致现有互联网在可扩展性、移动性、安全性等方面存在问题的根本原因。 2013年,智慧标识网络理论体系研究团队在国家973项目“一体化可信网络与普适服务体系基础研究”的研究基础上,提出了“三层”、“两域”的网络总体架构模型。“三层”即：智慧服务层、资源适配层和网络组件层。“两域”分别指“实体域”和“行为域”。而智慧标识网络控制平面是独立于网络转发层面的网络资源适配和决策下发的核心。本文以智慧标识网络理论体系为背景,提出了智慧标识网络原型系统控制平面的设计方案和实现方法,体现了智慧标识网络理论体系的基本思想,并通过测试验证方案的有效性,为智慧标识网络理论体系的发展奠定工程基础。本文首先总结了现有互联网所存在的诸多问题,详细分析了目前下一代互联网研究领域的前沿思想和技术。然后以智慧标识网络理论体系为基础,结合现有的控制和转发分离的技术,提出智慧标识网络控制平面的设计方案。基于该设计方案,实现了控制平面的以下功能：1)数据平面网络资源信息和状态在控制平面的收集和处理；2)基于服务请求和网络状态的资源适配；3)控制平面决策消息的下发。最后,在基础的网络拓扑环境下,通过完成一次服务获取验证了本文所述设计和实现方案的有效性。
[Abstract]:With the rapid popularization and explosive development of the Internet, the disadvantages of low utilization of network resources and high energy consumption of network gradually appear. The existing Internet is relatively "static" and "rigid" network system and mechanism, resulting in the network of new technologies and new ideas difficult to deploy. The existing Internet has the characteristics of "triple binding", that is, the binding of service resources and service location, the binding of network control and data forwarding, and the binding of user identity and user location. These features of the original design are the root cause of the scalability, mobility, and security problems of the existing Internet. On the basis of the national 973 project "Integrated trusted Network and basic Research of Universal Service system", the research team of intelligent identification network theory system puts forward the overall network architecture model of "three layers" and "two domains". Three layers are: intelligent service layer, resource adaptation layer and network component layer. "two domains" refer to "entity domain" and "behavior domain" respectively. The intelligent identification network control plane is the core of network resource adaptation and decision making independent of network forwarding. In this paper, the design scheme and implementation method of the control plane of the intelligent marking network prototype system are put forward based on the intelligent label network theory system, which embodies the basic idea of the intelligent label network theory system. The validity of the scheme is verified by testing, which lays the engineering foundation for the development of intelligent identification network theory system. This paper first summarizes the problems existing in the Internet and analyzes in detail the advanced ideas and technologies in the next generation Internet research field. Then, based on the intelligent label network theory system, combined with the existing technology of separation of control and forwarding, the design scheme of intelligent marking network control plane is put forward. Based on the design scheme, the following functions of the control plane are realized: 1) the collection and processing of the data plane network resource information and state in the control plane, 2) the resource adaptation based on the service request and the network state; 3) controlling the sending of decision message in plane. Finally, under the basic network topology environment, the effectiveness of the design and implementation scheme is verified by completing a service acquisition.
