【摘要】：随着互联网的高速普及以及用户需求的多元化发展,现有互联网所存在的原始设计缺陷愈加突显,诸如移动性差、可扩展性差、安全性差、资源利用率低、能耗大等弊端暴露无遗。如何整体有效的解决上述弊端,实现网络中数据的高效分发、网络资源的动态适配已经是现今迫切需要解决的重要问题之一。 2014年初,国家重点基础研究发展计划(973计划)启动并支持“智慧标识网络理论基础研究”课题。此项目在总结现有互联网运行机制的基础之上,针对现有网络存在的问题,原创性的提出“三层、两域”的智慧标识网络体系架构,实现服务的“资源和位置分离”、网络的“控制和数据分离”及“身份和位置分离”,使得该体系架构能够更智慧、更灵活地支持网络资源动态适配,满足未来网络“高速”、“高效”、“海量”、“泛在”等通信需求,并且更好地支持云计算和云服务。 本论文依托于该项目,对智慧标识网络体系的数据平面进行设计与实现,智慧标识网络体系中数据平面和控制平面不再是紧耦合在路由器上,而是相互分离、协同合作,控制平面组件负责的工作有拓扑的收集与生成、路径计算与决策等,数据平面组件则负责按照控制组件下发的转发规则传输数据,它们相互协作共同完成智慧标识网络中服务资源的获取和传输。 本文首先总结并分析了现有网络所存在的诸多问题,明确了下一代互联网研究的必要性及迫切性。然后根据智慧标识网络体系架构的需求,设计了一种基于标识匹配与转发的数据平面实现方法,其目标是：1)实现数据平面组件与转发平面组件的交互,即接收控制平面下发的控制信息；2)转发平面组件按照控制平面下发的转发规则传送数据请求包；3)转发平面组件维护基于服务标识信息SID和组件标识信息NID转发规则表,完成数据的传送。接下来,本文根据该设计方案进行相应的代码设计和工程实现。最后搭建小型拓扑环境,对数据平面的主要功能进行测试,验证设计方案和是实现方法的正确性。数据转发机制是网络运行的核心内容,数据平面的设计和实现是网络运行的必要基础,本方案的成功实施,为在智慧标识网络平台上进行更深入的研究打下了良好的基础。
[Abstract]:With the rapid popularization of the Internet and the diversified development of users' needs, the original design defects of the existing Internet have become more and more prominent, such as poor mobility, poor scalability, poor security and low utilization of resources. The disadvantages of high energy consumption are exposed. How to solve the above disadvantages effectively and realize the efficient distribution of data in the network, the dynamic adaptation of network resources has become one of the important problems that need to be solved urgently nowadays. At the beginning of 2014, the National key basic Research and Development Program (973 Plan) initiated and supported the subject of "intellectual marking Network theoretical basic Research". This project on the basis of summarizing the existing Internet operation mechanism, aiming at the problems existing in the existing network, original proposed "three layers, two domains" intelligent identification network architecture, to realize the "separation of resources and locations" of the service. The network's "control and data separation" and "identity and location separation" make the architecture smarter and more flexible to support dynamic adaptation of network resources and meet the future network "high-speed", "efficient", "massive". Communication needs such as ubiquitous and better support for cloud computing and cloud services. Based on this project, this paper designs and implements the data plane of intelligent identification network system. The data plane and control plane of intelligent identification network system are no longer tightly coupled on the router, but separate from each other and cooperate with each other. The control plane component is responsible for the collection and generation of topology, path calculation and decision-making, etc. The data plane component is responsible for transmitting data according to the forwarding rules issued by the control component. They cooperate with each other to accomplish the acquisition and transmission of service resources in intelligent identification network. Firstly, this paper summarizes and analyzes many problems existing in the existing network, and clarifies the necessity and urgency of the research on the next generation Internet. Then according to the requirements of intelligent identification network architecture, a data plane implementation method based on identity matching and forwarding is designed. The goal is as follows: 1) the interaction between data plane component and forwarding plane component is realized. Receiving the control information sent under the control plane; 2) the forwarding plane component transmits the data request packet according to the forwarding rule issued under the control plane; 3) the forwarding plane component maintains the forwarding rule table based on the service identification information SID and the component identification information NID, and completes the data transmission. Next, this article carries on the corresponding code design and the engineering realization according to this design scheme. Finally, a small topology environment is built to test the main functions of the data plane to verify the correctness of the design scheme and the implementation method. Data forwarding mechanism is the core of network operation, and the design and implementation of data plane is the necessary foundation for network operation. The successful implementation of this scheme lays a good foundation for further research on intelligent marking network platform.
