[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.
