[Abstract]:With the rapid development of Internet technology and communication technology, communication network, computer network and cable television network gradually merge, people's work, life, entertainment and so on are closely related to the Internet. The demand of users for network quality of service and information security is more and more high. The Internet Services provider needs to realize better management and maintenance of network through network measurement and analysis, so as to meet the requirements of customers, and at the same time, the research and development of IP network technology. Network security and network behavior research need network measurement. Network measurement, as a basic means to analyze network data and monitor network performance, has become an important topic in network research. However, the accuracy of network measurement results depends on the means and tools of data acquisition. As the basis and premise of network measurement, network data acquisition is the most important part of network measurement engineering. How to design a data acquisition tool with high accuracy, easy management and no influence on the normal operation of the network is the focus of network measurement researchers. Therefore, this paper designs a remote and controllable network data acquisition platform NDCP(Network Data Collecting platform based on Net Magic. The main work and innovations are as follows: firstly, based on the research of network measurement, data acquisition and Net Magic platform, a scheme of remote controllable network data acquisition platform based on Net Magic is proposed. The hardware logical structure and remote control software structure of the platform are designed by using the idea of hardware block and software stratification. The other is to realize a new method of remote control and management of the acquisition platform. The basic framework of software and hardware communication of the platform is designed, the special protocol of remote access control of the data acquisition platform is realized, and the hierarchical structure of the remote control management software of the platform is extended. The basic library functions at the lowest level and the main functions of the application support layer are defined. Third, a new method of hardware design of network data acquisition platform is proposed. Based on the technologies of automatic address acquisition, network address resolution, multi-group storage and search matching, accurate time stamp, etc., the collection platform message recognition and classification, address automatic configuration, search table matching message forwarding, etc. Message sending control and other function modules. Fourthly, the experimental verification environment is built based on the data acquisition platform design, and the function of the key hardware module of the data acquisition platform is verified. The performance of the platform, the consumption of hardware resources and the delay of forwarding message are analyzed. The results of verification and analysis show that the platform runs stably and its function and performance meet the design requirements. The research results have certain theoretical significance and practical value for the innovation and development of network data acquisition technology.
