The Research And Implementation Of Cloud Network Experiment Platform

With the rapid development of computer network technology, some resources shortages have come to the current network, such as the IPV4 address shortage. Because of the disadvantages and limitations of current network, it is very important to do some research on the next Internet technology. The research and development of the Internet starts at the Internet experimental platform. The Internet experimental platform is very important for the developing of the Internet, not only the current Internet started at the Internet experimental platform,but also the research of next Internet can not go without the Internet experimental platform. The experimental platform can be divided into two classes:experimental networks, such as the CNGI-CERNET2 Internet2, Geant etc; and Experimental system, such as PlanetLab, NS2 etc.The research of the experimental platform have never stopped at home and abroad, because it is very important for the research of the next Internet, meanwhile it also bring out a visual platform for the simulation of the network attack. With the rapid development of computer network technology, the technology of network attack is also changing, the manner of the network attack getting diverse. At present, it is hardest to prevent the DDOS attack, in order to prevent the DDOS attack it is necessary to study the attack, and to simulate the attack, then find out some corresponding features of the DDOS attack, to provide a reliable evidence for the detection and defense of the network attack. The Large-scale commercial network cannot be used for the simulation experiments of network attack, so a large network experimental platform is needed.The large experimental platform designed and implemented in this paper is called cloud network experimental platform, it has the characteristics of cloud services. Based on the deep research of technology relevant to the cloud network experimental platform, and reference to the current condition of network platform, it brings up a new framework of cloud network experimental platform, and completes the design and implementation of the cloud network experimental platform. A college lab is a private cloud node lab in this paper, it bring out a interconnection solution between private cloud node lab and a solution inside a private cloud. The cloud network experiment platform brings the network equipments which lay at different places together by building tunnel in current Internet, so as to form a large network experiment platform.The cloud network experimental platform provides virtual infrastructure services for users. And it also can provide large attack test which commercial network can not and research services for the next Internet. It proved the cloud network platform has the application properties that can be used for the simulated of the DDOS attack which can not be experimented on the commercial network.
