Research And Implementation Of Data Storage For Network Test Platform

The innovation speed of Internet and technology is very quickly now, how to popularize these new technology created by the innovation is an inevitable problem now. These innovative experiments need a network environment which could be close to the real network. But the existing network base frame is very difficult to be changed, and the technology deployment is limited by the existing network. So network researcher demand for a real or close to the real Internet environment is becoming more and more intense. So the network test bed arises at the historic moment. It provides a platform with a real network environment which can test the development of new technology for network researcher.At present, in the existing network test bed, American PlanetLab test bed, the FIRE test bed programs, as well as the Japanese CoreLab is the most mainstream test bed. Although the test bed has made great achievements so far, because of their bottom are still using the traditional network equipment, the whole network structure is still rigid. This also seriously limits the range of network technology innovation. And on this basis, the test bed with OpenFlow bottom structure can go further than before. It broke the traditional rigid closed network architecture, and realized the separation of data control and data transmission. It can also make the new network technology innovation transfer to the development of new control plane for applications, and the general network interconnection equipment for data plane makes the test bed become universal, which is conducive to the spread of a variety of experiments.The content of this article is based on the contents of the OpenFlow test bed, using Openstack structure to deploy and manage the resource of the test bed. The main focus of the research is to improve the original Openstack Swift storage mechanism. Starting from Swift’s core components, Ring, to improve its mapping mechanism and distribution algorithm, and add a Coping mechanism for the poor network or equipment state to the frequent failure of the storage, improving the security of the stored data.
