Cloud Model of Application of SDN Data to Information Management of College Students' Archives

College student file management system helps teachers quickly find student file information, brings great convenience for teachers to understand students, and also helps the school to master student information, so as to provide students with a more comprehensive development plan. The purpose of this paper is to study the cloud model of college student file information management based on SDN data. Using. NET Web development technology, database technology, cloud platform tools and distributed file system tools, the function design and implementation of the university student file management system are carried out. The specific research work includes the overall design of the system, database design and functional module design and key Function development and implementation, etc. This paper makes full use of the advantages of the SDN global view, designs a DDoS attack detection scheme, and decentralizes the DDoS attack detection function to the data plane. Through experiments, it not only proves that the data security detection mechanism can be implemented on the data plane and obtain performance advantages, more importantly, it is fully utilized. The advantage of the SDN mechanism is to perform DDoS attack detection on the data plane and reduce the overhead of the controller.
