Design And Application Of Higher Vocational College Informatization Transformation Scheme

With the rise and application of virtualization,cloud computing,big data,artificial intelligence and other technologies,the Internet has entered the cloud era,and the campus network of higher vocational colleges is also moving towards the smart campus.These new development trends bring new challenges to the existing traditional information network and education and teaching methods of higher vocational colleges.The existing campus information system has many problems: such as network architecture level is not clear,lack of effective regulatory network all the hardware and software resources be abused,low security,WLAN signal coverage and density is not enough,the network bandwidth and the capacity is insufficient,lack of redundancy measures,such as lack of load balancing mechanism,severely restricted the normal education teaching work in higher vocational colleges and the development of informationization,cannot take the wisdom campus for all kinds of business and application.This paper,taking guangzhou modern information engineering vocational college informatization modification,for example,from the campus information network upgrade related technology,requirement analysis,overall design,application and test to discuss several aspects,such as college campus informationization upgrade scheme design and construction problems of higher vocational colleges is expounded informatization reform scheme of the design and implementation process.Firstly,based on the background of guangzhou modern information engineering college,this paper analyzes the existing campus information system infrastructure,existing problems and application systems,and then expounds the necessity of campus information transformation and upgrading and the significance of topic selection.On this basis,the paper briefly introduces the research trends of campus informatization transformation and upgrading at home and abroad and the overall organization of the paper.Secondly,it elaborates on campus informatization technologies such as three-layer switching,VLAN,WLAN,802.1x authentication and network firewall,VRRP and MSTP,as well as network structure flattening,server redundancy and load balancing,virtualization and cloud computing,lightweight AP application and WLAN optimization,micro-service and other campus informatization upgrading and transformation technologies.Thirdly,taking guangzhou current vocational college as an example,aiming at the campus informatization reconstruction and construction project of higher vocational colleges,this paper analyzes the demand from the basic functions,expansibility,management,network security and other aspects of the campus informatization system,and further clarifies the basic principles of the design of the campus informatization upgrading and reconstruction scheme and the goal of the upgrading and reconstruction.Then,the college campus informatization upgrade plan design.Mainly from the core convergence backbone network,intelligent elastic access network,wireless network,integrated wiring system,network security,IPv6 system,microservice-based data center,etc.aspects of campus informatization transformation and upgrading plan design,and through the topological diagram as an auxiliary explanation.Finally,the specific application configuration and test of campus informatization transformation and upgrading are carried out.Mainly from Vlan and IP planning,routing protocol Settings,access security Settings,export firewall Settings,domain name server Settings and other aspects of campus network resources planning and configuration;From the network access,the exit flow,the application system,the network security,the network management,IPv6 and so on several aspects carries on the test to the entire campus informationization upgrade system.
