Design And Implementation Of Campus Wireless Network Based On 802.1X Protocol

As an indispensable auxiliary teaching and research infrastructure,the campus wireless network can make up for the weakness such as lack of a wired network,the high cost of construction,less information and poor portability,and has become the main way for university teachers and students to get access to network information resources.Therefore,the construction of a unified campus network can undoubtedly meet the growing demand for network access of teachers and students and make the school teaching and research work more convenient and efficient.However,the security problem of campus wireless network is becoming more and more prominent with the increasing of the campus network scale and the openness.This paper discusses the specific design and implementation process of a campus wireless network platform and construction scheme based on 802.1X authentication in a university.The system is tested and its feasibility is verified.This paper first analyzes the RADIUS server architecture which implements the 802.1X authentication system and gives the basic structure of RADIUS protocol,the running process and the implementation principle of AAA service.Secondly,the paper discusses the DHCP protocol and the 802.1X authentication system and compares several mainstream network authentication technologies and expounds the advantages of 802.1X authentication in the campus network environment.Then,the paper gives the overall design scheme of campus wireless network and the specific planning of campus network framework,and respectively plans a campus wireless network module and wireless network topology without changing the cable network on the basis of the frame.The paper also schemes specific design ideas based on 802.1X wireless network authentication,gives reasonable plans for the security mechanism of the campus wireless network,and provides solutions to the design of operation optimization system for 802.1X certification.Then,it discusses the implementation process of the scheme,complete wireless controller,core switches,aggregation switches,access switches and other specific configuration and rapid query system and quick connect system realization.Finally,the well-designed campus wireless network system is implemented and tested,and the testing results show that the campus wireless network is functioning normally.
