Study on Availability and Security of DHCP System In Campus Network

Abstract —To improve the availability and the security of DHCP system in campus network, the DHCP protocol and the typical fault cases are analyzed, and the three deploy strategies are developed to help the DHCP deployment. Firstly, planning the network addresses properly to prevent the confliction; Secondly, managing the server uniformly with the relay devices; Lastly, implementing the authentication to shield the illegal server. The experiment results show that the strategies are effective for enhancing the availability and security of the DHCP system
