Analysis And Design Of GC College Campus Network Based On IPv6

Universities,as the one of the main technological force in the internet construction,development and promotion,should establish a precedent and lead the internet industry in the deployment and application for the IPv6 technology.GC college need to experience three main stages in the transition from IPv4 to IPv6: a stage of IPv6 application applying in the IPv4 network,a coexistence stage between IPv6 and IPv4,and a stage of IPv4 application applying in the IPv6 network.After analyzing on the protocol and service for IPv6,this paper researched the interim technology,ICMPv6,neighbor discovery protocol,routing protocol,security mechanism,deployment and configuration plan etc.which involved in the transition from IPv4 to IPv6.This paper elaborated the relevant problems on the transition from IPv4 network to IPv6 network,proposed a network strategy transited from IPv4 network to coexistence network between IPv4 and IPv6,solved the key technology problem of routing planning,network configuration and security management about IPv6 application applying in the IPv4 network,the coexistence between IPv6 and IPv4,and the IPv4 application applying in the IPv6 network.This paper configured the dynamic routing,address resolution,network connectivity and service function for the DNS,DHCPv6 and FTP through the network simulation environment based on GNS3 +VPSC.Through the analysis,design and experiment,this paper completed the designing,configuration and simulation verification from IPv4 network transited to coexistence stage between IPv6 and IPv4,and the stage of IPv4 application applying in the IPv6 network,based on GNS3+VPSC simulation experimental environment.The author basically fulfilled the designing requirements of GC College Network.The designing plan can also be modeled to expand the IPv6 network construction and management ideas and improve the technology management level of campus network and teaching level in the colleges.
