Research on Evolution from IPv4 to IPv6 in Power Information Network
Because of the urgent needs of IP addresses in power information network,the evolution from IPv4 to IPv6 has become an inevitable trend.With the actual demand of power information network,this paper proposes a technical solution for the smooth evolution from IPv4 to IPv6,which takes mainstream transformation technology and real evolution scenario into account and bases on the principles including utmostly protecting existing investments,smooth transition and seamless migration.The proposed solution divides the transitional process into three stages and puts forward the corresponding technological method of transition and transformation for each stage by considering its real evolution scenario.It is a good attempt for the smooth transition from IPv4 to IPv6 in power information network.
