What is the next generation Internet we neededInternet have been an important infrastructure today and still deploy very fastMajor characteristics of next generation Internet:Large scale network: IPv6 addressEnd to end high performanceSecure and trustworthy networkQoS control networkMobility There is not unify definition for next generation Internet but IPv6 should be an important part of NGI

Why is IPv6 needed?Much larger address spaceIPv6 Addresses: 3.4X1038Trustworthy network: real IP address accessImproved routing Route aggregation reduces the size of routing tablesSimplified header reduces router processing loads Enhanced security and QoS Mandatory IPsec support all fully IPv6 compliant devicesImproved support for mobile IP and mobile computing devicesIP is everywhereData, Voice, Audio and Video integration is a RealityRegional Registries apply a strict allocation control
