IPv6 advantages • Increased address space • 2128 = 67 billion billion addresses per cm2 of the planet surface • Hierarchical address architecture • Improved address aggregation • More efficient header architecture • Improved routing efficiency, in some cases • Neighbor discovery and autoconfiguration • Improved operational efficiency • Easier network changes and renumbering • Multiple network prefixes: “make-before-break” • Integrated security, mobility features • QoS • Traffic class • Flow management (flow label) • Peer-to-peer applications
IPv6 Era is coming • IPv6 將取代 IPv4,成為新ㄧ世代的網路協定。 • IPv4的用罄與IPv6 相關的標準已漸趨完整。 • 強化的安全性、更好的QoS與無線技術的應用。 • IPv6帶來無限的商機與應用性 • 因應IPv6 的來臨,相關產品與應用帶來網際網路及週邊產品蓬勃的發展。 • 各先進國家均投入大量人力與經費從事相關研發與推廣(日、韓、中更將其定為國家政策)。

宣佈IPv6 policy • Prime Minister, Yoshiro Mori • I shall boldly address the diverse range of issues we face, including the early realization of e-government, the computerization of school education and the development of systems compatible with the integration of communications and broadcasting, on the basis of discussion in the IT Strategy Council. We shall also aim to provide a telling international contribution to the development of the Internet through research and development of state-of-the-art Internet technologies and active participation in resolving global Internet issues in such areas as IP version 6 (IPv6). • http://www.kantei.go.jp/foreign/souri/mori/2000/0921policy.html
