  1. Internet for Everything IPv6 is the answer! IPv6 workshopTWING 2003 謝佳男 chianan@twnic.net.tw TWNIC

  2. Speaker’s Short bio • Chia-Nan Hsieh (謝佳男) • chianan@twnic.net.tw • M.S. in Telecom. Engr. (UMCP) • Current position: • Engineer, TWNIC • Product Manager, National IPv6 Development & Deployment Program • Co-Chair, APNIC NIR SIG • Experience: • Network Engineer, University of Maryland

  3. WHY IPv6?

  4. Ethernet 30 週年紀念 Ethernet and TCP/IP were both invented in Palo Alto during the summer of 1973, the CSMA/CD LAN Ethernet at Xerox Parc and TCP/IP WAN Internet at Stanford.  Ethernet has evolved from 2.94Mbps over shared coaxial cable, to 100Mbps over switched twisted pairs, to 100Gbps over fibers, to 11Mbps over radio at 2.4GHz, and beyond.  Meanwhile, TCP/IP has evolved to IPv4, where it has been sitting for too long.  Time for IPv6! ~ Bob Metcalfe ~

  5. Internet for Everything • No longer just “Internet for Everyone” • “Peer to peer” between any pair of devices, not just people on computers • appliances, automobiles, buildings, cameras, control units, embedded systems, home networks, medical devices, mobile devices, monitors, output devices, phones, robots, sensors, switches, VPNs • No more NAT (“fog on the Internet”) • Eventually, every device will be connected to the Internet • and every device will need an address Internet for Everything! ~ Paul Wilson ~ Director General of APNIC

  6. IP on Everything

  9. 日本 IPv6 應用實例 IPv6 計程車 (日本) . 提供乘客當地生活資訊 . 提供乘客駕駛健康狀況 . 依踩剎車的頻率, 搜集交通擁塞狀況 . 依雨刷頻率,搜集天候資訊

  10. IPv4的問題 • IP 位址數量不足，影響網路應用的發展 • NAT 有其限制 • 造成數位落差 • 路由表日益增大，影響路由效率 • 設定及管理不易 (Auto-configuration) • 缺乏 IP 層的安全性需求 (IPSEC) • 缺乏服務品質的支援 (QoS) • ….

  11. IP 位址數量消耗情形 • TCP/IP 於 1973年發明，IPv4 於1981 年成為 RFC (791) • 1985, 使用 1/16 • 1990, 使用 1/8 • 1995, 使用 1/3 • 2000, 使用 1/2 • 2003, 使用 2/3 • IPv4 位址數量 • 理論值: 232=4,294,967,296 (42億) • 實際值: 2.5 億 (RFC3194, 2001) 2008

  12. 40 2002 Millions 2001 2000 32 1999 1998 1997 1996 24 Pre-1996 16 8 0 JP CN KR AU TW HK IN TH MY SG Other 亞太地區各國 IP 位址成長量

  13. 位址數量面臨不足 • IP 位址是網際網路的公用資源 • 2003/3 IANA 剩下約 31% /8 可用(75-80個 /8) • 2002/9 時還有 35% (半年用掉 4 %) • 中國 12 億人口 • 每人一個 IP， 需 72 個 /8 • 印度 10 億人口..

  14. 數位落差 - 網際網路資源分配不均

  15. NAT的缺點 • 全球1000大公司有70%使用NAT • 但是: • NAT 破壞全球位址唯一性 • NAT 破壞點對點的透明性 (無法確認真實身份) • NAT 使得 QoS、Security 功能及協定失效 • NAT 使得某些應用軟體功能無法使用(content sharing, distributed computing, on-line gaming…) • NAT 提高網路隱藏性的成本 (e.g. NAT設備費用、位址轉換時間…)

  16. 路由表日益增大 * BGP Statistics focusing on the Asia Pacific Region * Routing Table Report 04:00 +10GMT Mon 02 Jun, 2003 Analysis Summary ---------------- BGP routing table entries examined: 125504 Prefixes after maximum aggregation: 78740 Unique aggregates announced to Internet: 59216 Total ASes present in the Internet Routing Table: 15264 Origin-only ASes present in the Internet Routing Table: 13228 Origin ASes announcing only one prefix: 5992 Transit ASes present in the Internet Routing Table: 2036 Source: bgp-stats@lists.apnic.net

  17. 路由表日益增大 網路泡沫化 .com熱潮 採用CIDR Source: Apnic

  18. IPv6 的優點 • 增大的位址空間 • 128 位元 • (2128 = 340,282,366,920,938,463,463,374,607,431,768,211,456) • 足以分配給地球上每一粒沙 • 階層性位址架構 • 增進位址聚集，減低路由表的大小 • 高效能的標頭(header)架構 • 提高封包轉送效能 • 自動設定(auto-configuration) 機制 • 內建安全性支援 • 較佳的QoS支援

  19. IPv4與IPv6的比較

  20. Prime Minister of Japan • IPv6 Transition by 2005 • 2001年經費達 80 億日元 • Sony • “In 2005, all Sony products will be IPv6-enabled” • 美國國防部 • 2003年10月起所採購之網路設備，也必需具備IPv6功能。 • 韓國 • 政府於 2001 年正式宣示推動 IPv6 • 839億韓元(USD$83M)預算 • EU Commission • 建議各國政府及工業界儘早投入IPv6 • 總研究經費達1.56億歐元 

  21. IPv6 in Taiwan

  22. TW IPv6 Promotion Bodies • NICI IPv6 Steering Committee • Established by NICI in Nov.2001 (NICI: National Information and Communications Initiative Committee ) • Proposed “National IPv6 Development and Deployment Program”, now a part of e-Taiwan project • IPv6 Forum Taiwan • Established by TWNIC and ITRI in Apr.2002 • Aims to improve market/industry and user awareness of IPv6 • “IPv6 Industrial R&D Alliance” • Accton, D-Link, ASKEY, ADMTek, Z-Com, Loop..

  23. IPv6 Forum Taiwan • IPv6 Forum Taiwan Journal (Bi-annual) • Taiwan IPv6 Portal Site • www.ipv6.org.tw • News, Articles, Discussion Boards, References…etc. • International Cooperation • Coop Meetings • With JP in 2002, 2003 • With KR in 2003 (July.5.2003) • Agreement and MoU • IPv6 Promotion Council (signed) • Eurov6 Project (signed) • IPv6 Forum Korea (expected)

  24. IPv6 in e-Taiwan Project • e-Taiwan Project • 36 billion NTD (about 1 billion USD) allocated • Holds the key to the success of “Challenge 2008: the 6-year National Development Plan” • http://www.nici.nat.gov.tw • 5 integral parts • e-Infrastructure “Broadband networks will be fully installed with implementation of IPv6 and wireless LAN environment” • Ez Life • e-Industry • e-Government • e-Transportation

  25. IPv6 Deployment & Development Program • A 5-year project (2003-2007) • Proposed by “NICI IPv6 Steering Committee” • Missions: • To help public Internet infrastructure upgrading to IPv6 • To integrate existing IPv6 resources and efforts from the government, industry, and research institutes • To enhance competitiveness of local industry • USD1,700,000 allocated for 2003 • www.proj.ipv6.org.tw

  26. IPv6 Address Allocations Status Source: APNIC, Jun 2003 Government began to push

  27. IPv6 的挑戰 • Security • No Universally Trusted PKI • IPSEC implementation is complex • QoS • Communication between Qos Internet & non-QoS Internet • Standards • Need more work on Mobile IP, Multicast.. • ROI (Return of Investment) • Not able to generate revenue at present • Unexpected social impact • …
