2. Slide 3: Let’s start imagine... Way, way cool.
3. Slide 4: The Technophobe & the Madman ~the first internet 2 Distributed Musical~ -a 40-minute performance was seen simultaneously at Rensselaer and at New York University (February 20,2001) -the first Internet2-distributed musical, combining music, video, and interactivity using artists performing collaboratively at both locations. -High-bandwidth versions and a video of the entire musical can be viewed at.
4. Slide 5: The Technophobe & the Madman Rensselaer Internet2 connection New York Polytechnic University Institute 6 video and 12 audio channels 20 mbps Simultaneous performance
5. Slide 6: 1.Background 1.1 What is Internet 2 1.1.1 Setup of Internet 2 • a group of 36 scientists met in Chicago to discuss ways of developing and implementing a new Internet in 1996, which they named Internet2. • a not-for-profit advanced networking consortium • led by the research and education community in US • the goal is to “create the next-generation Internet”, making it faster and more stable.
6. Slide 7: 1.1 What is Internet 2 Made up of 70 leading corporations More than 200 U.S. universities 45 government agencies, laboratories and other institutions over 50 international partner organizations
7. Slide 8: 1.1 What is Internet 2 1.1.2 Definition • Internet2 is a consortium of universities, technology companies and government agencies working to develop and deploy advanced network applications and technologies in order to accelerate the creation of a next-generation Internet.
8. Slide 9: 1.1 What is Internet 2 1.1.3 Mission & Goals Internet2 Mission • Develop and deploy advanced network applications and technologies, accelerating the creation of tomorrow’s Internet. Internet2 Goals • Enable new generation of applications • Re-create leading edge R&E network capability • Transfer technology and experience to the global production Internet
9. Slide 10: 1.1 What is Internet 2 1.1.4 Abilene -a dedicated backbone network for the Internet 2 community. -a proving ground for high- bandwidth technologies.(up to 10 Gbps) -a dual-stack IPv4/IPv6 network. -designed to provide optimal performance to both IPv4 and IPv6 packets.
10. Slide 11: 1.1 What is Internet 2 Abilene The Indiana University Abilene Network Operations Center Weathermap shows the current status of the Abilene network at 10Gbps.
11. Slide 12: 1.1 What is Internet 2 1.1.5 Why we need it -Problems of today's Internet • The Internet is sometimes seen as a victim of its own success - security issues - QoS(quanity of service) - bandwidith(eg:slow downloads) - addressing(IPv4) - the exploding need for URLs - spam,etc.
12. Slide 13: 1.1.5 Why we need it Potential of Internet 2 Technology commerce and business research healthcare And and education science community arts and humanities and beyond The Internet2 community pioneers the use of advanced network applications and technologies, from their academic inception through their evolution to the commercial Internet.
13. Slide 14: 1.1.5 Why we need it? Relationship of internet & internet2 • not a separate physical network • Internet2 users can only contact other Internet2 users. • Internet2 have not been open to the public. • BUT internet2 will not replace the Internet • the technologies developed in Internet2 will gradually be transferred to the original internet, making it faster and more stable. • The goal of Internet2 is to create the next-generation Internet

26. Slide 27: 2.4 Collaborative Tele-immersive Virtual Reality In teleimmersion, participants are not looking at a scale model of a car design; they are standing inside the engine block. They can then change parameters on a supercomputing simulation of the engine block and collectively study the impact of those changes. Long-distance Car Design Case 45Mbps Bibby in MIT Sunson in UCLA
27. Slide 28: 3. Interview study and global NGI 3.1 Two ways to see internet2 3.2 Features of IPv6 3.3 What do Hong Kong react 3.4 Harnet and Cernet 3.5 appendix
28. Slide 29: Interview with Philip Leung, Director of ITSC
29. Slide 30: 3.1 Two ways to see internet2 Narrowly speaking Broadly speaking Next generation UCAID internet (Cernet, Harnet) (University Corporation for (more at the appendix) Advanced Internet Development)
30. Slide 31: 3.2 Features of IPv6 • 3.2.1 Larger address space • is the solustion to limited and unfair allocated IPv4 address. • 3.2.2 Stateless auto configuration of hosts • 3.2.3 Multicast (supporting multicasting) • save redundancy on the internet from the net layer • 3.2.4 Jumbograms • 3.2.5 Faster routing • faster the transportation • 3.2.6 Network-layer security(IpSEC) • save efforts to application layer to do the encryption and authentication
31. Slide 32: Eg of how ipv6 better ipv4 (1) problems Limited address solution Allowed in ipv4 NAT to solve the problem New problems Arouse new security problems
32. Slide 33: Eg of how ipv6 better ipv4(2) OSI model Shortages of ipv4 can be solved on application levels ipv6 can probably perform on network layer
33. Slide 34: Eg of how ipv6 better ipv4(3) internet with IPv4 Ipv6 better ipv4 already fits most of the need. in design and function application layer can fix most of the problem meeting the needs now. no rush to move from No killer application ipv4 to ipv6 so fast
34. Slide 35: 3.3 What do Hong Kong react Wait and see HK government reaction No immediate See the market Profitable application

42. Slide 44: 4. UMBRELLA MODEL ANALYSIS
43. Slide 45: • Incompatibility with IPv4 1. Operation System 2. Web Browser QOS 可以讓不同的資源獲得不同的等級和服務品質，保證資訊安全 準時地抵達收件人．需要說明的是， IPv4 也 可以提供 QOS 服務，為此技術人員先後 UMBRELLA MODEL ANALYSIS • 提出了集成服務模型 (Integrated-Service Model) 和有差別的服務模型（ Differentiated-Service Model ） • 開發了 RSVP 、 RTP/RTCP 等協議 • 制定了業務流的分類方法（ Cos ） • 實現了各種佇列技術（ PQ 、 WFQ 、 LLQ 等）和包丟棄策略（ WRED ） • 開發了流量整形（ Traffic Shaping ）技術 但這些協定和技術提高了網路規劃和建設的成本、複雜性，並且無法實現真正的端到端的服務品質保證． IPv6 可 以有效地解決這一問題． IPv6 報頭中的 8 比特的通信類別（ Traffic Class ）欄位可以支援多達 64 種業務流，此外 IPv6 增加了 Flow Label 欄位，可以對多媒體資料流程提供良好的標識和支援，這樣路由器可以對流中的資料包進 行高效處理和分類服務．

Slide 46: CISCO & JUNIPER CHINA JAPAN UMBRELLA MODEL ANALYSIS 而思科、 Juniper 等國際大廠借助 IPv4 形成的研發規模 2004 年上半年，華為的路由器產品開始全部支援 IPv6 ； 目前，從世界範圍來看，日本在 IPv6 技術和產品研發上 和市場環境，在市場推廣和產品研發上佔有更多優勢。他 中興在做系統設備的同時，也加強了 IPv6 晶片的研發； 走在前列，其中，日立、富士通、 NEC 的 IPv6 設備投放 們不僅在路由器中增加了支持 IPv6 功能，思科還在蘇格 大唐電信為中國軍隊提供了多款高保密級別的 IPv6 路由 市場較早，在日本和歐洲佔有比較高的市場份額。日立公 蘭專門建立了 IPv6 研發中心． 器；佳訊飛鴻則主打彙聚層 IPv6 路由器市場。 司 2001 年推出的世界最早的硬體支援的 IPv6 千兆級路由 器 GR2000 系列目前在全球銷售超過萬台，其中作為 IPv6 路由器使用的超過 50% 。
45. Slide 47: U.S. 1996 年 10 月 6 日 , 克林頓總統宣佈聯邦政府將參與 Internet2 計畫 , 參與此項計畫的聯邦機構有 : 國家科學基金 會、能源部、國家宇航局、國防部的高級研究計畫署以及國家健康研究所 , 另外環境保護署和商業部也參與了此項 UMBRELLA MODEL ANALYSIS 計畫。在 1998 年的財政預算中 , 聯邦政府將拿出 1 億美元的資金支援 Internet2 工程。 CHINA 1998 年 4 月，建立中國第一個 IPv6 試驗網。 CERNET 採用隧道技術組建了我國第一個連接國內八大城市的 IPv6 試驗床，獲得中國第一批 IPv6 地址。 8 月，承擔國家 863 計畫課題“ IPv6 示範系統”。 1999 年 5 月， CERNET 正式接入國際提供 IPv6 學術性服務的網路 6REN 。 11 月，國家自然基金委員會正式立項 ，資助“中國高速互聯研究試驗網路” (NSFCNET) 。 2000 年 3 月，正式與國際下一代互聯網簽署互聯協定。同年，在北京清華大學建成中國第一個下一代互聯網交換 中心。 10 月， CERNET 首先在中國提供 IPv6 位址分配服務。 2001 年 3 月，首次實現了與國際下一代互聯網路 Internet2 的互聯。７月，＂中國高速互聯研究試驗網路＂通過國 家自然基金委項目鑒定和驗收． 2002 年 1 月，國家啟動“下一代互聯網中日 IPv6 合作項目”。 5 月，清華大學等單位承擔國家“ 863” 重點課題 “新一代互聯網技術綜合實驗環境”。 8 月，國家發改委正式成立“下一代互聯網發展戰略研究專家委員會”，正 式啟動重大問題軟科學研究專案“下一代互聯網發展戰略研究”。全體專家共同努力于 2002 年 10 月完成了《下一 代互聯網發展戰略研究報告》。 2003 年 8 月，國務院批復同意國家發展改革委等八部委“關於推動我國下一代互聯網發展有關工作的請示”，正 式啟動“中國下一代互聯網示範工程 CNGI” 。 12 月，科技部批准 2003 年國家重大基礎性研究 973 計畫專案“新 一代互聯網體系結構理論研究”。
