  26. 27. 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.

  28. 29. Interview with Philip Leung, Director of ITSC
  29. 30. 3.1 Two ways to see internet2 UCAID (University Corporation for Advanced Internet Development) Narrowly speaking Next generation internet (Cernet, Harnet) (more at the appendix) Broadly speaking
  30. 31. 3.2 Features of IPv6 <ul><li>3.2.1 Larger address space </li></ul><ul><li>is the solustion to limited and unfair allocated IPv4 address. </li></ul><ul><li>3.2.2 Stateless auto configuration of hosts </li></ul><ul><li>3.2.3 Multicast (supporting multicasting) </li></ul><ul><li>save redundancy on the internet from the net layer </li></ul><ul><li>3.2.4 Jumbograms </li></ul><ul><li>3.2.5 Faster routing </li></ul><ul><li>faster the transportation </li></ul><ul><li>3.2.6 Network-layer security(IpSEC) </li></ul><ul><li>save efforts to application layer to do the encryption and authentication </li></ul>
  31. 32. Eg of how ipv6 better ipv4 (1) Limited address Allowed in ipv4 Arouse new security problems NAT to solve the problem problems New problems solution
  32. 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. 34. Eg of how ipv6 better ipv4(3) internet with IPv4 already fits most of the need. application layer can fix most of the problem meeting the needs now. No killer application no rush to move from ipv4 to ipv6 so fast Ipv6 better ipv4 in design and function
  34. 35. 3.3 What do Hong Kong react Wait and see HK government reaction See the market No immediate Profitable application
  35. 36. 3.4 HARNET and CERNET <ul><li>3.4.1 HARNET </li></ul><ul><li>HARNET is Hong Kong Academic and Research Network </li></ul><ul><li>Managed by Joint Universities Computer Centre (JUCC) </li></ul><ul><li>Supports the eight Universities funded by the University Grants Committee (UGC) </li></ul><ul><li>Also supports some non-profit organizations in Hong Kong </li></ul>

UMBRELLA MODEL ANALYSIS <ul><li>HARDWARE </li></ul><ul><li>Enabling: </li></ul><ul><li>Optical Fiber </li></ul><ul><li>Updated Router refers to the router supporting IPV6 or the one supporting IPV4 and IPV6 simultaneously. </li></ul><ul><li>Limiting: </li></ul><ul><li>Bandwidth Limitation </li></ul><ul><li>When the adoption of I2 expands to the business field, with the dramatic increment of the users, unless there is a technology innovation, the speed of I2 cannot be maintained at a satisfactory level any more. </li></ul>
  43. 45. UMBRELLA MODEL ANALYSIS <ul><li>SOFTWARE </li></ul><ul><li>Motivating: </li></ul><ul><li>IPV6 1. Larger address space </li></ul><ul><li>2. Better capability of QoS 3. Enhanced security </li></ul><ul><li>High Bandwidth 2.5Gbit/s </li></ul><ul><li>Steady Bandwidth </li></ul><ul><li>Inhibiting: </li></ul><ul><li>Network Security 1. A stricter or another totally different definition of network security in the future </li></ul><ul><li>2. DOS Attack </li></ul><ul><li>Incompatibility with IPv4 </li></ul><ul><li>1. Operation System 2. Web Browser </li></ul><ul><li>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 </li></ul><ul><li>提出了集成服務模型 (Integrated-Service Model) 和有差別的服務模型( Differentiated-Service Model ) </li></ul><ul><li>開發了 RSVP 、 RTP/RTCP 等協議 </li></ul><ul><li>制定了業務流的分類方法( Cos ) </li></ul><ul><li>實現了各種佇列技術( PQ 、 WFQ 、 LLQ 等)和包丟棄策略( WRED ) </li></ul><ul><li>開發了流量整形( Traffic Shaping )技術 </li></ul><ul><li>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. </li></ul>
