  2. NetLMM Overview 1.Introduction 1.1-Mobility Management 1.2-Mobile IPv6 Problem 2.Related Work 2.1-MIPv6 and HMIPv6 2.2-Summary 3.NetLMM Approach 3.1-Overview 3.2-Message flow 3.3-Handoff ’s Message Flow 3.4-Compare To Mobile IPv6 4.Data Flow

  3. IntroductionMobility Management • Mobility management • 找到行動用戶目前所在的位置 • 傳送和接受資料封包 • 保持行動用戶的連接 • 如同行動用戶不斷地移動改變他所附著的基地台 • Mobile IPv6 (MIPv6) • Ipv6是個眾所周知的成熟標準，IPv6的標準中內建支援行動IP(Mobile IP).的功能，使得在IPv6的環境下要行動上網更加方便。 • 能夠解決在mobile ipv4下所碰到的許多問題)

  4. IntroductionMobile IPv6 Problem • ‧仍然顯示出一些問題例如換手延遲、封包遺失、 signaling • overhead • –本章節焦點著重在handover latency • ‧MN從一個foreign network 移動到另一個foreign • network 時

  5. Related WorkMIPv6 and HMIPv6 • 如同前面所提到的MIPv6仍然是有些問題 • 像是換手延遲、封包遺失和signaling overhead • Hierarchical Mobile IPv6(階層式Mobile IPv6) • "Hierarchical Mobile IPv6 Mobility Management (HMIPv6)“, IETF RFC 4140, Aug. 2005 • HiMIPv6延伸了Mobile IPv6的功能 • 考慮到區域行動性的處理

  6. Related WorkSummary • Mobile IPv6仍然是有些問題存在 • Hierarchical Mobile IPv6 • 延伸了MIPv6的功能 • 改善換手延遲 • 考慮到local mobility handling • 須要修改到MN • Proxy Mobile IPv6(PMIPv6) • 改善換手延遲更優於HMIPv6 • 不須要修改到MN

  7. NetLMM ApproachOverview • NetLMM 為IETF所制訂的網際網路標準 • 屬於一種基於網路移動性管理的協定) • 必須依賴眾多通訊基地台的合作來代替MN做移動性的管理)

  8. NetLMM ApproachOverview • LMA(Local Mobility Anchor) • MAG(mobile access gateway) • NETLMM domain • (network-based localized mobility management domain) Home Network LMA

  9. NetLMM ApproachOverview • LMA(Local Mobility Anchor) • MAG(mobile access gateway) • NETLMM domain • (network-based localized mobility management domain) Home Network MAG LMA MAG

  10. NetLMM ApproachOverview • LMA(Local Mobility Anchor) • MAG(mobile access gateway) • NETLMM domain • (network-based localized mobility management domain) Home Network MAG LMA NETLMM domain MAG

  11. NetLMM ApproachOverview • LMA(Local Mobility Anchor) • MAG(mobile access gateway) • NETLMM domain • (network-based localized mobility management domain) Home Network MN MAG LMA Foreign Network NETLMM domain CN MAG MN

  15. NetLMM ApproachMessage Flow (3) AAA reply with profile

  16. NetLMM ApproachMessage Flow (4) PBU with MN-ID

  17. NetLMM ApproachMessage Flow (5) AAA query with MN-ID

  18. NetLMM ApproachMessage Flow (6) AAA reply

  19. NetLMM ApproachMessage Flow (7) PBA with MN-ID, home network prefix option

  20. NetLMM ApproachMessage Flow (8)Bidirectional tunnel setup & Router Advertisement

  21. NetLMM ApproachHandoff ’s Message Flow Home-of-Address Home Network MAG1 LMA MN Foreign Network NETLMM domain CN MAG2

  22. NetLMM ApproachHandoff ’s Message Flow Home Network MAG1 LMA Foreign Network Move NETLMM domain MN CN MAG2 Home-of-Address

  23. NetLMM ApproachHandoff ’s Message Flow Home Network MAG1 LMA Foreign Network MN Attachment NETLMM domain MN CN MAG2 Home-of-Address

  24. NetLMM ApproachHandoff ’s Message Flow Home Network MAG1 LMA Proxy Binding Update message Foreign Network NETLMM domain MN CN MAG2 Home-of-Address

  25. NetLMM ApproachHandoff ’s Message Flow Home Network MAG1 LMA Proxy Binding Ack Foreign Network NETLMM domain MN CN MAG2 Home-of-Address

  26. NetLMM ApproachHandoff ’s Message Flow Home Network MAG1 LMA Foreign Network Router advertisement NETLMM domain MN CN MAG2 Home-of-Address
