  • Monami6


Mipv6

MIPv6

  • MIP技術是由Internet Engineering Task Force (IETF)所提出的一個標準通訊協定

  • 讓用戶端在網路漫遊時,能夠保有一個固定的IP 位置,使第三層的連線不至於中斷

  • 其原理是透過一個固定不變的 Home Address (HoA) 對映到目前用戶端所在網路的 Care-of Address (CoA)

  • Monami6是IETF其中一組Working Group

  • 負責制定有關Mobile Node and Multiple Interfaces in IPv6的部份

  • 目標是讓使用者可以同時向Home Agent (HA)註冊多個位置

Reference:draft-ietf-monami6-multiplecoa-04.txt


Monami6 1 2

Monami6情境(1/2)

  • 提供Video Stream服務的伺服器,可以同時透過多種無線傳輸介面送出影像

    • 3G傳送解析度較低的影像

      傳送範圍較遠,但影像品質較差

    • WLAN傳送解析度較高的影像

      範圍較近但影像品質較佳


Monami6 2 2

Monami6情境(2/2)

  • 當使用者在機場等候登機時,使用WLAN上網抓取資料。但是已經要登機,必須要離開目前WLAN範圍,此時可以同時利用3G上網,繼續抓取剩下未完成的資料,一邊向登機閘門

Reference:draft-ietf-monami6-multihoming-motivation-scenario-03

大綱

  • 背景介紹

  • 實作Monami6 (Over MIPv6)

  • 訊息流程圖

  • 註冊流程示意圖

    (Binding update to HA)


Monami6 over mipv6

實作Monami6 (Over MIPv6)

  • 在原本保留的欄位中,新增一個欄位,用來紀錄Binding Unique Identifier (BID)

  • MN上面的每張網路介面都有各自的BID,此BID不可重覆

  • 在MN發送BU時,會夾帶該網路介面之BID

  • 在HA收到BU之後,會將HoA、CoA、BID當作hash key值,產生Binding Entry Key


Monami6 over mipv61

實作Monami6 (Over MIPv6)

  • 利用這個Binding Entry Key去尋找目前的Binding Table中有無相符之Entry

    • 有,則將該筆Entry換成新收到的這筆紀錄

    • 無,則將收到的紀錄新增一個Binding Entry
