About this title

Synopsis:

隨著科技的進步，現今許多的技術瓶頸已經不斷的被突破。以軟體定義網路(SDN)為例，其正挑戰著舊有的網路環境。但是車輛系統一直是走封閉的系統環境，車輛製造商以隱私、安全、無法即時反應車輛資訊以及網路速度太慢為由，一直固守著傳統留下的原則，維持各自一套不為人知的資訊系統。高速的行動通訊系統，加上本研究以軟體定義網路的架構導入到車載資通訊系統(Telematics)的新應用，使得車載資通訊系統有統一的協定而又不失其保密性。 本研究促使多元應用提供車用標準介面及函式，結合車載資通訊系統跟軟體定義網路，達到相輔相成的效果。本研究軟體定義網路(SDN)使用OpenFlow交換器1.3版與NOX控制器1.3版為基礎，將車載CAN資料解譯之後包裝在OpenFlow控制訊息中。使得控制器與交換器在發送或回應訊息可以用OpenFlow訊息格式封裝後發送或接收。 本研究最重要的是提供車載資通訊系統開放並標準化的介面及應用，透過新的應用介面對有OpenFlow及非OpenFlow機制協定做比較。發現在模擬少數車輛時，以非OpenFlow的機制在傳送接收訊息，延遲時間會比較短。但在模擬多台車輛時，由於OpenFlow機制針對多執行緒的效能進行處理，所以延遲時間有較佳的效果，而非OpenFlow對此沒有提及，導至延遲時間長短不一。本研究測試得到：在32個模擬車輛時，使用OpenFlow的延遲時間，減少約6.4%。由此可見，當連線數愈多時，OpenFlow的整體機制會優於非OpenFlow的整體機制。
