    Abstract: 無線網路通訊技術的發展日新月異,行動裝置的普及直接也間接地促使了同一裝置使用多個網路介面的應用。

    在傳輸層的多路徑傳輸控制協定 (MPTCP) 可在具多網路型態介面的端點裝置下同時進行彼此的資料傳輸,MPTCP 不僅相容於現今的網路規格並且能夠確實的提升傳輸效率以及降低延遲,對於日後物聯網的串流應用有著莫大的幫助。
    為了提升 MPTCP 的效能,壅塞控制、公平性、以及路徑排程已經變成許多研究爭相討論的議題。

    在此論文中,我們利用了可適應性的壅塞窗格耦合、預測網路狀態、以及亂序傳輸的控制器,最終提出了藉由允許亂序傳輸以結合壅塞控制以及路徑排程的演算法以全盤解決現在 MPTCP 中潛在的問題。
    我們將此演算法寫入 Linux kernel 內並在真實世界的網路下做量測,最後的實驗環境包含了最小網路拓樸、共同網路瓶頸、以及獨立網路瓶頸。;With development of wireless communication technologies, mobile devices are commonly equipped with multiple network interfaces and ready to adopt emerging transport layer protocols such as multipath TCP (MPTCP).
    The protocol is specifically useful for Internet of Things streaming applications with critical latency and bandwidth demands.
    To achieve full potential of MPTCP, major challenges on congestion control, fairness, and path scheduling are identified and draw considerable research attention.
    In this paper, we propose a joint congestion control and scheduling algorithm allowing out-of-order transmission as an overall solution.
    It is achieved by adaptive window coupling, congestion discrimination, and out-of-order transmission enabled scheduling.
    The algorithm is implemented in the Linux kernel for real-world experiments.
    Favorable results are obtained in minumum topology and both shared or distinct bottleneck scenarios.
