本篇論文主要是將網路編碼結合多路徑傳輸協定，在連線路徑匹配程度不同的狀況下，進一步改善其連線品質，並且實做在Linux kernel中量測其在真實環境中的效能，針對不同的網路情境測量，除了穩定的伺服器之外，也包含一般使用者的上傳情境，以及多路徑傳輸不同匹配程度，在加入網路編碼之後，都獲得了不同程度的優化。;With the evolution of network communication technology, many smart mobile device equipped with muliple interface. More and more server support multipath transmission to provide better quality of service than TCP. In the future, the multipath technology will focus on not only stable server but also every unstable user to upload. Therefore, the variation between different path and the quality of server become an important issue.
Multi-path TCP (MPTCP) is an extension of TCP that allows multiple interfaces to transmit simultaneously. MPTCP can provide better performance than TCP. The optimization for MPTCP is more and more complete. But the problem of packet lose suffered TCP also appear on MPTCP. The variation between each path and packet loss let the overall performance get worse especially for unstable server. Therefore, we decide to solve this problem by network coding.
The main purpose in this paper is the combination of MPTCP and network coding to improve the performance in several situation above. And we also make an implemetation in Linux kernel for real-world experiment. The scenarios include variation condition of path and qualiaty of server. Finally, our strategy can handle different condition and get higher performance.
