移动终端通常通过诸如Wi-Fi接入点（AP）的无线站访问Internet。如果连接到同一站/AP的终端数量增加，它们的吞吐量就会减少，因为它们共享站/AP的带宽。为了解决这一问题，需要在终端之间建立一定的流量分配机制。本文提出了一种基于MPTCP （MultiPath TCP）协议的移动终端动态流量分配系统，该系统通过专用VPN服务器连接到Internet。在该方案中，VPN服务端跟踪所有站/ ap的情况，并相应地在VPN服务端和某些终端之间切换一些路径。仿真实验表明，该方法可以有效地在多终端之间分配流量。
Mobile terminals usually have access to the Internet via a wireless station such as a Wi-Fi access point (AP). If the number of such terminals connected to the same station/AP increases, their throughput decreases because they share bandwidth of the station/AP. To solve this problem, some traffic distribution mechanism among terminals is necessary. In this paper, we propose a dynamic traffic distribution system among multiple mobile terminals connecting to the Internet via a special VPN server with MultiPath TCP (MPTCP). In this scheme, the VPN server keeps track of conditions of all stations/APs and switches some paths between the VPN server and some terminals accordingly. Simulation experiments shows that the proposed method can distribute traffic among multiple terminals effectively.
