各种无线接入技术的日益增长的可用性促进了对移动的视频应用的日益增长的需求。基于流控制传输协议（SCTP）的并发多路径传输（CMT）利用其并行传输和带宽聚合特性提高了无线视频传输性能。然而，由于较低层的不确定性，例如无线信道的变化，仅在传输层部署的现有CMT解决方案不够准确。此外，与流行的基于传输控制协议（TCP）的流相比，基于CMT的视频传输可能使用过多的BW，这导致网络资源的不公平共享。本文提出了一种新的跨层公平驱动（CL/FD）的SCTP的CMT解决方案（CMT-CL/FD），以提高视频传输性能，同时保持公平竞争的TCP流。CMT-CL/FD利用跨层方法来监控和分析路径质量，包括数据链路层的无线信道测量和传输层的速率/带宽估计。此外，一个创新的基于窗口的流量控制机制，以平衡交付的公平性和效率。最后，CMT-CL/FD智能地将视频数据分配到不同的路径上，这取决于它们的估计质量，以减轻数据包的重新排序和丢失，在TCP友好的流量控制的约束下。仿真结果显示CMT-CL/FD在视频传输性能和TCP友好性方面优于现有解决方案。
The growing availability of various wireless access technologies promotes increasing demand for mobile video applications. Stream control transmission protocol (SCTP)-based concurrent multipath transfer (CMT) improves the wireless video delivery performance with its parallel transmission and bandwidth (BW) aggregation features. However, the existing CMT solutions deployed at the transport layer only are not accurate enough due to lower layer uncertainties, such as variations of the wireless channel. In addition, CMT-based video transmission may use excessive BW in comparison with the popular Transmission Control Protocol (TCP)-based flows, which results in unfair sharing of network resources. This paper proposes a novel cross-layer fairness-driven (CL/FD) SCTP-based CMT solution (CMT-CL/FD) to improve video delivery performance, while remaining fair to the competing TCP flows. CMT-CL/FD utilizes a cross-layer approach to monitor and analyze path quality, which includes wireless channel measurements at the data-link layer and rate/BW estimations at the transport layer. Furthermore, an innovative window-based mechanism is applied for flow control to balance delivery fairness and efficiency. Finally, CMT-CL/FD intelligently distributes video data over different paths depending on their estimated quality to mitigate packet reordering and loss, under the constraint of TCP-friendly flow control. Simulation results show how CMT-CL/FD outperforms existing solutions in terms of both video delivery performance and TCP-friendliness.
