【摘要】：為了增強衛(wèi)星網(wǎng)絡(luò)中TCP協(xié)議的性能,首先提出了一種衛(wèi)星鏈路下的TCP性能模型,該模型可以反映出帶寬約束下TCP性能相關(guān)參數(shù)對有效吞吐率的影響;其次,基于該模型提出了一種動態(tài)規(guī)劃解決方案,通過求解吞吐率代價函數(shù),得到優(yōu)化的數(shù)據(jù)傳輸策略,該方案不僅能夠方便地平衡衛(wèi)星基站對TCP吞吐率或公平性的要求,還可幫助TCP協(xié)議適應(yīng)衛(wèi)星衰減鏈路的各項特征變化。仿真試驗表明:該算法能夠有效地改進衛(wèi)星傳輸TCP的性能。
[Abstract]:In order to enhance the performance of TCP protocol in satellite networks, a TCP performance model based on satellite links is proposed, which can reflect the influence of TCP performance parameters on the effective throughput under bandwidth constraints. Based on this model, a dynamic programming solution is proposed. By solving the throughput cost function, an optimized data transmission strategy is obtained. This scheme not only can easily balance the requirements of TCP throughput or fairness for satellite base stations. It can also help the TCP protocol to adapt to the variation of satellite attenuation link characteristics. Simulation results show that the proposed algorithm can effectively improve the performance of satellite transmission TCP.
