In recent years, we have seen a significant enhancement in the performance of standard Transmission Control Protocol (TCP) congestion control algorithms. The number of packet drops and high round-trip time (RTT) are indications of network congestion. Many congestion control mechanisms have been proposed to overcome the challenge of achieving increased throughput and reduced latency. We have reviewed many TCP congestion control algorithms which are discussed in the literature. The limitation of the existing work is a trade-off between throughput, loss ratio, and delay. It is not possible for any algorithm to outperform the existing algorithm in terms of all the performance measures. We attempt to achieve the best performance while our proposed algorithm competes with CUBIC and Bottleneck Bandwidth and Round-trip propagation time (BBR). According to the observed results in the literature, TCP Veno dominates among other existing algorithms. We have proposed a bandwidth-delay product (BDP) based TCP (BDP-Veno) congestion control algorithm by modifying Veno to incorporate the information of BDP of the bottleneck. The proposed algorithm is implemented using ns-2. Moreover, we have analyzed the performances of standard TCP congestion control algorithms by considering different network scenarios. Our proposed algorithm performs better compared to other existing TCP congestion control schemes such as Reno, Newreno, BIC, CUBIC, Vegas, Veno, and Compound TCP in terms of average throughput in most of the scenarios. In Scenario 1, our proposed algorithm enhances the throughput with respect to Veno by 57%. Further, we have also compared the throughput with BBR using ns3 where we receive comparable throughput with BBR.

一种基于带宽延迟乘积的改进型Veno，用于高速网络：BDP-Veno


近年来，我们看到标准传输控制协议（TCP）拥塞控制算法的性能显着增强。数据包丢失数量和较长的往返时间 (RTT) 表明网络拥塞。已经提出了许多拥塞控制机制来克服实现增加吞吐量和减少延迟的挑战。我们回顾了文献中讨论的许多 TCP 拥塞控制算法。现有工作的局限性是吞吐量、丢失率和延迟之间的权衡。任何算法都不可能在所有性能指标上都优于现有算法。我们试图在我们提出的算法与 CUBIC 和瓶颈带宽和往返传播时间 (BBR) 竞争的同时实现最佳性能。根据文献中观察到的结果，TCP Veno 在其他现有算法中占据主导地位。我们通过修改Veno以纳入瓶颈的BDP信息，提出了一种基于带宽延迟积（BDP）的TCP（BDP-Veno）拥塞控制算法。所提出的算法是使用 ns-2 实现的。此外，我们还考虑了不同的网络场景，分析了标准 TCP 拥塞控制算法的性能。与其他现有的 TCP 拥塞控制方案（例如 Reno、Newreno、BIC、CUBIC、Vegas、Veno 和 Compound TCP）相比，我们提出的算法在大多数场景的平均吞吐量方面表现更好。在场景 1 中，我们提出的算法将 Veno 的吞吐量提高了 57%。此外，我们还使用 ns3 与 BBR 进行了吞吐量比较，我们获得了与 BBR 相当的吞吐量。
