The current User Datagram Protocol (UDP) causes unfairness and bufferbloats to delay sensitive applications due to the uncontrolled congestion and monopolization of available bandwidth.This causes call drops and frequent communication/connection loss in delay sensitive applications such as VoIP. We present a Responsive Control Protocol using Bottleneck Bandwidth and Round trip propagation time (RCP-BBR) as an alternate solution to UDP. RCP-BBR achieves low latency, high throughput, and low call drops ratio by efficiently customizing Transmission Control Protocol (TCP) Bottleneck Bandwidth and Round-trip propagation time (TCP-BBR) congestion control. We conducted comprehensive experiments, and the results show that proposed protocol achieves better throughput over UDP in stable networks. Moreover, in unstable and long-distanced networks, RCP-BBR achieved smaller queues in deep buffers and lower delays as compared to UDP, which performed poorly by keeping delays above the call drop threshold.

用于延迟敏感的实时应用的基于 BBR 的拥塞控制

由于可用带宽不受控制的拥塞和垄断，当前的用户数据报协议 (UDP) 会导致不公平和缓冲膨胀来延迟敏感应用程序。这会导致呼叫中断和延迟敏感应用程序（如 VoIP）中频繁的通信/连接丢失。我们提出了一个使用瓶颈带宽和往返传播时间 (RCP-BBR) 作为 UDP 替代解决方案的响应控制协议。RCP-BBR 通过高效定制传输控制协议 (TCP) 瓶颈带宽和往返传播时间 (TCP-BBR) 拥塞控制来实现低延迟、高吞吐量和低掉话率。我们进行了全面的实验，结果表明，所提出的协议在稳定的网络中比 UDP 实现了更好的吞吐量。此外，在不稳定和远距离的网络中，
