BBR stands for Bottleneck Bandwidth and Round-trip time, which refers to a networking algorithm designed to improve internet performance in situations where network congestion occurs. It is a congestion control mechanism that estimates the available bandwidth and the network's round-trip time, ultimately optimizing the delivery of data packets across the internet.
The BBR algorithm works by continuously monitoring network conditions, measuring the round-trip time of packets and the amount of bandwidth available. It uses these measurements to adjust the sending rate of packets, also known as the sending rate of the congestion window. This dynamic adjustment aims to prevent overloaded or underutilized networks, minimizing delay, and maximizing throughput.
The BBR algorithm differs from traditional congestion control mechanisms, such as TCP (Transmission Control Protocol), as it focuses on maximizing throughput and minimizing queuing delay, rather than avoiding packet loss. It achieves this through intelligent pacing, allowing data to be sent at a rate that aligns with the available network capacity efficiently.
The BBR algorithm has gained significant attention and adoption due to its ability to deliver faster and more stable internet connections. It has particularly proven effective in improving streaming quality, reducing buffering times, and enhancing user experience in various online services, such as video streaming platforms, online gaming, and cloud computing applications.
Overall, BBR is an important networking algorithm that dynamically adjusts the sending rate and optimizes data delivery, ensuring improved internet performance and user satisfaction, especially in congested network environments.
