BBR（Bottleneck Bandwidth and Round-trip propagation time）是由Google开发的一种网络拥塞控制算法，旨在优化TCP连接的性能。它主要通过动态调整TCP的拥塞窗口和发送方的数据包发送速率来提高网络吞吐量和减少延迟。BBR的主要特点包括：文章源自合一学院-https://unvmax.com/%e3%80%8clinux%e4%b8%80%e9%94%ae%e5%ae%89%e8%a3%85%e8%84%9a%e6%9c%ac%e3%80%8dbbr-bbrplus%e5%8a%a0%e9%80%9f%e4%bc%98%e5%8c%96%e6%95%99%e7%a8%8b-%e6%8e%a8%e8%8d%90%e6%9c%80%e4%bd%b3%e9%83%a8%e7%bd%b2-ID75017
基于网络状况的自动调整：BBR能够根据网络的拥塞情况和往返时延（RTT）自动调整数据包的发送速率，从而实现更高的带宽利用率和更低的延迟。文章源自合一学院-https://unvmax.com/%e3%80%8clinux%e4%b8%80%e9%94%ae%e5%ae%89%e8%a3%85%e8%84%9a%e6%9c%ac%e3%80%8dbbr-bbrplus%e5%8a%a0%e9%80%9f%e4%bc%98%e5%8c%96%e6%95%99%e7%a8%8b-%e6%8e%a8%e8%8d%90%e6%9c%80%e4%bd%b3%e9%83%a8%e7%bd%b2-ID75017
