In the current internet, more than 90% of the web applications use TCP as transport layer protocol. Google in late 2016 proposed the Bottleneck Bandwidth and Round-trip propagation time (BBR) as a new congestion control algorithms to improve the overall network performance. Unlike the existing loss-based congestion control algorithms, BBR works without filling the buffer of the bottlenecks, thus it reduces packet losses and minimizes the end-to-end delays; therefore, draws attention from many researchers. In this paper, firstly, we observe the BBR¡¯s behavior characteristics, then decribe the current standardization, R&D and research issues of BBR algorithm.
