TCP BBR is a high performance TCP congestion con-trol, which maximizes the utilization of the bottle-neck link and avoids the bufferbloat. In the bottle-neck link with deep buffer probable to be bufferbloat,the throughput of TCP BBR co-existing with TCP CUBIC decrease because of the sequential time-outs. In this paper, we propose a new high per-fromance congestion-based congestion control TCPBBR+, which can yield large throughput even whenco-existing with TCP CUBIC in the bottleneck linkwith deep buffer. We found that TCP BBR+ canget high performance in the network with the deepbuffer co-existing with TCP CUBIC, not decreasingthe total throughput.
