swift google delay-based dc-cc
Google is so great! swift is a delay based congestion control mechanism that has applied in Google data center, which targets to maintain an extreme low latency and near-zero packet drops.
Its key ideas includes accurate RTT measurement, simple AIMD mechanism, decomposing the latency to fabric and end-host latency to work at IOPS- and throughput-intensive scenarios, allowing pacing so that cwnd can <1 to avoid congestion in incast scenario, flow and topology scaling to adapt to various levels of topo and flow.
