Pushing the Performance Limits of Datacenter Networks

PowerTCP is a fine-grained congestion control algorithm designed to satisfy the increasingly stringent throughput and latency requirements of datacenter networks. PowerTCP leverages the novel notion of Power that bridges the gap between inflight-based and rate-based schemes. PowerTCP comes with two flavors depending on the type of network feedback: based on In-band Network Telemetry (INT) and based on delay or Round-Trip-Time (RTT).
