Abstract:
This memo describes Datacenter TCP (DCTCP), an improvement to TCP
congestion control for datacenter traffic. DCTCP uses improved
Explicit Congestion Notification (ECN) processing to estimate the
fraction of bytes that encounter congestion, rather than simply
detecting that some congestion has occurred. DCTCP then scales the
TCP congestion window based on this estimate. This method achieves
high burst tolerance, low latency, and high throughput with shallow-
buffered switches.
