Abstract:
This memo describes Datacenter TCP (DCTCP), an improvement to TCP
congestion control for datacenter traffic. DCTCP enhances 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.
