      4DCTCP (DataCenter TCP)
      5======================
      6
      7DCTCP is an enhancement to the TCP congestion control algorithm for data
      8center networks and leverages Explicit Congestion Notification (ECN) in
      9the data center network to provide multi-bit feedback to the end hosts.
     10
     11To enable it on end hosts::
     12
     13  sysctl -w net.ipv4.tcp_congestion_control=dctcp
     14  sysctl -w net.ipv4.tcp_ecn_fallback=0 (optional)
     15
     16All switches in the data center network running DCTCP must support ECN
     17marking and be configured for marking when reaching defined switch buffer
     18thresholds. The default ECN marking threshold heuristic for DCTCP on
     19switches is 20 packets (30KB) at 1Gbps, and 65 packets (~100KB) at 10Gbps,
     20but might need further careful tweaking.
