Data Center TCP

  "DCTCP is an enhancement to the TCP congestion control algorithm
   for data center networks. It leverages Explicit Congestion
   Notification (ECN), a feature which is increasingly becoming
   available in modern data center switches. DCTCP sources extract
   multi-bit feedback on congestion from the single-bit stream of
   ECN marks by estimating the fraction of marked packets. In doing so,
   DCTCP sources react to the extent of congestion, not just the
   presence of congestion as in TCP.  This finer level of control
   allows DCTCP to operate with very low buffer occupancies while
   simultaneously achieving high throughput.

A DCTCP patch (version 1.0.0) is now available. The patch applies
to Linux
