DCTCP (Data Center TCP) implementation.DCTCP congestion control algorithm aims to maximise throughput and minimiselatency in data center networks by utilising the proportion of ExplicitCongestion Notification (ECN) marked packets received from capable hardware as acongestion signal.Highlights:Implemented as a mod_cc(4) module.ECN (Explicit congestion notification) processing is done differently fromRFC3168.Takes one-sided DCTCP into consideration where only one of the sides is usingDCTCP and other is using standard ECN.IETF draft: http://tools.ietf.org/html/draft-bensley-tcpm-dctcp-00Thesis report by Midori Kato: https://eggert.org/students/kato-thesis.pdfSubmitted by: Midori Kato <katoon@sfc.wide.ad.jp> and Lars Eggert <lars@netapp.com> with help and modifications from hirenDifferential Revision: https://reviews.freebsd.org/D604Reviewed by: gnn
