2019-10-17tcp: Init cwnd from ssthresh.Sergey Ivanushkin1-1/+7
Set high ssthresh out of the box and make configurable Type: fix Signed-off-by: Sergey Ivanushkin <sergey.ivanushkin@enea.com> Change-Id: Iba1549b4ee55e51468ad0b28ef3d26a85fa9cae0
2019-09-25tcp: use sacks for timer based recoveryFlorin Coras1-6/+2
Type: feature If available, reuse sack scoreboard in timer triggered retransmit to minimize spurious retransmits. Additional changes/refactoring: - limited transmit updates - add sacked rxt count to scoreboard - prr pacing of fast retransmits - startup pacing updates - changed loss window to flight + mss Change-Id: I057de6a9d6401698bd1031d5cf5cfbb62f2bdf61 Signed-off-by: Florin Coras <fcoras@cisco.com>

2019-06-25tcp: delivery rate estimatorFlorin Coras1-1/+1
Type: feature First cut implementation with limited testing. The feature is not enabled by default and the expectation is that cc algorithms will enable it on demand. Change-Id: I92b70cb4dabcff0e9ccd1d725952c4880af394da Signed-off-by: Florin Coras <fcoras@cisco.com>

2018-11-13tcp: cubic improvementsFlorin Coras1-9/+25
- avoid cwnd excessive increments on threshold changes - fix K computation when fastconvergence is on Change-Id: I99c36abc879e63aecc0617f7aed5a2f68430ba71 Signed-off-by: Florin Coras <fcoras@cisco.com>

2018-11-09tcp: basic cubic implementationFlorin Coras1-0/+194
Because the code is not optimized, newreno is still the default congestion control algorithm. Change-Id: I7061cc80c5a75fa8e8265901fae4ea2888e35173 Signed-off-by: Florin Coras <fcoras@cisco.com>
