11. TCP Vegas was deployed as the default congestion control method for DD-WRT firmware v24 SP2. 12. Congestion control then becomes a distributed optimisation algorithm.13. Acknowledgements are transmitted as reliably as the congestion control mechanism in use requires, possibly completely reliably. 14. Open-loop flow control is used by UBR services ( see traffic contract and congestion control ). 15. Scalable TCP modifies the congestion control algorithm. 16. Similar to TCP congestion control on the internet, frame loss is built into the operation of 802.11. 17. Congestion control can therefore be achieved by reducing the rate of packet production at hosts with long queues.18. Four Multipath TCP congestion control schemes are currently supported by the Multipath TCP implementation in the Linux kernel. 19. UDP is only suited for low-bandwidth communication unless you implement congestion control that's approximately as sophisticated as TCP's. 20. UDT is built on top of User Datagram Protocol ( UDP ), adding congestion control and reliability control mechanisms.
