SRF TCP: A TCP-Friendly and Fair Congestion Control Method for High-Speed Networks
نویسندگان
چکیده
TCP Reno congestion control carries two issues. First, its performance is poor in high-speed networks. To solve this TCP Reno drawback, HighSpeed TCP and Scalable TCP were proposed. However, the fairness between these proposed TCP and TCP Reno is not considered, when both connections coexist. Second, TCP Reno connections share bandwidth unfairly, when TCP flows with different RTTs use the same link. Many approaches have been proposed to solve this issue. However, no single method has been proposed to solve both issues. In this paper, we propose Square Root Fair TCP (SRF TCP). SRF TCP congestion control (1) sends packets efficiently in high-speed networks, (2) is TCP-friendly with TCP Reno and (3) shares fair bandwidth between flows with different RTTs. We evaluate the capabilities of SRF TCP through computer simulations and compare it with TCP Reno, HighSpeed TCP and Scalable TCP.

TCP Westwood and Easy RED to Improve Fairness in High-Speed Networks
TCP Westwood (TCPW) is a sender-side only modification of TCP Reno congestion control, which exploits end-to-end bandwidth estimation to properly set the values of slow-start threshold and congestion window after a congestion episode. This paper aims at showing via both mathematical modeling and extensive simulations that TCPW significantly improves fair sharing of high-speed networks capacity ...

Mobile ad hoc network congestion control is a significant problem. Standard mechanism for congestion control (TCP), the ability to run certain features of a wireless network, several mutations are not common. In particular, the enormous changes in the network topology and the joint nature of the wireless network. It also creates significant challenges in mobile ad hoc networks (MANET), density ...
متن کاملH-TCP: TCP for high-speed and long-distance networks
In this paper we present a congestion control protocol that is suitable for deployment in highspeed and long-distance networks. The new protocol, H-TCP, is shown to fair when deployed in homogeneous networks, to be friendly when competing with conventional TCP sources, to rapidly respond to bandwidth as it becomes available, and to utilise link bandwidth in an efficient manner. Further, when de...
متن کاملAdaptive TCP for Effective and Fair Utilization of High Bandwidth-Delay Product Networks
The fairness (or TCP-friendliness) of recent high-speed TCP proposals for high bandwidth-delay product networks is generally poor. We believe that the lack of the TCP-friendliness of high-speed TCP proposals stems from their ineffectiveness in detecting competing TCP ¤ows. We suggest a competition detection mechanism for a single TCP ¤ow to detect the presence of competing TCP ¤ows and propose ...
متن کاملTeraflows over Gigabit WANs with UDT
The TCP transport protocol is currently inefficient for high speed data transfers over long distance networks with high bandwidth delay products. The challenge is to develop a protocol which is fast over networks with high bandwidth delay products, fair to other high volume data streams, and friendly to TCP-based flows. We describe here a UDP based application level transport protocol named UDT...
