Improving Throughput in Real-time Simulation of High Speed Tcp Protocols

چکیده
Round Trip Time (RTT) estimation is an important variable for efficient fairness bandwidth flows of different RTT. This paper propose a stabilized rate scheme to enhance the RTT fairness on high speed Transmission Control Protocols (TCP) namely BIC-TCP, FAST, H-TCP and LTCP. The rate of window growth is stabilized in high speed protocols from the current window size, such that competing flows adjust their window size. The conditions for parallel RTT’s samples are derived to eliminate the RTT fairness problems in high speed protocols. We then investigate the impact of RTT fairness and benefits of using stabilized rate scheme on high speed protocols BIC-TCP, FAST, H-TCP and LTCP. The results indicate under varying levels of loss synchronization, stabilized rate scheme in high speed protocols provides RTT fairness better than standard TCP. Our results also indicate that even small degradation of RTT fairness can severely impair the throughput performance of high speed protocols.

The Transmission Control Protocol (TCP) is the mostly used protocol for data transmission over terrestrialwire line networks. However, TCP‟s congestion control algorithm wasn‟t created to match the special characteristics (long delay and high Bit Error Rate) of satellite links, resulting in a drastically performance degradation. For high speed satellite communication networks to match its chara...

Parallel download protocols that establish multiple TCP connections to distributed replica servers have the potential to reduce file download time and to improve the quality of realtime multimedia downloads. Unfortunately, parallel download protocols are also inherently unfair towards single-flow downloads. This paper presents TCP-ROME, a parallel download protocol that allows a dynamic mitigat...
متن کاملSteady state and transient state analyses of TCP and TCP-friendly rate control mechanism using a control theoretic approach
In recent years, various real-time applications in the Internet have been emerging with rapid increase of the network bandwidth. A real-time application traditionally uses either UDP (User Datagram Protocol) or TCP (Transmission Control Protocol) as its transport layer protocol. However, using either UDP or TCP is insufficient for most real-time applications because of lacking a smooth rate con...
متن کاملQTCP: An Approach for Exploring Inter and Intra Protocols Fairness
TCP provides communication service however the network congestion is one of the core issues, it occurs when a link carry so much data, and effects on delay, packet loss rate and fairness. When the available bandwidth becomes very high, TCP, as tuned today, does not perform well. Several high-speed variants of TCP have been implemented to resolve the congestion issue , such as High-Speed TCP (HS...
