A Spectrum Of TCP-Friendly Window-Based Congestion Control Algorithms
White Papers In window-based congestion control schemes, increase rules determine how to probe available bandwidth, whereas decrease rules determine how to back off when losses due to congestion are detected. This paper presents a comprehensive study of a new...

Influence Of False Congestion Alarms On Performance For Congestion Control Based On Dynamic Window Flow Mechanism In Wireless Networks
White Papers The congestion detection mechanism of congestion control based on dynamic window flow control, which is widely used for reliable window protocols such as TCP, is well-known to be simple, but it may raise false alarms: a sender usually interprets...

Sender Side Intelligence For TCP Throughput Enhancement In Wired-Cum-Wireless Network
White Papers The key idea to determine the Optimal Congestion Window for a TCP Sender, in a particular network scenario (that corresponds to the fair share of that connection) and keep this congestion window a constant to a point where the fair share in the...

TCP With Sender-Based Delay Control
White Papers This paper describes a congestion control method for TCP that adjusts the transmission rate of a TCP connection by changing not only the congestion window size as in normal TCP, but also by delaying the transmission of packets at the sender.

A Burstiness Control For High Speed Long Distance TCP
White Papers This has stimulated intensive research on improving TCP congestion control algorithm in order to sustain large congestion window and high throughput. Most of these works however focus almost exclusively on window control algorithm that controls the...

TCP-Friendly SIMD Congestion Control And Its Convergence Behavior
White Papers Window-based congestion control schemes use increase rules to probe available bandwidth, and decrease rules to back off when congestion is detected. This paper proposes a novel window-based congestion control algorithm called SIMD (Square-Increase...

TCP With Adaptive Pacing For Multihop Wireless Networks
White Papers This paper introduces a novel congestion control algorithm for TCP over multihop IEEE 802.11 wireless networks implementing rate-based scheduling of transmissions within the TCP congestion window. It shows how a TCP sender can adapt its...

Congestion Control: SCTP Vs TCP
White Papers This paper characterizes an inefficiency in the current speciation of SCTP's congestion control, which degrades performance (more than necessary to be 'TCP-friendly') when there are multiple packet losses in a single window.

Is Tampered-TCP Really Effective For Getting Higher Throughput In The Internet?
White Papers This paper focuses on a tampered-TCP in which the increase and decrease ratio of the congestion window size were changed during the congestion avoidance phase. This paper examines the effectiveness of tampered-TCP whose congestion control mechanism...

End-to-End Bandwidth Estimation In TCP To Improve Wireless Link Utilization
White Papers TCP Westwood (TCPW) is a sender-side only modification of TCP Reno congestion control that exploits an end-to-end bandwidth estimation mechanism to set the values of Slow-Start-Threshold and Congestion-Window after a congestion episode that is...

Improving TCP Performance In High Bandwidth High RTT Links Using Layered Congestion Control
White Papers This paper proposes Layered TCP (LTCP for short), a simple layering technique for the congestion window response of TCP to make it more scalable in highspeed, high RTT networks. LTCP is a two dimensional congestion control framework - the...

UDT: An Application Level Transport Protocol For Grid Computing
White Papers These problems are due to slow loss-recovery, a RTT bias inherent in its AIMD congestion-control algorithm, and the bursting data flow caused by its window control. UDT has a congestion control mechanism that maintains efficiency, fairness and...

Mathematical Analysis Of Westwood+ TCP Congestion Control
White Papers The estimate is used to adaptively decrease the congestion window and slow start threshold after congestion so that it can be said that Westwood+ TCP substitutes the classic multiplicative decrease with an adaptive decrease paradigm.
