Performance Evaluation and Comparison of Westwood+, New Reno, and Vegas TCP Congestion Control
White Paper TCP congestion control has been designed to ensure Internet stability along with fair and efficient allocation of the network bandwidth. During the last decade, many congestion control algorithms have been proposed to improve the classic Tahoe/Reno... [14 Jan 2008]
A New Congestion Control Mechanism of TCP With Inline Network Measurement
White Paper This paper proposes a novel congestion control mechanism of TCP, by using an inline network measurement technique. By using information of available bandwidth of a network path between sender and receiver hosts, it constructs quite a different... [14 Jan 2008]
Equation-Based Approach to TCP-Compatible Multicast Congestion Control for Layered Transmission in Low-Multiplexing Environments
White Paper In this paper, the applicability of an equation-based mechanism to congestion control for a protocol which bases its join and leave actions on the calculation of the TCP response function is investigated. [14 Jan 2008]
TCP Westwood: End-to-End Congestion Control for Wired/Wireless Networks
White Paper TCP Westwood (TCPW) is a sender-side modification of the TCP congestion window algorithm that improves upon the performance of TCP Reno in wired as well as wireless networks. In fact, TCPW performance is not very sensitive to random errors, while... [14 Jan 2008]
Performance Evaluation of Westwood+ TCP Congestion Control
White Paper This estimate is used to adaptively decrease the congestion window and slow start threshold after a congestion episode. Westwood+ TCP is a sender-side only modification of the classic Tahoe/Reno TCP that has been recently proposed to improve... [14 Jan 2008]
A Positive Systems Model of TCP-Like Congestion Control: Asymptotic Results
White Paper This paper studies communication networks that employ drop-tail queueing and Additive-Increase Multiplicative-Decrease (AIMD) congestion control algorithms. It shows that the theory of nonnegative matrices may be employed to model such networks. [14 Jan 2008]
Modelling TCP Congestion Control Dynamics in Drop-Tail Environments
White Paper This paper studies communication networks that employ drop-tail queueing and Additive-Increase Multiplicative-Decrease (AIMD) congestion control algorithms. It shows that the theory of nonnegative matrices may be employed to model such networks. [14 Jan 2008]
TCP Flow Control Based on an Instantaneous Model
White Paper With TCP the network congestion is controlled by adjusting the transmission rate through congestion window (cwnd). The dynamics of TCP can be modelled by switching between the two sub-dynamic models: dynamics of congestion avoidance and dynamics of... [14 Jan 2008]
Performance Impact of Interaction of ARQ Error Control in Layer 2 and Handover Control in Layer 3 on Wireless TCP
White Paper In wireless environment, TCP suffers from significant performance degradation due to bit errors on wireless link and handover because it responds to all packet losses by invoking congestion control even though packet losses are not related to... [14 Jan 2008]
On Modeling Feedback Congestion Control Mechanism of TCP Using Fluid Flow Approximation and Queueing Theory
White Paper The Internet uses a window-based congestion control mechanism in TCP (Transmission Control Protocol). This paper explicitly models the interaction between the congestion control mechanism of TCP and the network as a feedback system. [14 Jan 2008]
TCP Rate Control Using Active ECN Mechanism With RTT-Based Marking Probability
White Paper The end-to-end TCP congestion control based on a window flow control mechanism can cause unfairness among multiple TCP connections with different RTT (Round Trip Time), due to its non-uniform increase of the rate. [14 Jan 2008]
A HighSpeed TCP Study: Characteristics and Deployment Issues
White Paper The current congestion control mechanism used in TCP has difficulty reaching full utilization on high speed links, particularly on wide-area connections. HighSpeed TCP was recently proposed as a modification of TCP's congestion control mechanism to... [14 Jan 2008]
Steady State and Transient State Behaviors Analyses of TCP Connections Considering Interactions Between TCP Connections and Network
White Paper The Internet uses a window-based congestion control mechanism in TCP (Transmission Control Protocol). This paper explicitly models the interaction between the congestion control mechanism of TCP and the network as a feedback system. [14 Jan 2008]
TCP: Errors Versus Congestion Losses I Alternative Bandwidth Estimation
White Paper This paper first describes the interesting parts of TCP protocol when talking about congestion control and bandwidth estimation. TCP is tuned to perform well in traditional networks where packet loss occurs mostly because of congestion. [14 Jan 2008]
A Flow Control Scheme Based on Buffer State for Wireless TCP
White Paper Reliable transport protocols such as TCP (Transmission Control Protocol) are tuned to perform well in traditional networks where packet losses occur mostly because of congestion. BSF uses the buffer state of base station as the criterion to detect... [14 Jan 2008]
