Rate Based Congestion Control Over High Bandwidth/Delay Links
White Paper Such a rate based congestion control is TCP friendly and it has better bandwidth utilization than TCP. As the network bandwidth and delay increase, traditional dominant transfer protocols on the Internet like TCP have shown inefficiency and... [11 Jul 2008]
End-to-End Available Bandwidth: Measurement Methodology, Dynamics, and Relation With TCP Throughput
White Paper Pathload is nonintrusive, meaning that it does not cause significant increases in the network utilization, delays, or losses. The available bandwidth (avail-bw) in a network path is of major importance in congestion control, streaming applications... [10 Jul 2008]
Achieving High Throughput in Low Multiplexed, High Bandwidth, High Delay Environments
White Paper Coupled with an AQM scheme such as RED, TCP sources achieve high utilization at a bottleneck router, but at the cost of fairness. The paper introduces a lightweight AQM mechanism that ensures fairness while still providing high utilization to the... [08 Jul 2008]
Improving XCP to Achieve Max-Min Fair Bandwidth Allocation
White Paper Extensive simulations show that iXCP overcomes the weakness of XCP, and achieves efficient and fair bandwidth utilization in both single- and multi-bottleneck environments. In a multi-bottleneck environment, XCP may achieve as low as 80... [08 Jul 2008]
A TCP Agent Scheme Based on Active Buffer Control to Support Lossless Handover in Broadband Wireless Networks
White Paper So, high utilization is achievable even with frequent handovers. This paper presents an active buffer control based TCP agent scheme that can overcome TCP performance degradation caused by handovers in broadband wireless networks. [03 Jul 2008]
The Role of Buffer Management in Controlling the Effects of Congestion over 10 GbE Links
White Paper DBP-sized buffers, together with RED congestion avoidance, can be used to optimize the utilization of congested links by TCP applications. This white paper describes the rationale for providing switch/routers with port buffers that are scaled to... [08 Feb 2008]
Fairness Analysis of TCP/IP
White Paper This permits to evaluate the improvement in fairness and utilization brought by the deployment of active buffers. Bandwidth sharing between multiple TCP connections has been studied under the assumption that the windows of the different connections... [15 Jan 2008]
Performance Analysis and Improvement of HighSpeed TCP With TailDrop/RED Routers
White Paper Continuous and explosive growth of the Internet has shown that current TCP mechanisms cannot achieve efficient utilization of networks with large bandwidth-delay products. To address this problem, the paper proposes an enhanced transport-layer... [15 Jan 2008]
On the Transient Behavior of TCP Vegas
White Paper Research has shown that TCP Vegas performs better than TCP Reno with respect to overall network utilization, stability, fairness, throughput, packet loss, and burstiness. This paper analyzes and improve the transient behavior of TCP Vegas, an... [15 Jan 2008]
Jointly Coordinating ECN and TCP for Rapid Adaptation to Varying Bandwidth
White Paper Moreover, the milder backoff policy of ECN-mod also makes the link utilization less dependent on the exact values of the parameters in the router marking function. By making routers mark packets in a much more aggressive manner, the authors are... [15 Jan 2008]
Inline Path Characteristic Estimation to Improve TCP Performance in High Bandwidth-Delay Networks
White Paper The results show that TCPW BBE alone is more efficient than Reno in that it provides much higher utilization of link bandwidth, while TCPW BBE is also shown to be friendly when co-existing with Reno. This paper presents a measurement study of TCPW... [27 Dec 2007]
Dealing With Sudden Bandwidth Changes in TCP
White Paper Consequently, it might suffer from packet losses in burst upon sudden decrements of bandwidth and under-utilization upon sudden increments of bandwidth. This paper proposes a novel technique to deal with sudden bandwidth changes in TCP. [27 Dec 2007]
SaTPEP: A TCP Performance Enhancing Proxy for Satellite Links
White Paper SaTPEP monitors the satellite link utilization, and assigns to connections window values that reflect the available bandwidth. Satellite link characteristics cause reduced performance in TCP data transfers. [27 Dec 2007]
TCP-Vegas Slow Start Performance in Large Bandwidth Delay Network
White Paper According to a number of previous studies, it is said to fairly treat connections with different propagation delays and avoid under-utilization even with a buffer that is independent of the bandwidth delay product. [21 Dec 2007]
Testing TCP Westwood+ Over Transatlantic Links at 10 Gigabit/Second Rate
White Paper Introduction of 10 Gigabit Routers and 10 Gigabit Ethernet cards makes of great interest the issue of designing and testing new protocols capable of efficient utilization of 10 gigabit Internet paths. [21 Dec 2007]
