TCP Performance in Wireless Access With Adaptive Modulation and Coding
White Paper We study a wireless access system with adaptive modulation and coding (AMC) at the physical layer, finite-length queuing at the data link layer and a TCP protocol at the transport layer. We analyze the end-to-end TCP performance via a fixed-point... [14 Jan 2008]
Adaptive Low Priority Packet Marking for Better TCP Performance
White Paper Low priority packets are marked according to an adaptive marking algorithm. This paper proposes a packet marking scheme for TCP traffic. Unlike previous literature work, in the scheme the majority of TCP packets are transmitted as high priority. [14 Jan 2008]
Performance Evaluation of a New Adaptive Packet Marking Scheme for TCP Over DiffServ Networks
White Paper This paper presents an extensive performance evaluation of a new adaptive packet marking scheme, applied to a traffic scenario composed of TCP flows with different length. As a consequence, packet marking schemes can be devised to differentiate... [14 Jan 2008]
TCP-Africa: An Adaptive and Fair Rapid Increase Rule for Scalable TCP
White Paper The default transport control protocol for best effort data traffic is currently TCP, which does not scale well to 100Mbps and higher networks over long distances. In congestion avoidance TCP is not swift enough to fully utilize resources over... [14 Jan 2008]
TCP Performance Over End-to-End Rate Control and Stochastic Available Capacity
White Paper Motivated by TCP over end-to-end ABR, this paper studies the performance of adaptive window congestion control, when it operates over an explicit feedback rate-control mechanism, in a situation in which the bandwidth available to the elastic... [14 Jan 2008]
Assembling TCP/IP Packets in Optical Burst Switched Networks
White Paper The results show that the performance of the proposed Adaptive-Assembly-Period (AAP) algorithm is better than that of the Min-BurstLength-Max-Assembly-Period (MBMAP) algorithm and the Fixed-Assembly-Period (FAP) algorithm in terms of goodput and... [14 Jan 2008]
A New Three Color Marker for TCP Flows
White Paper This paper presents an extensive performance evaluation of a new adaptive packet marking scheme, which relies on three different service classes, provided by the DiffServ network. As a consequence, packet marking schemes can be devised to... [14 Jan 2008]
Performance Analysis and Improvement of HighSpeed TCP With TailDrop/RED Routers
White Paper Furthermore, it is observed that the performance of gHSTCP is limited by both TailDrop and RED/ARED routers, thus it develops a modified adaptive RED called gARED to address the problem of simultaneous packet drops among multiple flows. [14 Jan 2008]
Load Balancing for Parallel Forwarding
White Paper A pure hash-based system, however, cannot balance processor load in the face of highly skewed flow-size distributions in the Internet; usually, adaptive methods are needed. Scheduling schemes that operate at the packet level, e.g.round-robin... [14 Jan 2008]
Performance Evaluation of Westwood+ TCP Congestion Control
White Paper In this way Westwood+ TCP substitutes the classic multiplicative decrease paradigm with the adaptive decrease paradigm. Westwood+ TCP is a sender-side only modification of the classic Tahoe/Reno TCP that has been recently proposed to improve... [14 Jan 2008]
TCP Adaptive RTO to Improve TCP Performance in Mobile Ad Hoc Networks
White Paper This paper proposes a new mechanism called TCP Adaptive RTO (TCP AR) that improves TCP performance in mobile ad hoc network s. With the assumption that all packet losses are due to congestion, TCP performs poorly in such an environment. [26 Dec 2007]
Cross-Layer Analysis of TCP Performance in a 4G System
White Paper The aspects investigated are the impact of channel prediction errors, channel scheduling, delay, and adaptive modulation switch level, on TCP performance. This paper presents results from an experimental study of TCP in a wireless 4G evaluation... [26 Dec 2007]
An Analytical Model of a New Packet Marking Algorithm for TCP Flows
White Paper This paper presents an analytical model for an adaptive packet marking scheme proposed in the previous work. As a consequence, packet marking schemes can be devised to differentiate packets belonging to a same TCP flow, with the goal of improving... [26 Dec 2007]
Testing TCP Westwood+ Over Transatlantic Links at 10 Gigabit/Second Rate
White Paper The main feature of Westwood+ TCP is its adaptive setting of the control windows after a congestion episode obtained by estimating the bandwidth available along the connection path. This paper reports a first investigation of the performance of... [20 Dec 2007]
Smartacking: Improving TCP Performance From the Receiving End
White Paper This paper presents smartacking, a technique that improves performance of Transmission Control Protocol (TCP) via adaptive generation of acknowledgments (ACKs) at the receiver. When the bottleneck link is underutilized, the receiver transmits an... [19 Dec 2007]
