tcp - ip flows for connections

Passive Estimation of TCP Round-Trip Times

White Paper The first technique is applicable to TCP caller-to-callee flows, and it is based on the 3-way handshake messages. The second technique is applicable to callee-to-caller flows, when the... [03 Jul 2008]

GPRSWeb: Optimizing the Web for GPRS Links

White Paper The paper examines why certain GPRS network characteristics interact badly with TCP to yield problems such as: link under-utilization for short-lived flows, ACK compression, poor loss... [03 Jul 2008]

Improving the Performance of TCP on Guaranteed Bandwidth Connections

White Paper The congestion control mechanisms like slow start and congestion avoidance have to be revised in the context of guaranteed services, where no congestions occur for special flows. Nevertheless,... [15 Jan 2008]

Fixed-Point Approximations for TCP Performance Over Bandwidth on Demand GEO Satellite Links

White Paper This paper investigates the use of fixed-point methods for predicting the performance of multiple TCP flows sharing geostationary satellite links. The problem formulation is general in... [15 Jan 2008]

Queueing Network Model of Short-Lived TCP Flows With Mixed Wired and Wireless Access Links

White Paper This paper presents an analytical model, based on a Fixed Point Approximation (FPA) solution, that can be used to derive the performance of different sets of TCP connections that share, and compete... [15 Jan 2008]

TCP Testing - Preventing Global Internet Warming

White Paper Testing multiple flows using applications (rsync and ftp) shows some unfairness exists when the bottleneck queue is large; but the new algorithms are no more unfair than standard TCP. The Transmission... [27 Dec 2007]

A Stochastic Model for Short-Lived TCP Flows

White Paper This paper proposes a new model for the slow-start phase based on the discrete evolutions on the congestion window, and this slow-start model is used together with the improved TCP steady-state model to... [20 Dec 2007]

On Individual and Aggregate TCP Performance

White Paper The TCP behavior under many competing TCP flows has not been sufficiently explored. This paper uses extensive simulations to investigate the individual and aggregate TCP... [20 Dec 2007]

Modelling TCP Flows Over an 802.11 Wireless LAN

White Paper This paper presents an analysis of the throughput of TCP flows transmitted over IEEE 802.11 wireless LAN connections, for the case when TCP flow control... [06 Dec 2007]

The Effects of Systemic Packet Loss on Aggregate TCP Flows

White Paper In the presence of congestion related losses, parallel flows steal bandwidth from other single stream flows. The use of parallel TCP connections to increase throughput... [06 Dec 2007]

Experimental Analysis of the Impact of Peer-to-Peer Applications on Traffic in Commercial IP Networks

White Paper When analyzing the bit rate created by long flows, it turns out that the TCP connections due to peer-to-peer applications have a rather small bit rate and that there is no evidence... [06 Dec 2007]

A Queueing Model for HTTP Traffic Over IEEE 802.11 WLANs

White Paper This result is then used to develop a queueing model, which is used to determine the mean session delay in presence of short-lived flows. The paper first considers the interaction of TCP with the IEEE... [24 May 2006]

An Integrated Model for the Latency and Steady State Throughput of TCP Connections

White Paper In this paper, we we propose an accurate model for estimating the transfer times of TCP flows of arbitrary size. Thus the underlying assumptions made by steady-state models cease to hold... [25 Feb 2004]
