Investigation of Ethernet Switches Behavior in Presence of Contending Flows at Very High-Speed
White Paper First, the behavior of a range of Ethernet switches when two long lived connections compete to the same output port is investigated. This paper examines the interactions between high speed Ethernet switches and TCP in high bandwidth delay product... [08 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 recovery, and gross unfairness between competing flows. [03 Jul 2008]
A Rate Controller for Long-Lived TCP Flows
White Paper In this paper a new mechanism for providing an assured rate to a long-lived TCP flow is proposed. The mechanism is called TCP rate controller (TRC) and operates as a traffic conditioner at the edge of a network. [14 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 for, a common resource, typically a link and its... [14 Jan 2008]
TCP Model for Short Lived Flows
White Paper Among the TCP flows, a large majority are short lived flows with the average and the median lengths no larger than 10 KB. These figures highlight the importance of understanding the behavior of short lived TCP flows. [14 Jan 2008]
TCP Throughput Analysis Under Transmission Error and Congestion Losses
White Paper This paper analyzes the performance of a large population of long lived TCP flows experiencing random packet losses due to both random transmission errors and congestion created by the sharing of a common tail drop bottleneck router. [14 Jan 2008]
Interaction of TCP Flows as Billiards
White Paper The aim of this paper is to analyze the performance of a large number of long lived TCP controlled flows sharing many routers (or links), from the knowledge of the network parameters (capacity, buffer size, topology) and of the characteristics of... [14 Jan 2008]
An Implementation of a Service Class Providing Assured TCP Rates Within the AQUILA Framework
White Paper This paper investigates an attempt to establish a QoS class that supports long-lived, bulk-data TCP flows that require a minimum rate from the network. The approach is based on a model for TCP flows subject to token bucket marking at the network... [14 Jan 2008]
TCP Smart-Framing: Using Smart Segments to Enhance the Performance of TCP
White Paper This paper proposes an enhancement to the TCP protocol, called TCP Smart-Framing (TCP-SF), that enables the Fast Recovery algorithm for short lived flows, as most of the current Internet traffic is. Without modifying the TCP congestion control... [14 Jan 2008]
Improving the Performance of TCP on Guaranteed Bandwidth Connections
White Paper Second, short-lived TCP connections have become more and more important in the Internet. Short-lived connections are needed in transaction-oriented network applications and client-server scenarios; a typical example is the common use of the World... [14 Jan 2008]
Performance Evaluation of a New Adaptive Packet Marking Scheme for TCP Over DiffServ Networks
White Paper The proposed marking scheme is most efficient when applied to a scenario composed of all long-lived flows. This paper presents an extensive performance evaluation of a new adaptive packet marking scheme, applied to a traffic scenario composed of... [14 Jan 2008]
TCP Smart Framing: A Segmentation Algorithm to Reduce TCP Latency
White Paper This choice is motivated by real traffic measurements, which indicate that today's traffic is populated by short-lived flows, whose only means to recover from a packet loss is by triggering a Retransmission Timeout. [14 Jan 2008]
Impact of 802.11e EDCA on Mixed TCP-Based Applications
White Paper This paper evaluates the impact of EDCA on TCP application traffic consisting of both long and short-lived TCP flows, through ns-2 simulations. Recent work has shown that the widely-deployed IEEE 802.11 MAC Distributed Coordination Function (DCF... [08 Jan 2008]
Analysis of the Competition Between Wired, DSL and Wireless TCP Flows in an Access Network
White Paper This paper analyzes the performance of a large population composed of several classes of long lived TCP flows experiencing packet losses due to random transmission errors and to congestion created by the sharing of a common tail-drop or AQM... [26 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 develop an extensive stochastic model which... [19 Dec 2007]
