Can Shortest-Path Routing and TCP Maximize Utility
White Paper TCP-AQM protocol can be interpreted as distributed primal-dual algorithms over the Internet to maximize aggregate utility. This paper studies whether TCP-AQM together with shortest-path routing can... [11 Sep 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... [08 Jul 2008]
Fuzzy Logic Congestion Control in TCP/IP Best-Effort Networks
White Paper This paper presents a new Active Queue Management (AQM) scheme -Fuzzy Explicit Marking (FEM)- supporting explicit congestion notification (ECN), to provide congestion control in TCP/IP... [15 Jan 2008]
Global Stability Analysis of a TCP/AQM Protocol for Arbitrary Networks With Delay
White Paper This paper investigates global stability of Fast AQM Scalable TCP (FAST), a network congestion control scheme for the Internet modelled by a nonlinear delay differential equation with heterogeneous delays. [15 Jan 2008]
TCP Westwood and Easy RED to Improve Fairness in High-Speed Networks
White Paper Moreover, we propose EASY RED, which is a simple Active Queue Management (AQM) scheme that improves fair sharing of network capacity especially over high-speed networks. TCP Westwood (TCPW) is a sender-side only... [15 Jan 2008]
On Transient Behavior Analysis of Random Early Detection Gateway Using a Control Theoretic Approach
White Paper AQM (Active Queue Management) mechanisms support the end-to-end congestion control mechanism of TCP (Transmission Control Protocol). Several AQM mechanisms have been recently proposed... [15 Jan 2008]
Congestion Control for TCP/AQM Networks Using State Predictive Control
White Paper The purpose of this paper is to design congestion controllers for TCP/AQM networks using state predictive control and illustrate effectiveness of designed congestion controllers via... [09 Jan 2008]
Analyzing the Receiver Window Modification Scheme of TCP Queues
White Paper Explicit Congestion Notification (ECN) and Active Queue Management (AQM) Schemes such as Random Early Detection (RED), Adaptive Random Early Detection (ARED) and BLUE queues have been proposed for TCP/IP... [27 Dec 2007]
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... [27 Dec 2007]
Time-Driven Early Discard (TED) to Improve the Fairness of TCP Congestion Control
White Paper This paper proposes a novel adaptive AQM (advanced queue management) approach called Time-Driven Early Discard (TED). The basic underlying idea is to set a deadline on packet service time in routers, beyond which packets... [27 Dec 2007]
Analysis of TCP-AQM Interaction Via Periodic Optimization and Linear Programming: The Case of Sigmoidal Utility Function
White Paper This paper investigates the interaction between Transmission Control Protocol (TCP) and an Active Queue Management (AQM) router, that are designed to control congestion in the Internet. TCP controls the... [20 Dec 2007]
A Novel Fuzzy Logic Controller (FLC) for Shortening the TCP Channel Roundtrip Time by Eliminating User Buffer Overflow Adaptively
White Paper The FLC contributes to prevent the AQM resources dished out at the system level from being wasted, shorten the service RoundTrip Time (RTT) by reducing retransmission, and alleviate network congestion in... [20 Dec 2007]
Using Steady-State TCP Behavior for Proactive Queue Management
White Paper This is in contrast to traditional Active Queue Management (AQM) schemes, where incipient congestion is detected early and then reacted to. It shows how routers can use flow parameters and the knowledge... [20 Dec 2007]
LRED: A Robust and Responsive AQM Algorithm Using Packet Loss Ratio Measurement
White Paper Active Queue Management (AQM) is an effective means to enhance congestion control, and to achieve trade-off between link utilization and delay. Recent proposals based on analytical TCP control and... [06 Dec 2007]
TCP Throughput and Timeout - Steady State and Time-Varying Dynamics
White Paper Active queue management (AQM) is an important application of these dynamic models. However, recent work has shown that AQM provides little performance benefit over drop-tail queueing for HTTP traffic,... [06 Dec 2007]
