Several gateway-based congestion control mechanisms have been proposed to support an end-to-end congestion control mechanism of TCP (Transmission Control Protocol). One of promising gateway-based congestion control mechanisms is a RED (Random Early Detection) gateway. Although effectiveness of the RED gateway is fully dependent on a choice of control parameters, it has not been fully investigat...

Explicit Congestion Notification (ECN) and Active Queue Management Schemes such as Random Early Detection (RED), Adaptive Random Early Detection (ARED) and BLUE queues have been proposed for TCP/IP networks to compensate network congestion. However, using ECN requires that ECN be supported by both TCP senders and receivers. This paper presents a novel AQM modification called Receiver-Window Mod...

One of the most prominent congestion avoidance schemes in the Internet architecture is the Random Early Detection (RED) algorithm. Several modifications and enhancements have been made to the original RED so as to make it more responsive to congestion avoidance at the gateways. In this paper, we introduced the Dynamic Random Early Detection (DRED) model, which uses a newly introduced parameter ...

In this work, we investigate mechanisms for Internet congestion control in general, and Random Early Detection (RED) in particular. We first study the current proposals for RED implementation and identify several structural problems such as producing large traffic oscillations and introducing unnecessary overhead in the fast path forwarding. We model RED as a feedback control system and we disc...

The paper describes a Multicasting network using PIM-DM (Protocol Independent MulticastDense Mode) with two queuing algorithms Drop Tail and Random Early Detection (RED). A simulation environment is created in NS2 to analyse and contrast Drop Tail and RED for queue management on basis of drop out data packets in network. The experiment indicates better performance of RED by 13.7375% on the basi...

Interaction between Transmission Control Protocol (TCP) and Random Early Detection (RED) gateways can be captured using dynamical models. The communication network is viewed as a discrete-time feedback control system where TCP adjusts its window size depending on whether or not it has detected a packet loss during the previous round trip time (RTT) interval. In this article, we describe a discr...

Due to the rapid development in computer networks, congestion becomes a critical issue. Congestion usually occurs when the connection demands on network resources, i.e. buffer spaces, exceed the available ones. We propose in this paper a new discrete-time queueing network analytical model based on dynamic random early drop (DRED) algorithm to control the congestion in early stages. We apply our...

This paper proposes an adaptive queue management scheme (adaptive RED) to improve Random Early Detection (RED) on restraining non-responsive flows. Due to a lack of flow control mechanism, non-responsive flows can starve responsive flows for buffer and bandwidth at the gateway. In order to solve the disproportionate resource problem, RED framework is modified in this way: on detecting when the ...

Abstract— Recently TCP/RED networks are shown to exhibit a rich set of nonlinear behaviors, leading to instabilities. In order to address some of these issues Floyd et al. have proposed an adaptive version of RED, named ARED. In this paper we analytically demonstrate that ARED has some desirable properties compared to RED. First, we show that the stability of the ARED does not depend on the net...
