Modeling and Performance Analysis of Dynamic Random Early Detection (DRED) Gateway for Congestion Avoidance
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 ...
متن کاملLow pass filter/over drop avoidance (LPF/ODA): an algorithm to improve the response time of RED gateways
The low pass filter (LPF) algorithm, which is used to calculate the average queue length in the random early detection (RED) algorithm, results in a poor response time when RED recovers from congestion. In this paper, we propose a new algorithm, called low pass filter/over drop avoidance (LPF/ODA), to improve the response time of RED. LPF/ODA is based on reducing the time required by RED to rec...
متن کاملPacket Loss of Congestion Control Using Early Random in Network
Congestion control of a variable bit-rate data stream crossing the Internet is crucial to ensuring the quality of the received data. This paper discusses the use of link-sharing mechanisms in packet networks and presents algorithms for hierarchical link-sharing. Hierarchical linksharing allows multiple agencies, protocol families, or traffic types to share the bandwidth on a link in a controlle...
متن کاملRandom Early Detection Gateways for Gongestion Avoidance
The paper presents an active queue management technique of preventing congestion in packet-switch networks called Random Early Detection (RED) gateways. RED is based on the observation that congestion can most accurately be understood at the gateway, since it can distinguish high propagation delay from high delay brought on by increasing queue lengths. Therefore, they suggest that congestion de...
متن کاملRefined Design of Random Early Detection Gateways
Random Early Detection (RED) was proposed as an active gateway queue-management mechanism. This paper proposes to alter the RED design guideline that unconditionally allows transient congestion, and evaluates its impacts. This unconditional allowance of transient congestion is shown to be harmful when the queue is near full, because it causes buffer overflow at a gateway. Buffer overflow at a g...
