random early detection (red) is one of the most commonly used active queue management (aqm) algorithms that is recommended by ietf for deployment in the network. although red provides low average queuing delay and high throughput at the same time, but effectiveness of red is highly sensitive to the red parameters setting. as network condition varies largely, setting red's parameters with fixed ...

active queue management (aqm) plays an important role in the internet congestion control. it tries to enhance congestion control, and to achieve tradeoff between bottleneck utilization and delay. random early detection (red) is the most popular active queue management algorithm that has been implemented in the in internet routers and is trying to supply low delay and low packet loss. red algori...

In this paper, we present a mechanism called DWRED (Dynamic Weighted RED) that uses communicating agents in a Multi-Agents Systems to enhance the Random Early Detection (RED) congestion management algorithm, by providing service for multiple classes of traffic as well as cooperation between the network nodes to dynamically modify the running algorithm’s parameters in response to network congest...

This paper introduces a technique for applying packet arrival rate based queue management to class based scheduling algorithms. This enables a DiffServ architecture with very low packet latency, loss, and high link utilisation. Simulation results demonstrate that the proposed technique outperforms the current weighted random early drop (WRED) and weighted fair queue (WFQ) architecture.

あらまし 近年、エンド–エンド間で動作する TCPの輻輳制御機構を補助し、ルータにおいて積極的に輻輳制御を行 う、アクティブキュー管理機構が注目を浴びている。アクティブキュー管理機構には制御パラメータが存在するが、そ の有効性はこれらの制御パラメータの設定に依存する。そのため、アクティブキュー管理機構の制御パラメータ設定 方法に関しては、これまでさまざまな研究が行われてきた。しかし、そのほとんどは、少数のシミュレーション結果か ら、制御パラメータがアクティブキュー管理機構の性能に与える影響を調べているにすぎない。そこで本稿では、多 変量解析手法を用いることにより、膨大な数のシミュレーション結果を統計的に解析し、アクティブキュー管理機構の 制御パラメータが、その性能にどのような影響を与えるかを定量的に明らかにする。本稿では、代表的なアクティブ キュー管理機構である RED (Rando...
