Implementation of Refined Adaptive RED (RARED) algorithm in ns-3

Course Code: CS822

Assignment: #GP6

Overview

Refined Adaptive RED (RARED) [1] is an extension of ARED [2]. It inherits all the properties of ARED but with a minor improvement in adaptive setting of Pmax. This repository contains an implementation of RARED in ns-3 [3].

Simulating RARED

To simulate RARED algorithm, the attribute RARED must be set to true, as shown below:

Config::SetDefault ("ns3::RedQueueDisc::RARED", BooleanValue (true));

RARED example

An example program for RARED has been provided in

src/traffic-control/examples/red-vs-rared.cc

and should be executed as

./waf --run "red-vs-rared --queueDiscType=RARED"
