Subject: [Codel] ns-3.15 simulations using CoDel
Date: Sun, 30 Sep 2012 18:23:25 +0200	[thread overview]
Message-ID: <506871FD.5070000@eecs.qmul.ac.uk> (raw)

Hi all,

I am trying to run CoDel simulations using ns-3.15 and Andrew McGregor's 
CoDel patch available at http://www.bufferbloat.net/projects/codel/wiki.

For some reason, I am getting all delay and queue length results using 
CoDel equal to the results using DropTail. Can anyone indicate reasons 
for such performance? I am generating UDP packets using On-Off 
applications set as a Poisson Traffic generator on 10 nodes aggregated 
on a common node set as the bottleneck node. Below is the part of the 
code which implements CoDel.

   Config::SetDefault ("ns3::CoDelQueue::Mode", StringValue ("Packets"));
   Config::SetDefault ("ns3::CoDelQueue::MaxPackets", UintegerValue 
(10000));
   Config::SetDefault ("ns3::CoDelQueue::Interval", StringValue ("0.8ms"));
   Config::SetDefault ("ns3::CoDelQueue::Target", StringValue ("0.2ms"));
   Config::SetDefault ("ns3::CoDelQueue::MinBytes", UintegerValue(1500));

   CsmaHelper csma;
   csma.SetChannelAttribute ("DataRate", StringValue(LinkRate));
   csma.SetChannelAttribute ("Delay", TimeValue (Seconds (0)));
   csma.SetQueue ("ns3::CoDelQueue");

Thanks a lot for your help and best regards,
Mark
