I tried to limit the number of contents to 100 (50 for Interest1 and 50 for
Interest2) like this:
ndn::AppHelper consumerHelper("ns3::ndn::ConsumerZipfMandelbrot");
consumerHelper.SetAttribute("Frequency", DoubleValue(10.0));
consumerHelper.SetAttribute("NumberOfContents", StringValue("50"));
consumerHelper.SetPrefix("/Interest1");
consumerHelper.Install(nodes.Get(0));
consumerHelper.Install(nodes.Get(3));
consumerHelper.Install(nodes.Get(4));
ndn::AppHelper consumerHelper2("ns3::ndn::ConsumerZipfMandelbrot");
consumerHelper2.SetAttribute("Frequency", DoubleValue(10.0));
consumerHelper2.SetAttribute("NumberOfContents", StringValue("50"));
consumerHelper2.SetPrefix("/Interest2");
consumerHelper2.Install(nodes.Get(6));
consumerHelper2.Install(nodes.Get(8));
consumerHelper2.Install(nodes.Get(5));
I expected to find exactly 100 content in the log file, but I found 88 for
Interest1 and 48 for Interest2.
I wonder what the reason for this is??
My best regards,
Zakaria
