Detailed Description

Helper class to simplify writing basic simulation scenarios.

The following code with scenario helper creates a 3-node topology, with manual routes between nodes and 2 applications, installed on first and last node of the topology:

ScenarioHelper helper;
helper.createTopology({
    {"1", "2"},
    {"2", "3"}
  });

helper.addRoutes({
    {"1", "2", "/prefix", 1},
    {"2", "3", "/prefix", 1}
  });

helper.addApps({
    {"1", "ns3::ndn::ConsumerCbr",
        {{"Prefix", "/prefix"}, {"Frequency", "1"}},
        "0s", "100s"},
    {"3", "ns3::ndn::Producer",
        {{"Prefix", "/prefix"}, {"PayloadSize", "1024"}},
        "0s", "100s"}
  });
