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"}
  });

Member Function Documentation

void ns3::ndn::ScenarioHelper::createTopology	(	std::initializer_list< std::initializer_list< std::string >>	topology,
		bool	shouldInstallNdnStack = true
	)

Create topology.

Exceptions

std::logic_error

if createTopology is called more than once

Example:

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

void ns3::ndn::ScenarioHelper::addRoutes

(

std::initializer_list< RouteInfo >

routes

)

Create routes between topology nodes.

Exceptions

std::invalid_argument

if the nodes or links between nodes do not exist

Example:

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

void ns3::ndn::ScenarioHelper::addApps

(

std::initializer_list< AppInfo >

apps

)

Create and install application on nodes.

Exceptions

std::invalid_argument

if the nodes or links between nodes do not exist

Example:

helper.addApps({
    {"1", "ns3::ndn::ConsumerCbr",
        {{"Prefix", "/prefix"}, {"Frequency", "1"}},
        "0s", "100s"},
