void EnableAsciiAll(std::string prefix)
Enable ascii trace output on each device (which is of the appropriate type) in the set of all nodes c...
bool tracing
Flag to enable/disable generation of tracing files.
Every class exported by the ns3 library is enclosed in the ns3 namespace.
A helper class to make life easier while doing simple IPv4 address assignment in scripts.
void SetDeviceAttribute(std::string name, const AttributeValue &value)
Set an attribute value to be propagated to each NetDevice created by the helper.
void SetChannelAttribute(std::string name, const AttributeValue &value)
Set an attribute value to be propagated to each Channel created by the helper.
Create an application which sends a UDP packet and waits for an echo of this packet.
@ LOG_LEVEL_ALL
Print everything.
void LogComponentEnable(char const *name, enum LogLevel level)
Enable the logging output associated with that log component.
NetDeviceContainer Install(NodeContainer c)

void Create(uint32_t n)
Create n nodes and append pointers to them to the end of this NodeContainer.
void Add(NodeContainer other)
Append the contents of another NodeContainer to the end of this container.
Helper class that adds Nix-vector routing to nodes.
static void PopulateRoutingTables(void)
Build a routing database and initialize the routing tables of the nodes in the simulation.
static void Stop(void)
