Detailed Description

A Udp Echo server.

Every packet received is sent back.

Config Paths

ns3::UdpEchoServer is accessible through the following paths with Config::Set and Config::Connect:

• /NodeList/[i]/ApplicationList/[i]/$ns3::UdpEchoServer

Attributes

Member Function Documentation

void ns3::UdpEchoServer::DoDispose ( void  )

protectedvirtual

This method is called by Object::Dispose or by the object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overriden version of this method and chain up to their parent's implementation once they are done. i.e., for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose method.

It is safe to call GetObject from within this method.

Reimplemented from ns3::Application.

Definition at line 67 of file udp-echo-server.cc.

References ns3::Application::DoDispose(), and NS_LOG_FUNCTION.

void ns3::UdpEchoServer::StartApplication ( void  )

privatevirtual

Application specific startup code.

The StartApplication method is called at the start time specified by Start This method should be overridden by all or most application subclasses.

Reimplemented from ns3::Application.

Definition at line 74 of file udp-echo-server.cc.

References ns3::Socket::Bind(), ns3::Socket::CreateSocket(), ns3::Ipv4Address::GetAny(), ns3::Ipv6Address::GetAny(), ns3::Application::GetNode(), ns3::TypeId::LookupByName(), ns3::MakeCallback(), NS_FATAL_ERROR, NS_LOG_FUNCTION, and ns3::Socket::SetRecvCallback().

void ns3::UdpEchoServer::StopApplication ( void  )

privatevirtual

Application specific shutdown code.

The StopApplication method is called at the stop time specified by Stop This method should be overridden by all or most application subclasses.

Reimplemented from ns3::Application.

Definition at line 125 of file udp-echo-server.cc.
