Detailed Description

Receive and consume traffic generated to an IP address and port.

This application was written to complement OnOffApplication, but it is more general so a PacketSink name was selected. Functionally it is important to use in multicast situations, so that reception of the layer-2 multicast frames of interest are enabled, but it is also useful for unicast as an example of how you can write something simple to receive packets at the application layer. Also, if an IP stack generates ICMP Port Unreachable errors, receiving applications will be needed.

The constructor specifies the Address (IP address and port) and the transport protocol to use. A virtual Receive () method is installed as a callback on the receiving socket. By default, when logging is enabled, it prints out the size of packets and their address. A tracing source to Receive() is also available.

Config Paths

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

Member Function Documentation

void ns3::PacketSink::DoDispose ( void  )
protectedvirtual

Destructor implementation.

This method is called by 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.
