    34  * \brief A representation of an internet endpoint/connection

    35  *

    36  * This class provides an internet four-tuple (source and destination ports 

    37  * and addresses).  These are used in the ns3::Ipv4EndPointDemux as targets

    38  * of lookups.  The class also has a callback for notification to higher

    39  * layers that a packet from a lower layer was received.  In the ns3

    40  * internet-stack, these notifications are automatically registered to be

    41  * received by the corresponding socket.
