|

* This class provides an internet four-tuple (source and destination ports
|
|
* and addresses). These are used in the ns3::Ipv4EndPointDemux as targets
|
|
* of lookups. The class also has a callback for notification to higher
|
|
* layers that a packet from a lower layer was received. In the ns3
|
|
* internet-stack, these notifications are automatically registered to be
|
|
* received by the corresponding socket.
