* OPacket - A frame on the wire
*======================================================================================*/
/** @brief A class representing a data frame on the wire.
*
* The whole family of the packet classes are used when capturing frames from a network.
* Most standard network protocols in use share a common architecture, which mostly is
* a packet header and then the packet payload. In layered architectures, each lower layer
* encapsulates data from its upper layer - that is it
* treats the data from its upper layer as payload and prepends an own header to the packet,
* which - again - is treated as the payload for the layer below. The figure below is an
* example for how such a data frame is composed out of packets, e.g. when sending a mail.
*
* <pre>
* | User Data | == Mail Data
* | SMTP Header | User Data | == SMTP
* | TCP Header | SMTP Header | User Data | == TCP
* | IP Header | TCP Header | SMTP Header | User Data | == IP
* | MAC Header | IP Header | TCP Header | SMTP Header | User Data | == MAC
*
* </pre>
*
* The example is trimmed for simplicity, because the MAC (Medium Access Control) layer
* also contains a few more levels of encapsulation.
* Since the type of the payload is more or less independent from the encapsulating protocol,
* the header must be inspected before attempting to decode the payload. Hence, the
* encapsulation level varies and can't be deduced without actually looking into the packets.
*
* For actually working with captured frames, it's useful to identify the packets via names and
* insert them into a parent/child - relationship based on the encapsulation. This is why
* all packet classes derive from QObject. The amount of overhead caused by the QObject is
* not a problem in this case, because we're talking about a theoratical maximum of about
* 10 packets per captured frame. We need to stuff them into a searchable list anyway and the
* QObject also cares about destroying the sub-, (child-) packets.
*
* This enables us to perform a simple look for packets of a certain type:
* @code
* OPacketCapturer* pcap = new OPacketCapturer();
* pcap->open( "eth0" );
* OPacket* p = pcap->next();
* OIPPacket* ip = (OIPPacket*) p->child( "IP" ); // returns 0, if no such child exists
* odebug << "got ip packet from " << ip->fromIPAddress().toString() << " to " << ip->toIPAddress().toString() << oendl;
*
