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;
