ip_packet Class Reference

The ip_packet class contains the information extracted from a packet received using pcap for packets that are IP/TCP or IP/UDP. We only save src and dst addresses and ports, and type of Transport protocol. The class hinerates the fields hardware address field because every IP packet is part of a ethernet packet. The remaining packet is stored as payload. More...
