c - How do I identify the source of a UDP packet in an access point? -

i'm creating kind of access point. i capture packets, of types, machine, in order prioritize them before forwarding them, according default quality of service (qos) classes. by calling socket eth_p_all parameter , can incoming packets of protocol type: if ((sockfd = socket(af_packet, sock_raw, htons(eth_p_all))) == error) { perror("socket"); exit(1); } by using ethhdr , iphdr , tcphdr , udphdr structs can't retrieve information on application sent each packet. however, both voip , snmp use udp, , don't know of 2 sent me udp package. i'd know applications sending udp packets, may follow qos classes , forward packets (e.g. conversational voice) before others (e.g. e-mail). in order recognize protocol, should use list of tcp , udp port numbers? you cannot tell for sure application sent packet - sender knows this. if understand correctly, want detect protocol being used. have 2 possibilities: assume appli...
