Header Examples

IPv4

Ip4 ip = new Ip4();
if (packet.hasHeader(ip)) {
    System.out.println(ip.src() + " → " + ip.dst());
    System.out.println("TTL: " + ip.ttl());
    System.out.println("DF: " + ip.flagDf() + ", MF: " + ip.flagMf());
}

TCP

Tcp tcp = new Tcp();
if (packet.hasHeader(tcp)) {
    System.out.println(tcp.srcPort() + " → " + tcp.dstPort());
    System.out.println("SYN: " + tcp.flagSyn() + ", ACK: " + tcp.flagAck());
    if (tcp.hasOption(TcpOption.MSS)) {
        System.out.println("MSS: " + tcp.optionMss());
    }
}

HTTP

Http http = new Http();
if (packet.hasHeader(http)) {
    if (http.isRequest()) {
        System.out.println(http.method() + " " + http.uri());
    } else {
        System.out.println(http.statusCode() + " " + http.reasonPhrase());
    }
    System.out.println("Content-Type: " + http.header("Content-Type"));
}

GTP

Gtp gtp = new Gtp();
if (packet.hasHeader(gtp)) {
    System.out.println("TEID: " + gtp.teid());
    System.out.println("Message Type: " + gtp.messageType());
}

Custom Protocol Packs

You can create custom protocol packs for proprietary or specialized protocols:

public class MyProtocolProvider implements ProtocolProvider {
    
    @Override
    public int packId() { 
        return 0x8000;  // User-defined range
    }
    
    @Override
    public String packName() { 
        return "myprotocol"; 
    }
    
    @Override
    public Protocol findProtocol(int protocolId) {
        // Return protocol configurations
    }
}

Register via SPI:
