Class KrakenIpv4Handler

java.lang.Object

at.jku.fim.rubanetra.protocol.KrakenBaseProtocol

at.jku.fim.rubanetra.protocol.handler.KrakenIpv4Handler

All Implemented Interfaces:

BaseProtocol

public class KrakenIpv4Handler
extends KrakenBaseProtocol

This is an inefficient handler for Kraken's IpDecoder implementation. Since the utilized IP next protocol numbers are not known a priori this class registers all numbers in the range [0x01;0xFF[ during initialization. Forward bindings are provided for:

• KrakenUdpHandler
• KrakenTcpHandler
• KrakenIcmpv4Handler

Method Detail

getProtocolId

public ProtocolId getProtocolId()

Description copied from interface: BaseProtocol

An arbitrary identifier for the protocol(s) this decoder should be able to parse and decode. This identifier must be unique and may not be reused multiple times inside this framework for multiple decoders, even if the same protocol can be decoded by multiple implementations.

Returns:

a unique identifier used to represent the decoding capabilities of this decoder

initialize

public void initialize(KrakenProtocolConfiguration setting)

Description copied from class: KrakenBaseProtocol

Initializes this protocol decoder with the information provided by the user. This method will be called once by KrakenProtocolConfigurationBuilderImpl before the bindings are processed. This method should be called exactly once, multiple calls will result in an exception being thrown.

Overrides:

initialize in class KrakenBaseProtocol

Parameters:

setting - the protocol configuration provided by the user

bind

public void bind(KrakenEthernetProtocolHandler ethernetProtocol)

An experimental backward binding, i.e. it registers ethernetProtocol Kraken decoder to this IPv4 decoder

Parameters:

ethernetProtocol - the Ethernet decoder to bind to this IPv4 decoder

bind

public void bind(KrakenTcpHandler tcpProtocol)

Forward binding to the tcpProtocol internal TCP decoder, i.e. all decoded IPv4 packets are forwarded to the TCP handler.

Parameters:

tcpProtocol - the handler for the decoded IPv4 packets

bind

public void bind(KrakenUdpHandler udpProtocol)

Forward binding to the udpProtocol internal UDP decoder, i.e. all decoded IPv4 packets are forwarded to this UDP handler.

Parameters:

udpProtocol - the handler for the decoded IPv4 packets

bind

public void bind(KrakenIcmpv4Handler icmpv4Handler)

Bind the internal IpDecoder to an ICMPv4 decoder, i.e. a decoder that shall receive all decoded IP packets.

Parameters:

icmpv4Handler - the ICMPv4 decoder to bind to

Throws:

IllegalArgumentException - if the parameter is a null pointer

getKrakenIpv4Decoder

public org.krakenapps.pcap.decoder.ip.IpDecoder getKrakenIpv4Decoder()

Returns:

the internal IPv4 decoder
