Constructor Detail

UdpPacket

public UdpPacket(UDP udp)

Construct a new instance.

Parameters:

udp - A UDP instance.

Method Detail

createMatch

protected VTNUdpMatch createMatch(VTNPortRange src,
                                  VTNPortRange dst)

Construct UDP flow match fields.

Specified by:

createMatch in class PortProtoPacket<UDP>

Parameters:

src - A VTNPortRange instance which specifies the source port.

dst - A VTNPortRange instance which specifies the destination port.

Returns:

A VTNUdpMatch instance.

getSourceMatchType

public FlowMatchType getSourceMatchType()

Return a flow match type corresponding to the source port.

Specified by:

getSourceMatchType in class PortProtoPacket<UDP>

Returns:

FlowMatchType.UDP_SRC.

getDestinationMatchType

public FlowMatchType getDestinationMatchType()

Return a flow match type corresponding to the destination port.

Specified by:

getDestinationMatchType in class PortProtoPacket<UDP>

Returns:

FlowMatchType.UDP_DST.

updateChecksum

public boolean updateChecksum(Inet4Packet ipv4)
                       throws VTNException

Calculate the checksum of the packet, and set the computed checksum into a Packet instance configured in this instance.

Specified by:

updateChecksum in interface L4Packet

Parameters:

ipv4 - An Inet4Packet instance that contains this packet.

Returns:

true is returned if the checksum field was updated. false is returned if the packet was not modified.

Throws:

VTNException - An error occurred.
