Types

type BaseLayer

type BaseLayer struct {
	// Contents is the set of bytes that make up this layer.  IE: for an
	// Ethernet packet, this would be the set of bytes making up the
	// Ethernet frame.
	Contents []byte
	// Payload is the set of bytes contained by (but not part of) this
	// Layer.  Again, to take Ethernet as an example, this would be the
	// set of bytes encapsulated by the Ethernet protocol.
	Payload []byte
}

-----------------------------------------***********************--------------------------------- BaseLayer is a convenience struct which implements the LayerData and LayerPayload functions of the Layer interface.

type IGMP

type IGMP struct {
	BaseLayer
	Type                    IGMPType
	MaxResponseTime         time.Duration
	Checksum                uint16
	GroupAddress            net.IP
	SupressRouterProcessing bool
	RobustnessValue         uint8
	IntervalTime            time.Duration
	SourceAddresses         []net.IP
	NumberOfGroupRecords    uint16
	NumberOfSources         uint16
	GroupRecords            []IGMPv3GroupRecord
	Version                 uint8 // IGMP protocol version
}

func (IGMP) LayerType

func (IGMP) LayerType() gopacket.LayerType

func (IGMP) SerializeTo

func (igmp IGMP) SerializeTo(b gopacket.SerializeBuffer, opts gopacket.SerializeOptions) error

SerializeTo writes the serialized form of this layer into the SerializationBuffer, implementing gopacket.SerializableLayer. See the docs for gopacket.SerializableLayer for more info.

type IGMPType

type IGMPType uint8

type IGMPv3GroupRecord

type IGMPv3GroupRecord struct {
	Type             IGMPv3GroupRecordType
	AuxDataLen       uint8 // this should always be 0 as per IGMPv3 spec.
	NumberOfSources  uint16
	MulticastAddress net.IP
	SourceAddresses  []net.IP
	AuxData          uint32 // NOT USED
}

IGMPv3GroupRecord stores individual group records for a V3 Membership Report message.
