Functions

func NewConfigRequest 

func NewConfigRequest() *ofpxx.Header

func NewEchoReply 

func NewEchoReply() *ofpxx.Header

Echo request/reply messages can be sent from either the switch or the controller, and must return an echo reply. They can be used to indicate the latency, bandwidth, and/or liveness of a controller-switch connection.

func NewEchoRequest 

func NewEchoRequest() *ofpxx.Header

Echo request/reply messages can be sent from either the switch or the controller, and must return an echo reply. They can be used to indicate the latency, bandwidth, and/or liveness of a controller-switch connection.

func NewFeaturesRequest 

func NewFeaturesRequest() *ofpxx.Header

FeaturesRequest constructor

func Parse 

func Parse(b []byte) (message util.Message, err error)

Types

type Action 

type Action interface {
	Header() *ActionHeader
	util.Message
}

func DecodeAction 

func DecodeAction(data []byte) Action

TODO: Decode other Action types.

type ActionDLAddr 

type ActionDLAddr struct {
	ActionHeader
	DLAddr net.HardwareAddr
	// contains filtered or unexported fields
}

The dl_addr field is the MAC address to set.

func NewActionDLDst 

func NewActionDLDst(dlAddr net.HardwareAddr) *ActionDLAddr

Sets the destination MAC adddress to dlAddr

func NewActionDLSrc 

func NewActionDLSrc(dlAddr net.HardwareAddr) *ActionDLAddr

func (*ActionDLAddr) Len 

func (a *ActionDLAddr) Len() (n uint16)

func (*ActionDLAddr) MarshalBinary

type ActionEnqueue 

type ActionEnqueue struct {
	ActionHeader
	Port uint16

	QueueId uint32
	// contains filtered or unexported fields
}

The enqueue action maps a flow to an already-configured queue, regardless of the TOS and VLAN PCP bits. The packet should not change after an enqueue action. If the switch needs to set the TOS/PCP bits for internal handling, the original values should be restored before sending the packet out. A switch may support only queues that are tied to specific PCP/TOS bits. In that case, we cannot map an arbitrary flow to a specific queue, therefore the action ENQUEUE is not supported. The user can still use these queues and map flows to them by setting the relevant fields (TOS, VLAN PCP).

	Port   uint16
	MaxLen uint16
}

Action structure for OFPAT_OUTPUT, which sends packets out ’port’. When the ’port’ is the OFPP_CONTROLLER, ’max_len’ indicates the max number of bytes to send. A ’max_len’ of zero means no bytes of the packet should be sent.

type ActionStripVLAN 

type ActionStripVLAN struct {
	ActionHeader
	// contains filtered or unexported fields

type ActionVLANPCP 

type ActionVLANPCP struct {
	ActionHeader
	VLANPCP uint8
	// contains filtered or unexported fields

When the controller wishes to send a packet out through the datapath, it uses the OFPT_PACKET_OUT message: The buffer_id is the same given in the ofp_packet_in message. If the buffer_id is -1, then the packet data is included in the data array. If OFPP_TABLE is specified as the output port of an action, the in_port in the packet_out message is used in the flow table lookup.
