◆ ExecuteActions()

void ns3::ofi::ExecuteActions	(	Ptr< OpenFlowSwitchNetDevice >	swtch,
		uint64_t	packet_uid,
		ofpbuf *	buffer,
		sw_flow_key *	key,
		const ofp_action_header *	actions,
		size_t	actions_len,
		int	ignore_no_fwd
	)

Executes a list of flow table actions.

Parameters

swtch	OpenFlowSwitchNetDevice these actions are being executed on.
packet_uid	Packet UID; used to fetch the packet and its metadata.
buffer	The Packet OpenFlow buffer.
key	The matching key for the flow tied to this list of actions.
actions	A buffer of actions.
actions_len	Length of actions buffer.
ignore_no_fwd	If true, during port forwarding actions, ports that are set to not forward are forced to forward.
