Function Documentation

◆ 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
swtchOpenFlowSwitchNetDevice these actions are being executed on.
packet_uidPacket UID; used to fetch the packet and its metadata.
bufferThe Packet OpenFlow buffer.
keyThe matching key for the flow tied to this list of actions.
actionsA buffer of actions.
actions_lenLength of actions buffer.
ignore_no_fwdIf true, during port forwarding actions, ports that are set to not forward are forced to forward.
