Detailed Description

Demonstration of a Learning controller. When a connected switch passes it a packet the switch doesn't recognize, the controller delves into its learned states and figures out if we know what port the packet is supposed to go to, flooding if unknown, and adjusts the switch's flow table accordingly.

Member Function Documentation

void ns3::ofi::LearningController::ReceiveFromSwitch ( Ptr< OpenFlowSwitchNetDevice swtch,
ofpbuf *  buffer 
)
virtual

A switch calls this method to pass a message on to the Controller.

Parameters
swtchThe switch the message was received from.
bufferThe message.

Reimplemented from ns3::ofi::Controller.
