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

static TypeId ns3::ofi::LearningController::GetTypeId ( void  )

static

This method returns the TypeId associated to ns3::Object.

No Attributes defined for this type.
No TraceSources defined for this type.

Reimplemented from ns3::ofi::Controller.

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:

swtch	The switch the message was received from.
buffer	The message.
