     16 All OpenFlow switches that are to perform the functions of a MobilityFirst router are connected to a central controller. As the sender starts to transmit data, the first packet of the chunk is sent to the controller since there is no matching flow rule as of yet. The controller uses the GUID  map it created using link probe messages to compute the out port on the switch and sends an appropriate flow rule. The rest of the packets are then forwarded by the switch. Chunks that have to be stored are sent to a software CLICK based router which can handle chunk storage.
