Abstract: In a looped-bus type network, in case of a node error, an optical switching apparatus passes a service data in order to not receive an influence of an error node, and normally maintains a service data path. The light switching apparatus includes: a previous node input signal optical distributing unit(10) for dividing a data optical power with a ratio N:M; a present node input signal optical distributing unit(20) for dividing a data optical power from a present node/terminal; a node error monitoring/switching controller(30) for monitoring a distributed optical signal of 10% from the unit(10), and generating an optical switch control signal; a previous node optical signal controller(40) for controlling a distributed optical signal of N% from the unit(10); a present node controller(50) for controlling a distributed optical signal of 90% from the unit(20); and a optical signal connector(60) for interconnecting the optical signals from the controllers(40,50).

Abstract: Disclosed are a method for transferring an emergency traffic in a software defined networking network and an apparatus performing the same. The method for transferring the emergency traffic in an open flow control device generates an emergency code for transferring the emergency traffic if an emergency state belonging to a predefined type occurs; transmits the generated emergency code to a first open flow switch connected to a transmission terminal transmitting the emergency traffic; and transmits a message for commanding update of the emergency code to at least one open flow switch included in a transferring path of the emergency traffic, thereby making each open flow switch recognize and transfer the emergency traffic. Thus, the method can efficiently transfer the emergency traffic in the software defined networking network.

Abstract: Disclosed are a method for providing a quality of service (QoS) in a software-defined networking based network and an apparatus thereof. The method for providing the QoS comprises the steps of searching for forwarding information and QoS rule information corresponding to a first packet of a received predetermined flow in a forwarding table and a QoS rule table, respectively; transmitting the packet to a controller if the forwarding information and the QoS rule information do not exist in the forwarding table and the QoS rule table; and generating a flow entry corresponding to the packet in a flow learning table based on the forwarding information and the QoS rule information that are received from the controller, thereby efficiently providing the QoS.
