Abstract: Disclosed are a method for delivering emergency traffic in a SDN based network and an apparatus performing the same. A method for delivering emergency traffic, performed in a controller, may comprise generating an emergency code for delivering the emergency traffic when an emergency state corresponding to a predefined type occurs; transmitting the emergency code to a first OpenFlow switch connected to a transmitting terminal transmitting the emergency traffic; and transmitting a message directing an update of the emergency code to at least one OpenFlow switch included in a forwarding path of the emergency traffic. Therefore, when an emergency state occurs in a network, emergency traffic corresponding to the emergency state may be delivered efficiently, and stabilities of network management and service qualities may be guaranteed accordingly.

Abstract: There are provided a data transmission method of a multi-hop network and a device using the same. The data transmission method of the multi-hop network according to the invention may include receiving information on the multi-hop network, receiving a predetermined desired communication reliability (DCR) of data transmission from a source node to a sink node, determining a single-hop packet transmission rate of each node from the source node to the sink node satisfying the predetermined desired DCR based on the information on the multi-hop network, and notifying each node configuring the multi-hop network of the single-hop packet transmission rate of each of the nodes. In the method and device according to the invention, it is possible to satisfy the DCR required for the multi-hop network and decrease energy consumption by minimizing the total number of transmitted packets.
