METHOD FOR DELIVERING EMERGENCY TRAFFIC IN SOFTWARE DEFINED NETWORKING NETWORKS AND APPARATUS FOR PERFORMING THE SAME |
摘要 |
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. |
