Abstract: An apparatus for processing multicast traffic in an OpenFlow environment, includes: a network topology and configuration information management unit configured to generate network topology and related switch configuration information based on switch configuration information received from one or more OpenFlow switches. Further, the apparatus includes a path information processing unit configured to, when traffic for video conference service is received, generate ring-type transmission path information to be used to process the traffic, based on the network topology and related switch configuration information, and set the ring-type transmission path information in one or more OpenFlow switches to be used for the video conference service, thereby setting up a ring-type transmission path.

Abstract: The present disclosure relates to a system and a method for managing filtering information of attack traffic, and more particularly, to a system and a method for managing filtering information of attack traffic that may block attack traffic in a front end from which the attack traffic is transmitted by transmitting traffic filtering information, to a first autonomous system of the front end from which the attack traffic is transmitted, through a border gateway protocol (BGP) and by applying, to a relevant router, the transmitted traffic filtering information in the corresponding first autonomous system, when an edge router of a second autonomous system (AS) positioned in a rear end sets the traffic filtering information by detecting the attack traffic.
