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: A method of controlling congestion of network equipment that connects networks with each other, includes determining a type of congestion based on a location of the network equipment; and identifying a network connection section having a strong possibility of occurrence of congestion based on the type of congestion, and setting a critical congestion bandwidth that is used to determine the occurrence of congestion. Further, the method includes identifying users required for equal distribution of traffic upon occurrence of congestion based on the critical congestion bandwidth; and equally distributing traffic to the identified users based on the critical congestion bandwidth, and then dropping an excess of arriving traffic over the equally distributed traffic, thereby performing avoidance of the congestion.
