Abstract: An illegal call detection apparatus comprises a data collecting unit, a preprocessing unit, and a learning unit. The data collecting unit collects, from at least one of a subscriber terminal or a call exchanger, a raw packet generated by the subscriber terminal using a VoIP service, and collects, from the billing server, CDR data related to the raw packet. The preprocessing unit generates learning data by using service usage information extracted from the CDR data and service detailed information extracted from the raw packet, and generates a training image by converting the training data into an image according to a predetermined imaging rule. The learning unit extracts at least one or more features from the training image, and learns whether the training image is related to an illegal call by using the features, through an illegal call detection model.

Abstract: Disclosed is a bandwidth providing method based on multi-flow grouping, which can control multi-terminal and multi-service for a user with a single bandwidth. The bandwidth providing method based on multi-flow grouping comprises a step of receiving a first packet flow and a second packet flow, a step of verifying a flow group comprising the first package flow and the second package flow using a flow group table, and a step of assigning a single bandwidth to the first packet flow and the second packet flow when the first packet flow and the second packet flow are verified as being comprised in the same group, thereby managing the bandwidth. Accordingly, the multi-terminal and multi-service of a user can be efficiently controlled with a single bandwidth.

Abstract: A method for processing an event between a controller and a network device is disclosed. A method for processing an event in a network device comprises the steps of: receiving an event notification registration request from a controller; monitoring the occurrence of an event corresponding to the event notification registration request and; when an event occurs, notifying the event occurrence to the controller. Thus, the controller can reduce the load through reducing the number of times of message transmissions for monitoring the event by a switch.

Abstract: Disclosed is a method for updating a flow table for a switch in software defined networking (SDN). The method for updating a flow table of at least one network device by a controller in a software defined network comprises the steps of: transmitting, to at least one network device, a flow table modification message including information on a scheduled time specifying a time at which updating of the flow table is performed; and receiving, from at least one network device, a result message showing an update result on the flow table performed by at least one network device according to the flow table modification message. Accordingly, it is possible to effectively control a load generated on the controller by controlling intervals of updating times between network devices, which is generated during transmission of the flow table modification message to multiple network devices.

Abstract: Disclosed is a method for changing a role over control authorization performed in a communication apparatus. The method may comprise receiving, from a second controller, a role-request message requesting a role change of the second controller to a master controller; transmitting a role status request message for confirmation of the role change of the second controller to a first controller which is a previous master controller; and determining whether to accept the role change of the second controller according to a role status response message received from the first controller. Therefore, reliability may be guaranteed when a role of master controller is changed.

Abstract: Disclosed are a packet output controlling method and a network device using the same. A packet output controlling method according to the present invention, as a method for processing flow in a plurality (N, where N is a natural number of 2 or greater) of flow tables connected by a pipeline, may comprise the steps of: passing a packet input into a flow from a first table to an N?1st table from among a plurality of tables; processing an output-dedicated Nth table (egress table) guided by the N?1st table with respect to the packet after the packet passes the N?1st table; and outputting the packet after processing the Nth table. Accordingly, the flexible control of a final output is made possible through various operations using output port information.

Abstract: A method and device for processing an address resolution protocol (ARP) in a software-defined networking (SDN) environment is disclosed. The method includes receiving, by a first network device, an ARP request packet from a first terminal so that the first terminal communicates with a second terminal and transmitting, by the first network device, an ARP response message including MAC address information of the second terminal to the first terminal as a response to the ARP request packet. Accordingly, a load of the controller can be reduced by sharing and processing an ARP proxy function with the network device in the SDN environment.

The method for dynamic traffic control comprises the steps of: creating at least one flow entry for controlling the traffic of the network device; and controlling the traffic of the network device by transferring the created at least one flow entry to the network device, wherein the at least one flow entry contains information of a threshold value or a target value for the traffic for controlling the traffic. Accordingly, a communication load between the network device and the controller and a system load of the network device can be reduced. Further, it is possible to provide real-time service through a dynamic traffic control.
