Abstract: Disclosed is a cell scheduling execution method taking the priority ranking and starvation into account. The cell scheduling execution method according to the present invention prevents a starvation phenomenon from occurring when a cell is meant to be transmitted but cannot be transmitted since the cell has a low priority rank by making the cell have a higher priority rank. Accordingly, the present invention can prevent a starvation phenomenon from occurring when high-priority cells are continuously transmitted from a particular input port to a particular output port and the input queue of another input port with low-priority cells targeting the same output port is not declining.

Abstract: If a transmitting device transmits an instant message, the transmitting device sets a notification command mode to instruct a notification process if a receiving device receives the message or a non-notification command mode to instruct a non-notification process if the receiving device receives the message. After that, the receiving device performs the notification process if the notification command mode is set in the received message and does not perform the notification process if the non-notification command mode is set in the received message.
Abstract translation: 如果发送设备发送即时消息，则发送设备设置通知命令模式，以指示通知处理，如果接收设备接收到该消息或者非通知命令模式来指示不通知处理，如果接收设备接收到消息 。 之后，如果在接收到的消息中设置了通知命令模式，则接收装置执行通知处理，并且如果在接收到的消息中设置了非通知命令模式，则不执行通知处理。

Abstract: A system and a method for measuring Internet traffic are provided to implement an extendable Internet traffic measurement environment through quickly processing data by adopting a hierarchical structure. A traffic collecting unit(10) collects traffic that flows through a network from a network equipment. Multiple servers(20) store data collected from the traffic collecting unit(10) in a storage unit(30) having a sufficient storage space, and transmit the stored data to an external application device according to a corresponding request from an upper source. The data storage unit(30) stores data. When a request is received from an arbitrary server, a network information processing unit(40) searches data from the storage unit(30) and processes it. A master server(50), which manages multiple servers(20), transfers the data obtained from the arbitrary server to the external application device in response to a corresponding request from the external application device.

Abstract: A VCG(Virtual Concatenation Group) management method in an EoS(Ethernet over SDH(Synchronous Digital Hierarchy)) transmission device is provided to manage a VCG in a software way, in order to allocate bandwidths effectively and dynamically in the EoS transmission device. A VCG management device receives VCG information set by an operator(S401,S402). The device defines the received VCG information as VCG data to generate the defined VCG data. The device sets the VCG data to a VCG channel on an SONET(Synchronous Optical Network)/SDH interface. The device manages the corresponding VCG channel by generating, modifying, and deleting data on the set VCG channel according to the VCG information set by the operator(S403-S417).

Abstract: A TCAM(Ternary Contents Address Memory) table management method is provided to be capable of effectively classifying and storing routing entries within a TCAM lookup table, thereby magnifying memory utility of a TCAM and more quickly and effectively updating the lookup table for newly inputted routing entries. Memory regions of a TCAM are divided into certain area blocks according to priority to configure a lookup table. The priority is allocated to each of all routing entries inputted to the lookup table according to the length of each prefix. The routing entries to which the priority is allocated are stored in lookup table blocks having the corresponding priority. The lookup table is changed so that aligned state for the longest prefix match is maintained according as a change is generated in the lookup table.

Abstract: A method for managing a failure state based on a result of protection switching operation in a transmission device is provided to enhance correctness of the failure state and enable an operator to perform property management by applying a unit failure state management mode according to the result of the protection switching operation. A control unit requests a failure state value controlled by units(412). The control unit stores the failure state value received from the controlled units(413). When a failure occurs in the controlled unit, a service is recovered by performing the protection switching operation(414). The result of the protection switching operation is determined by collecting result information for the performed protection switching operation(417). A failure level for the failure state value is selected by a determined result(419). The selected failure level is reported to an operation terminal(420).

Abstract: An apparatus and a method for detecting a network attack through traffic pattern analysis are provided to efficiently operate a network by actively detecting aggression or an abnormal situation on the network and preventing a network attack previously or coping with an attack act early enough. An apparatus for detecting a network attack through traffic pattern analysis comprises a pattern DB(40), a packet inspection part(10), a packet extraction part(20), a traffic analysis part(30), a traffic countermeasure part(50), and a traffic monitoring part(60). The pattern DB(40) stores abnormal traffic patterns, based on external attacks, and normal traffic patterns. The packet inspection part(10) checks an abnormal symptom of inputted packet flows. The packet extraction part(20) collects packet flows showing an abnormal symptom, and extracts a traffic pattern for the packet flows. The traffic analysis part(30) compares the extracted traffic pattern with traffic patterns stored in the pattern DB(40), and analyzes whether the extracted traffic pattern is by an external attack. The traffic countermeasure part(50), if the extracted traffic pattern is by an external attack, determines a countermeasure for the traffic. In case the extracted traffic pattern is not by an external attack, the traffic monitoring part(60) monitors traffic patterns for a preset time, extracts traffic patterns after the preset time, and transfers them to the traffic analysis part(30).
