In an apparatus and method of selecting a label switched path (LSP) in a network management system, a status analyzing unit analyzes and digitizes performance information, fault occurrence, and fault history of a link. A link weight managing unit which determines link weight values using a predetermined weight calculation algorithm on second constraints that corresponds to qualitative information related to performance analysis of a path. An LSP selecting unit selects a path, from among paths on a path list, that satisfies first constraints which corresponds to objective information related to a path selection required by the administrative network policy, and, when there are several selected paths, selects a path that minimizes expense using the link weight values.

Provided are an apparatus and method of selecting a label switched path (LSP) in a network management system. The apparatus comprises a status analyzing unit which analyzes and digitizes performance information, fault occurrence, and fault history of a link in order to convert the performance information, fault occurrence, and fault history into standardized values, a link weight managing unit which determines link weight values using values obtained by adding and subtracting reference values, calculated using a predetermined weight calculation algorithm on second constraints that corresponds to qualitative information related to performance analysis of a path required by an administrative network policy, to and from the standardized values of the status analyzing unit, and an LSP selecting unit which prepares a path list by using a method of executing a predetermined background task by appointing a source and a destination from among all nodes in the administrative network, selects a path, from among paths on the path list, that satisfies first constraints which corresponds to objective information related to a path selection required by the administrative network policy, and, when there are several selected paths, selects a path that minimizes expense using the link weight values. Using the apparatus, the optimum path according to the administrative network policy can be selected.

Provided is a method and system for providing a QoS in a broadband convergence network deploying a mobile IP. In the method, a service and policy is defined at a first network design stage for guaranteeing the QoS of the broadband convergence network. QoS parameters corresponding to the defined service and policy are reflected in a DSCP field corresponding to the defined service. The DSCP field and the QoS parameters are applied to an access router in a management network. Accordingly, the QoS can be guaranteed to be suitable for the service and policy and a seamless handover guaranteeing the QoS can be provided.

A bottom-up (or upward) multilayer network recovery method and apparatus based on a root-cause analysis are disclosed to quickly and accurately perform a recovery operation. The bottom-up multilayer network recovery method based on a root-cause analysis includes: simultaneously counting, by a fault detection layer, a root-cause analysis (RA) time and a hold-off (HO) time, upon detecting an occurrence of a fault; performing, by the fault detection layer, a root-cause analysis during the RA time to recognize a layer in which a root-cause has occurred; when the root-cause has occurred in the fault detection layer, immediately recovering the fault by the fault detection layer, and when a root-cause has occurrence in a lower layer, waiting for the HO time until such time as the lower layer can recover the fault; and when the fault has not been recovered even after the HO time has lapsed, recovering the fault by the fault detection layer.

An integration agent device and its fault management method for a node including multi-layered devices are disclosed to effectively control a node including two or more communication devices of different layers and integrally processing relevant fault information. The integration agent device includes: one or more control and management modules controlling and managing one or more communications network devices by layer; and an inter-layer interworking processing module integrating and processing information of the communications network devices by using inter-layer interworking information, and notifying a management system accordingly, wherein the information of the communications network devices is transmitted through the one or more control and management.

A method and system for processing billing of including QoS information are provided. In the method, a call is initiated by transmitting/receiving packets directly to/from an opponent terminal after signaling with the opponent terminal using a session initiation protocol through the signaling server. Then, QoS of the call is measured while communicating with the opponent terminal. A billing process is performed of including the QoS measuring result by transmitting the QoS measuring result to the signaling server after the call established to the opponent terminal is terminated.

Disclosed is a routing method and apparatus for providing a different path by service. The routing method includes determining a service identification (ID) indicating a service requested by a packet by using a header in the packet; and searching for a service forwarding table corresponding to the service ID from a plurality of service forwarding tables storing different next hops by service and determining the packet's next hop.
摘要:
A method and apparatus for aggregating single packets in a single session are disclosed. If the amount of single packets in a single session exceeds a threshold value, it is detected that attack traffic is being inputted and the single packets in the single session are aggregated into a single flow, thus preventing degradation of a network performance due to the single packets in the single session.
