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.

There is provided a method of controlling routes and resources in a packet-optic convergence network. The method includes receiving PTL route information between edge devices of the packet-optic convergence network, in which the PTL route information is provided through a route management system; monitoring a resource use state according to PTL route in the process of reserving, changing, or releasing resources in response to a request for the reservation, change, or release of the resources by a service control system; and changing PTL routes or resources allocated to the PTL routes through the route management system on the basis of the resource use state according to PTL route, thereby ensuring greater stability in providing an IP premium service with a Quality of Service (QoS) guarantee.

A traffic measurement system and a traffic analysis method are provided. The traffic measurement system includes a plurality of measurement devices that collect all of packets flowing through Internet links, extract traffic data required to analyze traffic from the collected packets, and process the extracted data into predetermined flow types, and an analysis server that identifies applications of traffic by analyzing the traffic data transferred from the plurality of measurement devices as a whole, classifies the identified applications into predetermined traffic types, and outputs the classification result. The traffic measurement system measures the traffics in the Internet network and processes the measured traffics to generate detailed traffic statistical data according to applications. In particular, the traffics are analyzed considering measurement data from various points, and the data for identifying the applications are extracted from headers of the applications included in payloads of IP packets in real time. Accordingly, detailed traffic analysis result is provided.

Disclosed is an inter-layer path provisioning method and system in a multilayer network that may set, in response to a path setting request of an operator, an upper layer path to be interlocked with an upper layer path computation unit, set, separately from the setting of the upper layer path, a lower layer path to be interlocked with a lower layer path computation unit, and perform a connection between the set upper layer path and the set lower layer path, so that inter-layer path setting may be readily performed in a multilayer transport network.
摘要:
A first path control management system of a first domain calculates a path in the first domain and transmits information of a connection node in the first domain to connect to a second domain to a second path control management system of the second domain. The second path control management system of the second domain calculates a path in the second domain and transmits a connection node of the second domain to connect to the first domain to the first path control management system. The first path control management system of the first domain and the second path control management system of the second domain receive information of connection nodes of the second domain and the first domain, respectively, thereby connecting a path between the first domain and the second domain.

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.
