摘要:
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.

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.

Provided is a distributed and asynchronous implicit token carrier sense multiple access/collision avoidance (CSMA/CA) protocol guaranteeing quality of service for both real time and non-real time traffic. The implicit token CSMA/CA protocol allocates a band in an entire bandwidth to voice traffic and allows the remaining bands to be used for data traffic. The implicit token CSMA/CA protocol includes applying a token passing protocol to transmit voice traffic in real time by having a band in an entire bandwidth allocated using a predetermined data frame and applying a CSMA/CA mechanism to transmit data traffic in non-real time by employing remaining bands not allocated to the voice traffic using another predetermined data frame.

The present invention discloses a packet capturing method using a kernel probe, which is for capturing traffic generated only by a specific application. The packet capturing method using a kernel probe comprises the steps of: acquiring the 5-tuple information of a packet associated with the application to capture by intercepting a specific set of operating system networking kernel functions using a kernel probe which intercepts calls to the functions; capturing packets inputted and outputted through a network device; and identifying traffic generated by the application by comparing the 5-tuple information with 5-tuple information of the captured packets.
