摘要:
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.

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.

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.
摘要:
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.
