摘要： A position in which an optical signal characteristic is compensated in an optical network can be chosen. An optical network equipment measures an optical signal characteristic for each wavelength, and notifies an optical network equipment on a communication path of an optical signal characteristic index and control necessity determination threshold. In an upstream portion of the communication path, the optical network equipment (a start point or the like of the communication path) that can compensate the optical signal characteristic for each wavelength determines the necessity to eliminate a deviation between wavelengths and the position to eliminate it, using the optical signal characteristic index and the control necessity determination threshold. The equipment determines a compensator to be controlled, and a compensation amount, based on the result, and commands an optical network equipment including the compensator to control the compensator, using a communication path establishment control protocol such as GMPLS-extended RSVP-TE.

摘要： In an MPLS/GMPLS network, a link used by a communication path for each hop and adaptations used at the boundary between management domains or layers are appropriately and automatically selected according to a service type and a required maintenance condition, without making a control sequence complicated. First, a unit for requesting path establishment by including an identifier of a service to be provided and a service attribute in a communication path establishment control message is provided for a source node. Second, a unit for determining a required maintenance condition for a communication path and adaptations according to the service identifier and/or the service attribute is provided for each node. Third, links and nodes through which the communication path passes are determined by comparing each of achievable maintenance conditions for network resources with the required maintenance condition. The determined links, nodes, adaptations are specified as operation parameters in switches and/or interfaces.

摘要： In a network wherein a data plane for communicating user data, and a control plane for managing data forwarders are configured of different media, the path teardown of the data plane which is forwarding the data is prevented when a fault has occurred in only the control plane. When the GMPLS controller of the control plane has detected refresh timeout with respect to an adjacent node (101 in FIG. 1), it checks whether or not a transmission equipment corresponding to a faulty controller has a fault (102), and it maintains a path state (103) in a case where the fault is limited to the control plane. Thus, the exchange of refresh messages with the adjacent node is continued without cleaning up the resources of the transmission equipment (104 through 107).

摘要： In generation of an MPLS path which extends over plural routing areas or generation of a GMPLS path of a single routing area, a path originating node cannot conduct route computation of the whole path. Therefore, where plural paths are generated, there is a problem that reliability and communication quality cannot be secured. In a label switch path generation processing intended for MPLS and GMPLS networks, a path originating node is provided with a unit for setting restricted link information in a label allocation request message and sending it, and a node having received the label allocation request message is provided with a unit for selecting another route, which does not pass through the restricted link according to the restricted link information, and generating a path.
