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.

摘要： Power consumption on GMPLS controlled networks can be reduced by cutting power consumption on spare paths that are not normally used. To achieve power consumption reduction, in the path setting process, a path is calculated while taking the power saving capability of each interface into account, and the applicable interface is set to the power-saving state when setting the spare path. When the spare path was set to the operating state, then the power-saving state on the applicable interface was canceled so that interface could operate normally.

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： Information that is not dependent on how a GMPLS switch or an MPLS router is set up (information independent of the type of GMPLS switch or MPLS router) is used to obtain attribute values of communication paths and manage communication path configurations in a communication network. Provided is a communication path management system for managing a communication network system in which a communication path is established by transferring communication path establishment control information between data switching apparatuses, including: an information collecting module which collects the communication path establishment control information; an information accumulating module which accumulates the communication path establishment control information collected by the information collecting module; and an information searching module which searches the communication path establishment control information accumulated by the information accumulating module, wherein which communication path is established is derived from the communication path establishment control information searched by the information searching module.

摘要： In an MPLS or GMPLS network, links for hops of a communication path and adaptation to be implemented on the border of management domains or layers are automatically appropriately selected based on a service type or a requirement for maintenance. First, a unit that appends an identifier of a service to be provided and an attribute of the service to a communication path establishment control message, and requests path establishment is installed in a source node. Secondly, a unit that determines a requirement for maintenance of the communication path and adaptation on the basis of the service identifier and/or service attribute is installed in each node. Thirdly, maintenance attributes of network resources are compared with the requirement for maintenance in order to determine links and nodes through which the communication path passes. The determined links, nodes, and adaptation are designated as action parameters for a switching unit and/or interface unit.
