Abstract: PURPOSE: A method for allocating network resources by using a network resource threshold is provided to improve the resource utilization of the whole network by checking a network resource threshold as well as a link resource threshold for each link in order to determine whether a new path is to be created for a specific path. CONSTITUTION: A system creates the shortest path set from an arbitrary source node to a destination node(201). The system selects work paths and protect/recovery paths from the shortest path set(202). In case that a creation request for a work path and a protect/recovery path from an arbitrary source node to a destination node is generated(203), the system checks a link resource threshold for each of the links on the selected paths(204). Then the system confirms whether the ratio of the number of the whole wavelengths of each link to the number of presently used wavelengths exceeds a preset link resource threshold(205). In case that each link doesn't exceed the preset link resource threshold, the system determines the selected paths as requested paths(206). However, if a link exceeds the preset link resource threshold, the system checks a network resource threshold for the whole network usable for the setup of requested paths(207).
