A system according to claim 1, wherein said evaluation function determines selectively whether the fault restoration process is performed in the same layer as said faulty path or using a path of another layer accommodating said faulty path. 3. A system according to claim 2, wherein said evaluation function makes said determination according to the traffic utilization rate of the faulty path, and selects the fault restoration process by a path in the layer on the client side in the case where said utilization rate is not more than a predetermined threshold value. 4. A system according to claim 2, wherein said communication path restoration select unit includes an alternative path construction possibility information and said evaluation function selects another layer in the case where said alternative path construction possibility information is negative. 5. A communication path fault restoration system for a communication network including communications paths having a multiple layered structure, comprising: a communication path fault receiving unit for detecting a faulty path in accordance with collected network information; a communication path restoration select unit for selecting one communication layer from multiple communication layers and a communication path on the selected communication layer for dynamic fault restoration of the faulty path without preparing a spare path thereof, by calculating the value of a predetermined evaluation function based on information for said faulty path; and a communication path restoration processing unit for performing the fault restoration of said faulty path using the communication path on the selected communication layer; wherein said evaluation function determines selectively whether the fault restoration process is performed in the same layer as said faulty path or using a path of another layer accommodating said faultt path, and wherein said communication path restoration select unit further includes priority information assigned to each communication path, and said evaluation function selects the process in the same layer in priority against a communication path fault high in priority. 6. A communication path fault restoration system for a communication network including communications paths having a multiple layered structure, comprising: a communication path fault receiving unit for detecting a faulty path in accordance with collected network information; a communication path restoration select unit for selecting one communication layer different from a communication layer having the faulty path from multiple communication layers and a communication path on the selected communication layer for dynamic fault restoration of the faulty path without preparing a spare path thereof, by calculating the value of a predetermined evaluation function based on information for said faulty path; and a communication path restoration processing unit for performing the fault restoration of said faulty path using the communication path on the selected communication layer; wherein said communication path restoration select unit repeats the determination using said evaluation function on said selected communication layer thereby to further select one communication layer from the multiple communication laye
