Abstract
An apparatus stores information identifying unallocated channels for each of spans, where a span indicates a section between adjacent nodes of a plurality of nodes in a communication network. The apparatus extracts unallocated channels for each of all spans provided between a start point node and an end point node of a path in the communication network, by referring to the information, and determines a channel including consecutive unallocated spans which are arranged on routes including the path and spans outside the path, and whose number is minimum among the extracted unallocated channels, as a channel to be set to the path.
