A time slot selection device is provided that can consider resource use states on its own and allocate time slots. The time slot selection device performs time slot allocation, based on data link identifiers that identify a group of data links specified by a path setup request, a time slot size that is information about a required band, and a required number that is the number of contiguous time slots required. In this time slot selection device, a resource allocation section performs time slot selection, based on the resource use state of each time slot. By the time slot selection with consideration given to the use state of each time slot in the group of data links, time slots to be used can be selected so that a maximum number of contiguous usable time slots will be left. Thus, it is possible to efficiently use resources.
