SCHEDULER, OPTICAL TDM TRANSMISSION SYSTEM, SCHEDULING METHOD, AND SCHEDULING PROGRAM

摘要

A scheduler (10) has a time slot allocation unit (15) that: regarding signals to be transmitted in a metro surface (140) not via a core surface (130), controls a metro node (40) on the basis of first scheduling information indicating that the signals are to be allocated to a first TS at intervals of a first GT from each other; and regarding signals to be transmitted between different metro surfaces (140) via the core surface (130), controls a core node (30) on the basis of second scheduling information indicating that a plurality of first TSs having the same combination of a transmission source metro surface and a reception destination metro surface are to be allocated to a second TS at intervals of a second GT longer than the first GT from each other.
