    • The path management controller 1 refers to resource information 131 including reservation statuses of working paths and advance reserved paths that are set in every link, so as to calculate a route for setting a new path and set this path in this calculated route. If the route for setting this new path cannot be obtained (1) because of a shortage of residual bandwidth of a link of interest, the path management controller 1 refers to the resource reservation information 131 of working paths and advance reserved paths and calculates an alternative route for another existing path used in the link of interest, and moves this path to the calculated alternative route. On the other hand, if the route for setting this new path cannot be obtained (2) because there is no continuous bandwidth sufficient for setting this new path in the link of interest, the path management controller 1 refers to the resource reservation information regarding working paths and advance reserved paths in the link of interest in the resource information 131, so as to execute the time slot rearrangement.
    • 路径管理控制器1是指包括在每个链路中设定的工作路径和提前保留路径的预约状态的资源信息131,以计算用于设定新路径的路径,并在该计算出的路线中设定该路径。 如果由于缺少感兴趣的链路的剩余带宽而不能获得用于设置该新路径的路由(1),则路径管理控制器1参考工作路径的资源预约信息131和提前保留路径,并计算替代 路由用于感兴趣的链接中的另一个现有路径,并将该路径移动到计算的替代路由。 另一方面,如果不能获得用于设定该新路径的路径(2),因为没有足够的连续带宽来设定感兴趣的链路中的新路径,所以路径管理控制器1参考关于工作的资源预约信息 在资源信息131中感兴趣的链接中的路径和预先保留路径,以便执行时隙重排。
