The embodiment of the invention discloses a network management device and a method for managing the idle time slot of the ODUflex frame. The method comprises: carrying other services for the ODUflex business use of reserved idle bandwidth, and to determine whether the path of carrying ODUflex business office of a chain section of the idle bandwidth to meet increased ODUflex traffic bandwidth demand; if not satisfied by the path and record the alternate path information for the chain sections of the Business Computing, the backup path the information includes the calculation of the alternate path backup path of business; in response to increasing ODUflex bandwidth instruction, standby path information recording, the business section of the bearing the chain switch to the standby path corresponding to the alternate path according to the information, to make idle bandwidth to meet the increasing ODUflex bandwidth demand; and chain section adjustment and path bandwidth adjustment, thereby increasing the bandwidth of ODUflex. The above method of managing free time slots can reduce bandwidth waste and prevent a lack of bandwidth when adjusting ODUflex traffic bandwidth.

１．一种网管设备管理ＯＤＵｆｌｅｘ帧的空闲时隙的方法，其特征在于，该方法包括：利用为ＯＤＵｆｌｅｘ业务预留的空闲带宽承载其他业务，并确定承载ＯＤＵｆｌｅｘ业务的路径上任一链路段的空闲带宽是否大于等于ＯＤＵｆｌｅｘ业务的最大承诺带宽减去ＯＤＵｆｌｅｘ业务占用带宽的差值；当确定承载ＯＤＵｆｌｅｘ业务的路径上任一链路段的空闲带宽小于ＯＤＵｆｌｅｘ业务的最大承诺带宽减去ＯＤＵｆｌｅｘ业务占用带宽的差值时，为该链路段上的业务计算备用路径并记录备用路径信息，所述备用路径信息包括成功计算出备用路径的业务及其备用路径；响应增加ＯＤＵｆｌｅｘ业务带宽的指令，获取记录的备用路径信息，根据该备用路径信息将该链路段上承载的业务切换到对应的备用路径上，以腾出空闲带宽满足增加ＯＤＵｆｌｅｘ业务带宽的需求；及进行链路段调整和路径带宽调整，从而增加ＯＤＵｆｌｅｘ业务带宽。
