Abrégé
(EN)
The invention relates to an ultra low loss optical fiber replacement scheduling method and system in a backbone network for improving the spectrum utilization efficiency of an operator. The method provided by the invention comprises the following steps: S1 calculating gains after the replacement of optical fiber links, that is, calculating remaining times of reduced frequency slot FS after the replacement of the optical fiber links to complete replacement of the rest optical fiber links; S2, selecting the optical fiber link with the highest gain after the replacement of one optical fiber linkfor replacement; and repeating S1 to S2 until all optical fiber links needing to be replaced are completely replaced. According to the ultra low loss optical fiber replacement scheduling method and system, by determining the most reasonable optical fiber replacement sequence, the spectrum resources are saved for the operators as much as possible for additional service use.

本发明涉及一种骨干网中超低损耗光纤替换调度方法及系统,为了提高运营商的频谱使用效率而设计。本发明所述的方包括:S1分别计算各光纤链路替换后的增益,也即计算各光纤链路进行替换后减少的频隙FS数乘以到完成其余光纤链路全部替换剩余的时间;S2选择其中一个光纤链路替换后的增益最高的光纤链路进行替换;重复S1至S2,直至所有需要被替换的光纤链路全部替换完成。本发明通过确定最合理安排光纤的替换顺序,为运营商尽可能的节省频谱资源,供额外的业务使用。
