【摘要】：针对电力企业数据业务流量爆炸性增长所引发的骨干网络带宽资源瓶颈问题,在对国家电网公司光传输网(optical transport network,OTN)大容量骨干传输网络承载业务需求分析基础上,从频谱管理方法、交叉连接设备、混合线速传输、控制平面等方面出发,探索FlexGrid技术在电力通信网络中的应用模式,可为电力通信骨干网络提供光层粒度的精细划分与动态调整能力。在此基础上,提出在多种约束条件下根据频谱资源利用度动态调节调制的信道资源管理方法,可有效改善现有骨干传输网络采用的固定带宽分配和管理模式造成网络灵活性差,带宽资源利用效率低下的现状。
[Abstract]:Aiming at the bottleneck of backbone network bandwidth caused by explosive growth of data traffic in electric power enterprises, this paper analyzes the demand of large capacity backbone transmission network of optical transmission network optical transport network of State Grid Company. From the aspects of spectrum management, cross-connection equipment, hybrid line speed transmission, control plane and so on, this paper explores the application mode of FlexGrid technology in electric power communication network. It can provide fine partition and dynamic adjustment ability of optical layer granularity for power communication backbone network. On this basis, a channel resource management method which dynamically adjusts modulation according to the utilization of spectrum resources under a variety of constraints is proposed, which can effectively improve the fixed bandwidth allocation and management mode used in the existing backbone transmission networks, resulting in poor network flexibility. The current situation of inefficient use of bandwidth resources.
