摘　　要：通过对光纤网络带宽优化适配调节,提高网络的资源分配均衡性,提出基于资源频谱的光纤网络带宽自动适配方法。根据优先级业务调度方法建立光纤网络带适配的SDN(Software Defined Network)网络构架体系,通过对网络设备的控制与转发功能调节,采用带宽保障机制进行光纤网络业务流量的均衡配置,采用资源频谱的延迟调度方法,进行光纤网络资源频谱的多业务分级管理。为保障各类不同业务带宽需求,采用高能的物理计算系统结构进行光纤网络带宽的资源频谱均衡配置,实现对光纤网络的存储资源、系统资源、频谱资源的分类管理和适应性配置。测试表明,该方法有效降低了光纤网络带宽分配的延迟,提高了网络带宽利用率,无论是网络的读取和写入性能都有较大提升。By optimizing and adjusting the bandwidth of optical fiber network to improve the balance of network resource allocation,this paper proposes an automatic bandwidth adaptation method of optical fiber network based on resource spectrum.According to the priority service scheduling method,the SDN(Software Defined Network)network architecture system of optical fiber network with adaptation is established.By adjusting the control and forwarding functions of network equipment,the balanced configuration of optical fiber network service flow is carried out by adopting the bandwidth guarantee mechanism,and the multi-service hierarchical management of resource spectrum of optical fiber network is carried out by adopting the delayed scheduling method of resource spectrum.In order to ensure the bandwidth requirements of various services,The high-energy physical computing system structure is used to allocate the resource spectrum of the optical fiber network bandwidth in a balanced way,and the classified management and adaptive allocation of the storage resources,system resources and spectrum resources of the optical fiber network are realized.The test shows that this method effectively reduces the delay of bandwidth allocation in optical fiber network,improves the utilization of network bandwidth,and greatly improves the reading and writing performance of the network.
