基于路由与频谱管理的依赖关系,提出了一种频谱自觉地满足不同业务服务质量需求的优化路由协议.首先建立网络模型和优化分析,定义了链路度量和路径度量指标,路由协议选择端到端时延最小的路径,最大化网络吞吐量.然后提出了子频段和路径联合优化选择算法,对实时业务优先选择带宽抖动小和切换时延小的子频段及下一跳;对尽力传递业务优先选择带宽大的子频段及下一跳.最后提出频谱自觉的路由维护,通过局部频谱调整算法稳定路径不变,保证业务服务质量.仿真结果表明:该路由协议能满足业务服务质量需求,优化网络资源使用,减少数据包丢失,提高网络吞吐量. Based on the dependencies between routing and spectrum management, an optimized routing protocol is proposed to meet the service quality requirements of different services consciously in the spectrum.Firstly, the network model and optimization analysis are established, and the link metrics and path metrics are defined. The path with the least delay and maximizing the throughput of the network.And then proposed the joint optimization of sub-band and path selection algorithm, giving priority to real-time traffic with small bandwidth jitter and switching delay smaller sub-band and next hop; The subband and the next hop with larger bandwidth are chosen firstly.Finally, the conscious maintenance of the spectrum is proposed and the stability of the service path is guaranteed by the local spectrum adjustment algorithm.The simulation results show that the routing protocol can meet the requirements of service quality and optimize The use of network resources to reduce packet loss, improve network throughput.
