摘要
当前超高宽5G电力无线网属于时间敏感网络,可以支持电力相关的敏感数据等多类型流量数据共同传输,通过全局规划调度不同类型数据,并在出端口消除冲突依次传输。虽然有超高带宽的保证,但是电力时间敏感数据流量调度与路由分离,导致不同流量下,时间敏感流量数据与非时间敏感流量数据调度中发生时隙争用,形成调度冲突。设计一种针对超高带宽5G电力无线专网通信的流量调度算法,利用抽样与两级CBF技术对超高带宽5G电力无线专网中的通信流量展开识别,以确定大小流。利用链路的最大剩余带宽、时延和丢包率作为评价指标来计算流量数据时间敏感性的综合评分。根据敏感性评分和数据流量大小,作为待选路径的原则,结合大小流的调度需求,采用优化的蚁群算法来选取最优路径,从而实现通信流量的调度。实验结果表明:该方法提高了超高带宽5G电力无线专网的对分带宽和链路利用率,并且降低了链路丢包率。整个电力网络的负载能力也得到了提高。
At present,the ultra high width 5G power wireless network is a time sensitive network,which can support the common transmission of multiple types of traffic data such as power related sensitive data,dispatch different types of data through global planning,and eliminate conflicts and transmit them in turn at the outgoing port.Although there is a guarantee of ultra-high bandwidth,the separation of power time sensitive data traffic scheduling and routing results in time slot contention between time sensitive traffic data and non time sensitive traffic data scheduling under different traffic conditions,resulting in scheduling conflicts.Design a traffic scheduling algorithm for ultra-high bandwidth 5G power wireless private network communication,using sampling and two-level CBF technology to identify the communication traffic in the ultra-high bandwidth 5G power wireless private network and determine the size of the traffic.Use the maximum remaining bandwidth,latency,and packet loss rate of the link as evaluation indicators to calculate the comprehensive score of traffic data time sensitivity.Based on sensitivity scores and data traffic size,as the principle of selecting the desired path,combined with the scheduling requirements of large and small flows,an optimized ant colony algorithm is used to select the optimal path,thereby achieving communication traffic scheduling.The experimental results show that this method improves the split bandwidth and link utilization of ultra-high bandwidth 5G power wireless private network,and reduces the link packet loss rate.The load capacity of the entire power network has also been improved.
