摘　　要：针对因资源分配不均匀导致网络吞吐量较低的问题,提出一种虚拟网络资源负载均衡分配数学建模方法.首先,设定资源负载分配的目标函数,计算服务器链路剩余资源与剩余带宽的最佳比例关系,根据计算结果进行虚拟网络资源映射;其次,利用计算能力率、通信率、路径能力和关联度等网络能力因子参数反映资源的负载均衡情况;最后,基于求得的虚拟网络节点能力指标,设置资源属性调度周期,引入公平因子,更新链路的吞吐量,得到虚拟网络资源负载均衡分配模型,并基于该模型实现资源负载均衡分配.实验结果表明,该方法有效改善了资源分配的均衡度,使网络吞吐量得到明显提升.Aiming at the problem of low network throughput caused by uneven resource allocation,we proposed a mathematical modeling method for virtual network resource load balancing allocation.Firstly,we set an objective function for resource load allocation,calculated the optimal ratio between remaining resources and remaining bandwidth of server links,and mapped virtual network resource based on the calculation results.Secondly,we used the network ability factor parameters such as computing power rate,communication rate,path capability,and correlation degree to reflect the load balancing situation of resources.Finally,based on the obtained virtual network node capability indicators,we set resource attribute scheduling cycles,introducd fairness factors,updated throughput of the link,obtained a virtual network resource load balancing allocation model,and achieved resource load balancing allocation based on this model.The experimental results show that the proposed method effectively improves the balance of resource allocation,resulting in a significant increase in network throughput.
