Abstract: 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.
