摘要
摘要:针对5G接入网络中虚拟网络功能(VNF)部署完成后，其资源需求发生动态变化，导致网络中物理机(PM)资源利用率过高或过低这一问题，该文首先将网络中PM的资源使用情况划分5个不同分区，提出一种多优先级VNF迁移请求队列调度模型。其次基于该模型，对VNF迁移开销的最小化及网络能耗的最小化建立联合优化模型。最后提出一种基于5G接入网络的多优先级VNF迁移开销与网络能耗联合优化算法对其进行求解。仿真结果表明，该算法在有效实现VNF迁移开销与网络能耗折中的同时，提高了PM资源利用率，保证了PM性能并均衡各PM负载。

Abstract:After the Virtual Network Function (VNF) in the 5G access network is deployed, the resource requirements are dynamically changed, resulting in the problem that the Physical Machine (PM) resource utilization in the network is too high or too low. To solve the above problem, the resource usage of PM in the network is divided into five different partitions, and a multi-priority VNF migration request queue scheduling model is proposed. Secondly, based on the model, a joint optimization model is established to minimize the VNF migration cost and minimize the network energy consumption. Finally, a multi-priority VNF migration cost and network energy joint optimization algorithm based on 5G access network is presented to solve the above model. The simulation results show that the algorithm can effectively improve the PM resources utilization, ensure the PM performance and balance the PM load while effectively realizing a compromise between VNF migration cost and network energy consumption.
