基于在线双向拍卖的虚拟网络切片资源调度机制

Resource Scheduling Mechanism for Virtual Network Slice Based on Online Double Auction

为解决5G网络切片间资源分配的问题,该文提出一种基于在线双向拍卖(ODA)的资源调度机制。该机制首先针对不同的业务需求和业务收益确定网络切片的优先级和单位资源报价;其次明确最大化网络收益的目标建立线下单向拍卖模型;进一步,考虑资源的动态分配和回收利用,提出价格更新算法实时更新资源价格;最后,综合线下单向拍卖机制和价格动态变化机制建立在线双向拍卖模型,为切片动态分配资源。仿真结果表明,该机制在提高网络收益的同时可以保证各切片用户的QoS需求。

In order to solve the problem of resource allocation between 5G virtual network slice, a resource scheduling mechanism based on Online Double Auction （ODA） is proposed. Firstly, the priority of network slices and unit resource quotes are determined according to different traffic needs and traffic benefits. Then, to maximize the network revenue, an offline single auction model is established. Further, based on the resources dynamic allocation and recycling, the price-updating algorithm is proposed to update the resource price in real time. Finally, the offline single auction mechanism and the price update mechanism are combined to establish ODA model and allocate resources dynamieally for the network slices. The simulation results show that the proposed mechanism can improve network revenue and guarantee the QoS requirement of each slice user.
