基于SDN与NFV的电力5G网络切片差异化资源分配方案

基于SDN与NFV技术框架,以满足电力多业务差异化需求为目标,设计了面向大规模采集类业务、低时延电力工控业务、移动大带宽巡检类业务等场景的电力5G网络切片方案;建立了从电力业务需求到网络切片通信、计算资源的映射模型,揭示了两者之间的作用机理与转换关系.以电力多业务传输带宽、时延以及计算资源需求为约束条件,建立了电力5G多业务网络切片运行经济性最优数学模型,提出网络切片通信与计算资源的联合分配算法,实现了电力网络切片资源高效、经济利用.

Differential resource allocation scheme for electric 5G network slices based on SDN and NFV

Based on the technical framework of SDN and NFV, the electrical 5G network slicing scheme was designed for the scenarios of large-scale acquisition service, low-delay power industrial control service, mobile large-bandwidth patrol service, etc., so as to meet the differentiated demands of electrical multiple services. The mapping model of electrical service demand onto communication and computing resources of network slices was established, and the mechanism and transformation between them are revealed. Constrained by the transmission bandwidth, time delay and computing resource demand of the electrical multiple services, the economical efficiency optimization problem of electric 5G multi-service network slice is formulated. A joint allocation algorithm of communication and computing resources is proposed to address the issue of efficient and economic resources utilization.
