The Differentiated Resource Allocation Scheme of Power 5G Network Slice Based on SDN and NFV

Based on the technical framework of SDN and NFV, aiming at meeting the differentiated demands of multiple power services, a power 5G network slicing scheme is designed for scenarios such as large-scale acquisition services, low-delay power industrial control services, and mobile large-bandwidth patrol services. The mapping model from power service demand to network slice communication and computing resources is established, and the mechanism and transformation relationship between them are revealed. Based on the constraints of power multi-service transmission bandwidth, delay and computing resource demand, an economic optimal mathematical model of power 5G multi-service network slice operation was established, and a joint allocation algorithm of network slice communication and computing resources was proposed to realize efficient and economic utilization of power network slice resources.
