Dynamic resource orchestration mechanism for power communication network based on NFV-SFC

The high proportion of new energy sources integration causes issues such as load imbalance and high complexity in resource management. Low resource utilization has emerged in the power communication network. It is urgent to provide unified scheduling and on-demand resource allocation. Hence, the dynamic resource orchestration mechanism for a power communication network is studied based on NFV-SFC. First, the resource orchestration architecture based on NFV-SFC is constructed to complete the scheduling of virtual network functions. An NFV-SFC-based dynamic resource orchestration model is established to evaluate the performance of dynamic resource configuration and a dynamic resource orchestration mechanism based on a simulated annealing algorithm is proposed. Numerical results show the algorithm's effectiveness.
