Problems solved by technology

For actual elastic optical network design planning and optimal operation, a single network performance index cannot fully reflect the overall performance of the network
Secondly, the state of the network at a certain moment cannot fully represent the state of the network as a whole
For example, at a certain moment, the resource utilization rate in the elastic optical network is high, but it cannot be judged that the network status is good, because the high resource utilization rate at this moment may be caused by the high service blocking rate
