Abstract: A method and a system for automatic machine learning-based prediction of new energy power with cloud-edge collaboration are disclosed. The method includes: obtaining, in response to a power prediction demand for a target new energy station, future numerical weather prediction data of the target new energy station in a future period and historical output power of a historical period corresponding to the future period; selecting, based on missing of the future numerical weather prediction data and a data amount of the historical output power, a target power prediction model corresponding to the target new energy station; and adjusting the target power prediction model according to the target working mode, and predicting, by the adjusted target power prediction model, a target output power of the target new energy station in the future period, based on the future numerical weather prediction data and the historical output power.

Abstract: A method for forwarding a packet and a switch are provided. The switch receives a packet via a port; when the packet is a layer-2 packet, determines a VSI based on an ID of a MDC to which the port belongs and an ID of a VLAN of the packet, searches for a layer-2 entry stored in a chip where the port is located and matching with the VSI and a destination MAC address of the packet, and forwards the packet based on the layer-2 entry; when the packet is a layer-3 packet, determines a second VRF based on the ID of the MDC and an ID of a first VRF to which the packet belongs, searches for a layer-3 entry stored in the chip and matching with the second VRF and a destination IP address of the packet, and forwards the packet based on the layer-3 entry.
