How do I calculate universal switching license resources of a VP9000 series MCU? (How do I convert between universal transcoding and universal switching resources)?

For a VP9000 series MCU, the universal transcoding and universal switching resources are converted using the continuous presence.
The license resource calculation formulas are as follows:
Number of forwarding ports = Number of 2 Mbit/s forwarding channels + Number of 4 Mbit/s forwarding channels + Number of 6 Mbit/s forwarding channels + Number of 8 Mbit/s forwarding channels
Bandwidth resources = Number of 2 Mbit/s forwarding channels + Number of 4 Mbit/s forwarding channels x 2 + Number of 6 Mbit/s forwarding channels x 3 + Number of 8 Mbit/s forwarding channels x 4
Total video resources (Number of 4CIF transcoding channels) = Continuous presence resources (4CIF codec resources)/2 + Transcoding resources (Number of 4CIF transcoding channels) = 1080p 30 fps four-pane channels x 5 x 4/2 + 1080p 30 fps transcoding channels x 4
