The only network you’re likely to use that actually follows the OSI model is the CAN bus inside a car. And that’s starting to get replaced by DoIP, which uses the IP model (link layer, internet layer, transport layer, application layer, note the lack of session & presentation layers and combination of the physical & data-link layers into the link layer).
…you don’t need your networking gear to support this in any way
Yeah, this is about 5 layers above that in the OSI model
