I agree with you froix but it can provide an anlogy and can help to better understand the concept of layers.
Layer one is for switches and packets. Where did it come from and where is it going? This is one step up from a hub, where everybody talked to everybody else.
Layer two is for route processing. I know where the information is going and coming from, but now I want to find the fastest route there.

Layer three is for intelligent network services. I know which route, but now I care about what. This layer gives priority to Voice over IP or video to reduce and prevent dropouts. This layer is application-sensitive.
