I have designed a network as part of a school project. It is an Ethernet, pretty standard. A few hubs per floor, hits a router in the closet, backbone up to the equipment room etc. One of the prompts for some discussion is asking whether this is a layer 7 or a layer 5 network or both? Seems sort of ridiculous to me unless I am misunderstanding things. One does not set out to build a "layer 7 network" or a "layer 5 network" right? It is more of a conceptual model, the 5 layer model essentially combining the top three of the 7 layer model. Has anyone ever tried to order a network card and been asked to choose whether it is for a layer 5 or layer 7 network? I think not. "hello, tech support........yes........yes.......ok well you need to set the network dip switch to 7 layers instead of 5....yes...ok..please fill out a short survey?.....-click-"
I guess the answer could be both? or "depends on how you want to look at it".
