I am a student and my professor has assigned a paper on the OSI layers 6(Presentation) & 5(Session). Specifically, How each deals with Data in Motion with reference to Ethernet & OC's. I have been unable to find any information supporting a relationship between Layers 6 & 5 and the Ethernet/OCs. I am looking for help locating any information in support of such a relationship or confirmation that Ethernet/OCs are Layer 2 & 1 concerns not Layer 6 & 5. Thanks for any guidance that can be provided.
