I need urgent support with Ethereum Networking. A potential enterprise client is asking about the networking of Ethereum Node Peering. We have given them a lot of information about RLPx protocol and how it rides in Transport Layer being TCP based (Layer 4 of the 7 Layer OSI Model). However, the question being asked is “Explain/Describe how the connectivity between 2 peers works across each of the 7 layers of the OSI Model”. Can any one please help with an article or diagram? We can’t find anything covering this particular question.
