Resources for learning networking for back end development

Hello everyone, I am a frontend developer and I am trying to shift to backend development. I am studying directly from Node JS docs but I have realised that most of their networking modules are hard to understand without have a knowledge of networking . So searched google for resources but didnt find a single resource. All resources were in depth covering those OSI layers that a backend developer would not need. So anyone please suggest me some resources(videos, books, articles anything) for studying networking but for a level of backend engineer.
