I'm creating a class describing how to access network traffic in order to conduct network security monitoring. I'd like to know if anyone would mind sharing photos of their network closets, with descriptions of the gear in the rack and their network diagram. I'm looking to learn how you get connectivity from your ISP, where that link goes, and what your core, distribution, and access layers look like. I don't need to know about your desktops or whatever. I really just want students to get a look at a network closet and the sorts of connectors, cables, and rack gear they might expect to find.
I will not name any names. I'd just like to provide some real-world photos for students. If you can help, please email your photos Friday, along with short descriptions of what's shown. Even pictures taken with camera phones are fine. Thank you very much!
