Getting a handle on the invisible part of your network—the protocols that are in use—can be of enormous value in helping you detect problems. So far, we've talked about the tangibles of your ...

The third layer of the OSI Model, the network layer, is where most network engineers focus their time and expertise. As Darragh commented in my post on the data link layer, Layer 2 is cool but Layer 3 ...

The OSI model defines protocols for how a network technically handles communications at the various functional layers. Starting with electrons and photons at the physical layer (Layer 1), the model ...

If you have anything to do with networked AV and you're not well-versed in the OSI model, we've got you covered. You will learn the fundamental ideas around getting data from host A to host B over a ...
