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 IIoT is at the basis of the so-called Smart Factories, new advanced manufacturing units of the fourth industrial revolution. Smart sensors, super-fast connections, artificial intelligence ...

Network protocols define the rules for data formatting, addressing, error handling, sequencing, and flow control. This ...

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 ...

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 ...

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 ...

A couple posts ago, we talked about Layer 1 of the OSI Model — the Physical Layer. Today, we’ll start our climb up the Model with a visit to Layer 2, the Data Link Layer. The Data Link Layer is one of ...
