Understanding Protocols and the OSI Network Model 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.

In this two-part series, we'll provide a different view of the OSI model, showing how the layers are interconnected and what protocol services are available at each level. In Part 1, we'll provide a ...

The OSI model is a layered model that describes how information moves from an application running on one networked computer to an application running on another networked computer.

A lot of the network administrators I’ve met have never had to think much about Physical Layer networking. Many weren’t classically educated in electrical engineering and have learned about ...

The OSI model is supported by the majority of major network and computer vendors, large commercial entities, and governments. This makes it very attractive as the model for locking down the devices ...

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 ...

Open System Interconnection, a layered model for network transport and applications. For instance, the seventh layer in the OSI model—the Application layer—defines program to program communication, or ...

Layer 2 of the OSI model is where we find the Data Link Layer, which provides the mechanism by which data is transferred from node to node across a network. What makes this layer important is that ...

Software defined networks are, of course, already well-established, but there the target is really only the first three layers of the famous OSI 7-Layer network mode l – the physical, data-link and ...
