The Data Link Layer is one of my favorite layers of the OSI Model. Like a father who loves ALL of his children equally, but in different ways, I also love the other layers, but Layer 2 will always ...

The Open System Interconnect (OSI) network model, referred to by many as simply a stack, is in fact a well-designed, layered architecture for efficient intersystem and intrasystem communications. In ...

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 ...

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.

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.

Nonetheless, the OSI model was born from a theoretical perspective, and despite its precision in encapsulating how a network functions, it ended up relinquishing the practical ground to new ...

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 ...

As a matter of fact, when I started writing this post I titled it “Layer 4 of the OSI Model – understanding the application layer,” and then I had to go back and correct myself.

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 ...

CSOI represents a forward-thinking shift in network security architecture. By introducing an identity-aware layer into the OSI model, it lets organizations, especially those reliant on legacy systems, ...
