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 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 ...

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 ...

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 ...

Layers 7 through 4 are geared more to the application than the lower layers, which are designed to move packets from one place to another no matter what they contain. This top layer defines the ...

Network security is typically done in layers. Whether folks secure at the edge, the core, or in between, the network is secured in layers to ensure optimum protection. Using that as a baseline, author ...

As cybersecurity threats grow more sophisticated, traditional network architectures struggle to keep pace, especially in sectors reliant on legacy hardware. IMPRES Technology Solutions has introduced ...

We recently advised that people in the business of planning, building and supporting computer networks should not lose sight of the mythical OSI Layer 8. We define Layer 8 as the human-to-human ...

For many in the communication industry, the open system interconnect (OSI) network model is a simply a stack. But, designers shouldn't be so quick to diminish the value that the OSI model provides to ...
