I like to think of the transport layer as the layer of the OSI Model that enables more interesting traffic. While we network engineers may love a lot of the simpler uses of the IP protocol and ...

According to the OSI Model, the session layer is where connections are established, managed, and torn down. For connection-oriented network protocols, understanding how the session layer works, and ...

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 ...

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 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 ...

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 ...

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 ...

Other tips in this series have examined the seven-layer OSI model from the perspective of security. Although security was not the No. 1 goal of the designers of the OSI model, the idea behind these ...

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 ...

Could anyone help find authoritative online sources and /or otherwise articulate on why it makes sense to go from the “top down” in the OST 7 -- layer model, instead of “bottom up”, when ...
