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 ...

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 ...

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 ...

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 ...

We have now met the archenemy of networks, Mr. Murphy, as he cackles “What can go wrong, will,” in the introduction to failure modes and the discussion of failure modes at the physical and data link ...

We met Mr. Murphy, of “What can go wrong, will” infamy, in the introduction to failure modes and the discussion of failure modes at the foundation levels. Now we will learn his tricks on shared media ...

Ethernet has captured the bulk of networking implementation over the past several years. One reason for its success lies in its flexibility. Properly speaking, Ethernet only defines the physical layer ...

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 ...
