Understanding Network Models – The Cisco Network Design Model

This article focuses on another important network model, the Cisco hierarchical network design model. Very different that the OSI model, this model is used as the basis for designing Cisco networks for security and performance. The article provides an overview of the roles and responsibilities of each of the model’s 3 layers.

Understanding Network Models – The OSI Model

I have to assume that after reading the title to this week’s article you probably let out a low, discerning groan of displeasure. Of all the networking topics that I’ve ever taught, the OSI model is the one that will generate looks of angst and torture on the faces of students. Some simply tune out and play solitaire, while others shake their heads in the familiar “not this thing again”. Still others pretend that there’s no time like right now to catch a half-hour of shut-eye. One thing that has never happened is someone’s eyes lighting up and them shouting “I love the OSI model!”. The reason for this is simple. This is often the first thing that people are ever taught when it comes to networking, and it was probably explained in such a way that they didn’t understand it to begin with. A theoretical model is a terrible introduction to the world of networking. The good news for me is that most of you probably already have experience in the field, and will hopefully be able to appreciate how important network models really are.

Creating CRM-Based Budgeting And Forecasting Models

Budgeting-forecasting models are key diagnostic tools for management to decipher how changes in policies and decisions impact financial performance. Finance typically maintains these models, as their format is attuned to existing accounting systems and data. This natural fit makes it a well-established process that is used in all organizations that plan and evaluate performance via individual product/service categories.
In a CRM environment this process disintegrates. The assumptions and relationships on which conventional financial data sources and analytical methods are built become inadequate, because CRM requires a systems perspective instead of a component perspective.
