Before there can be a proper network architecture and design, the first step that needs to be taken is network architecture analysis. You cannot go into network design, or even network architecture without first knowing what is needed, hence the analysis stage. You should also be aware that one cannot exist without the others, since these three – analysis, architecture, and design – are three links to a single chain.
What does network analysis entail and why is it the crucial first step in this series of processes? It begins with the examining of the current system being used, and this step includes the finding out what problems there are with the current system, and what requirements all users may require. This will include descriptions of a lot of things like what the current network problems are, and what requirements people have.
A network analysis will also include descriptions of current traffic flows, maps of how various devices and applications are connected to the network, and what risks the current system has. Once the present system has been analyzed, objectives and problem statements regarding the new network will be made. This will help in narrowing down issues that may come up, and will also assist in putting together the right architecture and design for the business.
Importance of Analysis for Architecture and Design
The reason why an analysis of the past system as well as the proposed incoming one is required is because of its importance to the development of the architecture and design of the new system. Network architecture, after all, utilizes the information that is garnered from network analysis. The information is used to create the end-to-end structure and network concept for the proposed new network.
When the network architecture is being developed with the help of this first step, you can be sure that everything from network management, to routing, to security, to performance will be looked into and addressed. Optimization will also be part of the plan for the new network when such an analysis is enacted. This means that not only will you be able to find out what is wrong with the current set-up, but you will also be able to find solutions for similar issues or altogether avoid these with your new architecture and design.
The analysis of both the present and the future system will enable your company to find out which designs can work best for you. It will outline technology and topology options that will be ideal for your very specific requirements. It can also help you decide on how your layout will look, what type of equipment should be chosen over others, what configurations your company should opt for, and even who to choose when it comes to service providers.
These decisions cannot be made intelligently without a network architecture analysis. This first step is what will help you see what mistakes were made in the previous set-up, and what mistakes to avoid in the upcoming design. This will also help you make key decisions regarding what people need and what your company requires to get things done the right way.
