There are no offices today without computers, printers and other IT equipment. Enterprises keep contact with their clients and partners via reliable communication channels. These requirements must be fulfilled by a well designed IT network, as a system framework, wich has a dedicated internet connection.
This paper studies the design and construction processes of a concrete IT network. This was not a „greenfield investment,” but rather the reconstruction and modernization of an existing one, where both spending restrictions and the building’s physical structure posed limitations.
I will introduce the needs assessment process that shaped the general network requirements, and, later, the specific solutions, based on the client’s input. I will expose the aspects of cable type selection, how the building’s internal cabling was planned, and how the number of endpoints was determined. I will describe the design process of the logical and physical structure of the network, and the aspects of selecting the right active and passive equipment for the system. I will analyze the applied technologies, and I will explain the settings of the systems installed on the servers to meet client requirements. I will introduce how the VoIP system works (installed by an external supplier), and the prerequisites towards that system. I will also show how the public wifi network was established, and how an evolving problem with that network was eventually solved. I will talk about the training of the client’s employees, and, finally, I will examine whether the system meets the client’s initial needs and requirements.
Even though this paper deals with the development of one concrete system, it can serve as a guide to design similar projects.
