Historically, the development of technology in the 18th and 19th centuries is considered as development of the great mechanical systems accompanied by the Industrial Revolution. The last two centuries, technologies have been developed in terms of information gathering, processing and distributing. In this direction are developed technologies in the areas of telephony, the invention of radio and television, the birth of the computer industry and communication systems. As a result of the rapid development of these technologies it has been achieved the unified look of the data distributions independently in which technology they are applied.
As the capabilities of collecting, processing and distributing of information grow, the need for more sophisticated information processing grows. Nowadays, it is impossible to do this without creating and using a computer network.
Prior to occur PCs, minicomputers were centralized so that the central computer stores and processes the data and the terminals just read and enter data. This in a way was a sort of computer network.
With the advent of personal computers in the eighties, now users of these computers are standalone so they could not cooperate and share resources. Hence the need arises and begins to develop hardware and software technologies for each electronic connection to PC, which is a computer network. The development of the hardware and software part of a network continues today.
To create a computer network there are used different media for connecting and different devices with different capacity and different prices. There isn’t a methodology for planning and modeling a computer network in a region. This methodology should bear in mind two parameters: a) the network that is designed should meet the needs of customers, and b) the cost of the network needs to be in the limits of the optimum. To design such a proper WAN in one region and possess these two properties is not a simple thing so this issue is still the subject of scientific circles.
The most important stages in the process of designing a computer network in the wider geographical region include: definition of complete requirements, topological graph description, identification and calculation of relevant parameters
(ie traffic matrix), determining the shortest path between nodes, quantification of the effect in different levels of technological development of urban areas that are involved, the cost of technology, service and price.
In this dissertation, we argue that the values of these parameters differ for WAN networks in different regions, because their calculation depends directly on the data "on the ground" and they are: population (household type), the distance between settlements, network traffic density and the bandwidth that is available. Interactions between individuals and groups of users play an important role and must be taken into account by simple or composite indicators of socioeconomic status. We suggest entering a composite socioeconomic indicator (SEI) in modeling the costs of a network in a wider geographic area, such as linear sum of products of weights and several measures of socioeconomic status or level of education. The main reason for the identification and evaluation of these parameters is to develop a model that can meet the constraints imposed by potential users.
Keywords: WAN, traffic matrix, socioeconomic indicators (SEI), shortest path algorithm, network traffic density, bandwidth
