Modelo conceptual para implementação de VoIP nas zonas rurais

Abstract

Since the beginnings of humanity, communication between people has always been present in its most diverse forms. These evolved over time and with technology and today Information and Communication Technologies (ICT) are the most effective way of disseminating information. However, in Mozambique, ICTs are not yet available to all citizens, with city dwellers being the most benefited. In this context, several initiatives are carried out to bring ICT to the rural environment, among which the Community Multimedia Center stands out, which take Radio, IT and Internet to rural areas, allowing their people to have access to these means of communication more accessible. This work brings added value to this initiative of the CMC's as it intends to extend the range of information technologies available in the areas where the centers exist with the introduction of Voice Over internet Protocol (VoIP) in the centers' computer networks. This technology is based on switching Internet Protocol (IP) datagrams, which allows voice to be transported in real time over computer networks. In this context, an assessment of the computer network infrastructure of the CMC's in Manhiça, Namaacha and Matola was carried out in order to establish a scenario for the implementation of this technology, having these centers as pilots. As in any other area of ​​development involving technology, architectural patterns1 have been used to facilitate and help in thinking and articulating what is intended to be built. A study on information systems architecture frameworks is carried out, focusing on TOGAF, Standard P1471 and Zachman's framework, culminating in the choice of the latter for the conception of the model in question. Finally, there is the model conceived according to Zachman's framework in which one of the artifacts is the system prototype that mirrors some of the features that the VolP technology offers.
