Modelação do sistema de gestão de linhas dedicadas - caso Teledata

Abstract

In order to improve communications between different people, information technology developers have been concerned with serving their consumers better. Large organizations have equipped themselves with the most efficient technologies in order to respond to the competitive market in which society is involved. Teledata de Moçambique, Lda, is a telecommunications and information technology service integrator. Among the various products sold by Teledata we can highlight: application and server hosting, design and management of sites, data communication, and dedicated internet and VSAT. In terms of internet solutions, Teledata offers dial-up access and dedicated access, and in the area of data communication, Teledata develops solutions for the corporate market. Its solutions use frame relay and X.25 protocols. To ensure the provision of the services provided, Teledata has a switched data communication network that covers the whole country. The present work addresses the modeling of the Dedicated Line Management system using UML (Unified Modeling Language). Dedicated lines provide a permanent connection to the Internet from a computer or network of computers. The connection is permanent, so you do not have to incur costs for telephone usage. Dedicated line access service provides a connectivity solution at a fixed monthly cost, regardless of connection usage. UML is used in the development of many different types of systems. It always covers any feature of a system in one of its diagrams, and is also applied in the different phases of a system's development life cycle, from the requirements analysis specification to completion with the testing phase. The goal of UML is to describe any type of system in terms of object-oriented diagrams.
