Abstract(s)
Numa constante tentativa de replicar localmente os casos de sucesso das sociedades mais avançadas, as sociedades modernas de tudo têm feito para melhorar a qualidade de vida das suas comunidades. A par desta circunstância, o mundo educacional tudo tem feito com o objetivo de manter linear o acesso a informação, independentemente do local ou do horário, e para isso, têm sido colocados muitos recursos na disponibilização do acesso à Internet. A dissertação apresentada centra-se na investigação e desenho da extensão da rede académica angolana ao serviço Eduroam, por esta ser uma rede de dimensão mundial que contribui fortemente para a mobilidade e melhoria da qualidade de vida das comunidades académicas. O levantamento do estado da rede académica angolana, o estudo e definição de um mapa que promova a instalação de uma rede pan-académica, bem como os mecanismos para a ligação da mesma na rede Eduroam foram tidos em conta. Os servidores RADIUS são o padrão da implementação do serviço Eduroam, pois, a GÉANT como equipa gestora líder deste serviço, mantém uma hierarquia de servidores RADIUS para o funcionamento adequado do serviço, permitindo o encaminhamento e resposta de solicitações por via desta hierarquia quando os utilizadores do serviço estão em mobilidade. No caso desta dissertação, optou-se por usar o FreeRADIUS, uma plataforma que é compatível com RADIUS e também usada em vários pontos da rede Eduroam, por ser opensource e flexível na configuração. A disponibilização do serviço para utilizadores internos com a autenticação no servidor Identity Provider local, bem como, o acesso a rede por parte de utilizadores externos via servidor proxy, foram testados e validados, de modo a garantir acesso à rede a quando da mobilidade dos mesmos.
In a constant attempt to replicate at a local level the cases of success of more advanced societies, modern societies have excelled in attempts to improve the quality of life of their communities. Accompanying these efforts, academia has also gone the length to keep the access to information in an effortless manner, regardless of time and place, and for this, a significant amount of resources have been committed to provide access to the Internet. This dissertation is focused on the research and design of the extension of the academic network of Angola to the Eduroam service, as this is a world-wide network that strongly contributes to the mobility of the academia and to the increase of the quality of life of its members. The identification of the status of the Angolan academic network, the study and definition of a roadmap that promotes the connection of the Angolan academic network to Eduroam, as well the study of all the required mechanisms were taken into consideration. RADIUS servers are the standard for Eduroam, as the management team of this service, GÉANT, maintains a hierarchy of RADIUS servers to support the routing and response of solicitations from users that are in mobility. In the case of this research, the FreeRADIUS software was used, because this is compatible with RADIUS, it’s used in several points of the Eduroam network and it’s open source and very flexible in its configuration. The availability of the service in the deployed testbed, both to internal and mobility users was achieved. The internal users were authenticated via the local Identity Provider server, while the mobility users were authenticated via the proxy server. Conclusions are presented to deploy the Eduroam service in the academic network in Angola.
