Acesso em:.http://www.repositorio.ufpa.br:8080/jspui/handle/2011/2036Recently, the Next Generation Network (NGN) have emerged as a viable alternative to merge the data, voice and video transmission over a single network, while maintaining reasonable standards for quality of service. However, despite the improvements brought by the NGN philosophy, many developing countries lack the infrastructure necessary to implement such technology. In this context, technologies such as DSL (Digital Subscriber Line) allows universal access to broadband, with reduced cost and time, when compared to others access networks. In many third world countries, DSL can be considered a broadband network of high capillarity, since it uses a combination of the existing telephony infrastructure and transmission technologies However, the DSL network needs to be widely understood, so that its main advantages are not outweighed by the inefficiency of the system. Therefore, the implementation of a planning policy to aid in this process, taking into account the current needs of applications (voice, video and data) is of major importance. This thesis presents an approach based on strategies to facilitate the planning of communication networks which, a priori, were not implemented to support triple play streams (a prerequisite, nowadays, for the current profile of Internet users). It will be shown that, from the use of actual measurements and probabilistic analysis, it is possible to enable the planning of communication networks, considering physical and software parameters, such as the transmission path, the influence of noise in the communication, the protocols used, and traffic of Triple Play (voice, video and data) applications.porAcesso AbertoNGN - Rede de próxima geraçãoDSL (Linhas digitais do assinante)Sistema de comunicação em banda largaJogada tripla (voz, vídeo e dados)QoS (Qualidade de serviço)NGN (Next generation network)DSL (Digital subscriber lines)Triple play (voice, audio and data)QoS (Quality of service)TeseCNPQ::CIENCIAS EXATAS E DA TERRA::CIENCIA DA COMPUTACAO::MATEMATICA DA COMPUTACAO::MODELOS ANALITICOS E DE SIMULACAO
