Redes de próxima geração: uma visão funcional

Abstract

Show a description of the convergence technologies, that if it initiated with the net of traditional telephony commuted by circuit, where served of base for the first convergent services. It is intended, also, to explain as it is the current scene of the Nets of Next Generation with reference the evolution to the nets, the convergence, the compatibility of the broadband versus mobility, in view of that the user is "a devorador" potential of width of band, for in such a way, the technological convergence will give itself through xTecnologias on IP, this monograph will show to aspects of the IPv6 protocol with regard to its perationalization and addressing. E still topical of the application of Open Architecture of Services since the operators study a form to open its "doors" for the suppliers, making partnerships with intention to increase the use of its resources. The user will present aspects of the implementation of an intelligent environment where does not go to be worried about the sophisticated devices of interconnection and the some types of nets. This work, also, intends to mostar some excellent topics that must be weighed for the diverse segments of the companies of telecommunications as: the necessities from final users, of the suppliers of services and the suppliers of nets. The following pages will present, still, considerações regarding suppliers and services with regard to profiles of users, models of business and terminals of access, as well as, aspects with relation to the technology of physical access, mobile access and fixed access wireless, and also, excellent topics on the Y.2001 Recommendation, that offers a general vision on net NGN, according to ITU-T. It intends to present excellent topics between the NGN and the X.200 recommendation, that if it relates to the Basic Model of Reference - OSI. E, considerações regarding service finally multimedia to be fit by net NGN, as well as, of the interoperabilidade between environments NGN and not NGN regarding the quality of service and a conclusion regarding that it was presented.
