Previous issue date: 2004-12-10 / In the two last decades of the past century, following the consolidation of the Internet as the world-wide computer network, applications generating more robust data flows started to appear. The increasing use of videoconferencing stimulated the creation of a new form of point-to-multipoint transmission called IP Multicast. All companies working in the area of software and the hardware development for network videoconferencing have adjusted their products as well as developed new solutionsfor the use of multicast. However the configuration of such different solutions is not easy done, moreover when changes in the operational system are also requirede. Besides, the existing free tools have limited functions, and the current comercial solutions are heavily dependent on specific platforms. Along with the maturity of IP Multicast technology and with its inclusion in all the current operational systems, the object-oriented programming languages had developed classes able to handle multicast traflic. So, with the help of Java APIs for network, data bases and hipertext, it became possible to the develop an Integrated Environment able to handle multicast traffic, which is the major objective of this work. This document describes the implementation of the above mentioned environment, which provides many functions to use and manage multicast traffic, functions which existed only in a limited way and just in few tools, normally the comercial ones. This environment is useful to different kinds of users, so that it can be used by common users, who want to join multimedia Internet sessions, as well as more advenced users such engineers and network administrators who may need to monitor and handle multicast traffic / Nas duas ?ltimas d?cadas do s?culo passado, com a consolida??o da Internet como rede mundial de computadores, aplica??es de fluxos mais robustos come?aram a surgir. A crescente uso de videoconfer?ncias impulsionou a cria??o de uma forma de transmiss?o ponto-multiponto chamada Multicast IP. Todas as empresas que desenvolviam software e hardware para videoconfer?ncia adequaram seus produtos e criaram novas solu??es para o uso do fluxo multicast. Entretanto, a configura??o das diversas solu??es n?o ? trivial e, normalmente, altera??es no sistema operacional precisam ser realizadas. Al?m disso, ferramentas gratuitas apresentam funcionalidades limitadas, e as solu??es propriet?rias encontradas na atualidade s?o muito dependentes de plataformas espec?ficas. Com o amadurecimento da tecnologia Multicast IP e com sua inclus?o em todos os sistemas operacionais atuais, as linguagens de programa??o desenvolveram classes capazes de manipular tr?fego multicast. Com as APIs Java para redes, banco de dados e p?ginas Web, tornou-se poss?vel a cria??o de um Ambiente Integrado capaz de manipular tr?fego multicast, que se constitui na proposta central deste trabalho. Esse documento descreve ent?o a implementa??o deste ambiente que agrega diversas funcionalidades para utiliza??o e ger?ncia de tr?fego multicast, funcionalidades at? ent?o presentes de forma limitada em poucas e distintas ferramentas comummente propriet?rias. O ambiente se adequa a diferentes perfis de usu?rio, no sentido de que pode ser usado por leigos em Engenharia de Redes, que desejem apenas participar de sess?es de multim?dia na Internet, como tamb?m por especialistas e administradores de rede que desejem monitorar e manipular o tr?fego multicast
