Resumo:
With the development of new computer network applications based on the TCP/IP family protocols, it arises the necessity of improvements in order to give an effective response to the new requirements. The studies and researches focused on TCP/IP networks try to adequate the new communication technologies, that make viable the fast and secure information transmission, and the offer of new services that demand, for example, the transportation of different media. For this, it has been investigated new mechanisms that can reduce the use of the bandwidth as much as possible. In this context, it has been developed
new forms of data transference for the computer network that lead to the denominated multicast traffic. This dissertation presents a study of multicast protocols regarding the routing forms. It is proposed the MPS (Multicast Protocol Simulator) developed to allow the performance
analysis of the multicast protocols MOSPF (Multicast Extensions Open Shortest Path First), CBT (Core Based Trees) and PIM-SM (Protocol Independent -Multicast - Sparce Mode). The results gotten in the simulation of these protocols make possible the analysis and choice
of the ones that best fit to the necessity of a specific TCP/IP network, according to its topology and the resources available to it.
