Considerando lo anterior, en este trabajo de Título se ha planteado como objetivo general, el diseñar e implementar una plataforma de servicios de vídeo y televisión, a través del protocolo de Internet, por medio del cual sea factible ofrecer distintas aplicaciones de similares características a las obtenidas actualmente de compañías cinematográficas y televisivas, como lo son el tener una programación agendada, una transmisión en vivo y una -disponible- bajo demanda, que sea de carácter económica y con proyecciones educacionales.

My thesis deals with the Multicast transfer in IP networks and it describes distribution technology of packets with special focus on Multicast technology. The thesis is devoted to the principles of Multicast including the description of scheme, protocol Multicast distribution, registration in the Multicast groups and finally the advantages and disadvantages of the Multicast transfer. Further in the thesis is described in details the Source Specific Multicast technology (SSM) that comes from multicast. There is a description how this technology Works and its implementation in the network equipment including the user side. This part of the thesis also deals with so called Distribution Trees that are used as multicast distribution via the IP networks like for example Internet. Based on the knowledge of the Multicast was created the network to spread the multimedia data with support of Multicast and SSM. The network is designed based on the Cisco system equipment as is: Cisco Content Engine 566, Cisco IP/TV broadcast server and router 1812. This multimedia network provides many services including the live TV broadcast and video channels. In this network using the multicast distribution of packets was done an analysis by protocol analyzer unit WIreshark and Finisar. This protocol analyzer unit allows us to compare the efficiency of multimedia data transfer between the Unicast, Multicast and SSM.

This work deals with a monitoring application for multicast sessions. The general aim is to develop the application for monitoring multicast sessions from network elements of a laboratory computer network. The first part describes possibilities of monitoring computer networks in terms of monitoring techniques and protocols. The second part contains a topology of the laboratory computer network and several basic commands for setting of the multicast in Cisco IOS. The third part is devoted to the developed application for monitoring the multicast in Java language. The last part describes the testing on an actual multicast network and an example of such testing is stated there.
