Abstract

The evolution of communications makes it possible to think of improvements in important topics of human development such as teaching and learning, surpassing borders and distances, to take a step forward and enter the world of distance education, in Where it is possible for a user on his / her work computer to receive at the same instant as it is generated, a paper, tutor, etc. It can even interact directly with the coordinator or with the other users who are simultaneously connected to the same event, getting as close as possible to a classroom of the commonly known. In this first part we will study the basic idea of ​​what multicast transmission is through the network, as well as everything related to the existing tools for this type of transmission such as, Mbone tools, CusseMe. Within the tools Mbone will analyze each of its modules and functions that comprise it, such as: RAT (Robusted Audio Tool), VIC (Video Integrate Conference), WB (WhiteBoard), which are integrated into a main module called RELATE. In addition, reference is also made to the protocols and methods for accessing the multicast flow through the network, from a host and how to send it or how to produce it from a server. Another important part is the analysis of the current system of Virtual Classrooms that is established in The UTPL, to be clear its operation and to determine its virtues and disadvantages, in such a way that we can fit properly the idea of ​​Multicast. Given this, you have the possibility to cover the shortcomings by adapting them to new tools that can meet the needs of the users that participate in this system of Virtual Classrooms of the UTPL.
