The project for the graduate thesis is the performance of "IPTV", which is also the work simulation of internet-television on MikroTik equipment. The project was conducted in the premises of SOSS, in laboratory P08. The type of group communication used is "Multicast", which is best described as communication that works on the principle of subscribing to the desired programs, and the "IGMP" (Internet Group Management Protocol) is a used protocol that has an important role in directing traffic. Configuration was administered on MikroTik routers, Allied Telesis switches, and on computers that were available. The equipment was arranged in a way so that the servers, which broadcasted certain programs were physically separated from the recipient ie viewer. With the simulation there were shown three servers that broadcasted different types of programs, while the viewers in a physically separated locations chose what they wanted to watch. Besides the IPTV configuration, there will be an explanation for the allocation of "Rendezvous Point" (RP) in the paper.
