Establishing the physical position of a computer in the Internet
 Relovský, Josef ; Kubánková, Anna (referee) ; Komosný, Dan (advisor)
This master‘s thesis is formed as a part of the research project for whose analyse is used the worldwide experimental network called PlanetLab. The whole dilemma is engaged by IPTV technology. IPTV is a protocol that makes possible transfer data of a television content over the Internet to the end user. In the IPTV technology the server is a source. These data are presented as a video and audio signal (streem) which are required to deliver to the end users. Some structure, which presents alternate these computers´connection, has been established, because the technology making use of the big pretention is used. The most patent way between the source and the destination is found. My objective is design this structure in the pursuit. The principle of the signal ramification from one node to several nodes (in group) is called multicast. Rather said from one node to the set of nodes. In the IPTV is presented each one single program for one multicast group. The concrete end users (recipients) are members of one or several obtainable multicast groups. The switch between programs demands a change from one multicast group to other group. For an analyse is used the worldwide experimental network called PlanetLab. This network was created after the floatation of three American´s universities in 2002. Nowadays it takes in more than 800 nodes which are distributed over the world. The PlanetLab is used by multinational company such as the Intel or the Hewlett-Packard. It is created for the testing and the scientific scope. I make the scripts in the Linux for the formation of the interconnecting structure. The main item by the course of the unreeling is response time. I investigate it with a command called “ping”. Everything is created in the Linux because all nodes use the operation system Linux in PlanetLab. By the help of the command “ping” I take the active nodes and response times. According to the response time I make a distance vectors which are used for the finding a location in the face of the references points which were determined before. According to the similarity of these vectors is designated to what end point is put to the point.
