Abstract

This thesis describes how the internet network infrastructure in a small ISP (internet service provider) can be changed to fulfill the requirements of the Electronic Communications Act which was adopted in 2007 by the Slovenian parliament. To simplify the process, we created a programme that changes client's reception device. The programme is written in C\# language. Its advantage is that we do not need to manually change the settings of each client's reception device. Instead, we type into the programme the IP addresses of reception devices, along with desired preferences. The programme then accesses each device via the IP address and changes the settings. Since it was created for client's recipient devices only, other network router's settings need to be adjusted manually. First, we changed the settings of the main router that is connected to the network with an optical line. Second, we changed the routers on transmitters. We proceeded by changing the client's reception devices using the programme that we wrote. The settings of users connected to the same transmitting device on the transmitter were being changed simultaneously. Last, we changed the transmition device. We repeated the process until all transmitters were changed. What we found out was that after the change the network speed and security improved. Connections between transmitting and receiving devices were secured using WPA2 protection. Network devices are now being accessed through HTTPS links. And the network infrastructure itself became simpler, which exhibits in a smaller number of errors.
