Özet:

Data and IP-telephone-based audio transmission in campus networks is usually performed on the same network infrastructure. In the network environment, two different traffic points are encountered. The first of these is the normal flow traffic that represents data and sound. The second is the background traffic, which is considered unwanted traffic and negatively affects IP-based audio packages. This, whether or not, causes delays, volatilities and ultimately results in package losses. In this study, the sound disturbing factors caused by network confusions and torrents were studied. Audio packages moved on the VLAN (Sanal network) defined on the network devices. Thus, the voice was provided to be transmitted in the campus network without interruption and in a better quality. While Iperf tool is used here for tests from point to point, OPNET simulation software was used to evaluate VLAN performance. Tests conducted in more than one unit of the campus show that the volatilities of sound packages remain within the range of 0-150 ms and the delays of sound packages remain within the range of 0-20 ms.
