I chose The Analysis of YouTube protocols as my thesis title. YouTube is the world largest and most popular video sharing website. Anybody can upload video to this portal, even in an endless quantity. Firstly, I had to know this website. After that I had to know the protocols which were used by Youtube video sharing site. When I had enough information I made a work station in ntop programming language. I had to get measures with ntop program and with that I could create a database. With the help of ntop I exported the measured data into JSON file that I had to convert into a CSV file to be able to process it with Microsoft Excel. Here are some important measures: Rate of the protocols, The data which are going through protocols, The average download speed, The measuring of the video size within the protocols, The measuring of the video quality within the protocols. At last I analyzed the data which are going through the protocols, documented it fully and also I made some conclusion from them.
