This work presents a quantitative experimental study of multicast video traffic in a Wi-Fi network of a real laboratory as test bed, with a topology in wired and wireless networks with wireless clients working in the IEEE 802.11ac standard. For experimental work IPv6, the Server and Client Software FFmpeg and the traffic analyzer WireShark were used. The videos were encoded in H.264, H.265, VP8 and Theora, to assess and understand the impact of different codecs on network traffic. And the experiments were carried out using a trailer of the movie Star Trek, and alternately for contrast, a video of a videoconference using Adobe Connect, of the same duration and resolution. This work is a continuation of experience made on wired networks for video traffic with codecs H261, H263 and H264 using IPv4. Although this work presents a new scenario of Wi-Fi experimentation and a new methodology for the contrast of videos using IPv6. |
