| Abstract: | The UHD (Ultra High Definition) live video is very sensitive with packet loss and jitter of traffic. However there are some packet loss risks in current packet network. So OTN (Optical Transmission Network) multicast, which is based on OTN hard pipe and cross copy technologies, is proposed to get better UHD video experience. We take a trial in real network and collect amount of data, then contrast analysis is done between OTN multicast solution and traditional one. At last we give a cost model and an initial estimate for the total network. |
