An Openflow-Based Architecture Of Scalable Video Multicast(Cont.) Media Server For example, the base layer of a video with V ID = video001 is sent at port 50016 in a server with IP address 10.0.0.10, while its enhancement layer 1 is transmitted at port 50017. Then, the OpenFlow switches can identify the base layer by the tuple (10.0.0.10, 50016), and the enhancement layer 1 by the tuple (10.0.0.10, 50017).
