Media Server
For example, the
base layer of a video with V ID = video001 is sent at
port in a server with IP address , while
its enhancement layer 1 is transmitted at port
Then, the OpenFlow switches can identify the base layer
by the tuple ( , 50016), and the enhancement
layer 1 by the tuple ( , 50017).
