Emulated OpenFlow Based Experimental Study on Middle-Box Buffering Effect for Multi-Path Chunked Video Streaming

In this paper, we have implemented the emulated multipath OpenFlow network with splitting and middle-box functionalities for investigating video buffering effects on packet delay and jitter performance for an RTP video streaming session. The mininet emulator is used to construct the multi-path OpenFlow network. The network consists of a video server, a video client, four Open vSwitches (OVSs), a remote controller and a middle-box. The POX controller is used for adding flow entries into switches and assigning periodic splitting function. The reported mean/ standard deviation of packet delay results show that the proper chunk size ratio and initial buffering time need to be considered carefully to improve the video packet delay and jitter performance.
