Multi-path chunked video exchanges over OF@TEIN SDN cloud playground

Abstract

Recent explosion of SDN (software-defined networking) paradigm is steadily facilitating the open evolution of legacy protocol-biased networking. In this paper, we design and develop middle-box splitting functionalities for chunked video exchanges (i.e., file transfer and streaming) over multiple concurrent paths over South Korea, Malaysia, and Thailand parts of OF@TEIN SDN-Cloud playground. To reduce middle-box processing delay and to enable multi-path capacity leverage, we propose to combine the multi-path file-transfer function and Tsunami protocol. This combination allows the multi-path-based pre-fetch transfer of 4K-video chunks from Tsunami server in South Korea to Thailand's SmartXBox. The experiment results show that the proposed scheme can reduce 23~72 seconds in transferring 10-minute 4K-video file by effectively utilizing the available international multi-path capacity.
