Abstract:
Internet traffic nowadays is predominantly composed by video streaming. Moreover, most video streaming traffic is carried over Hypertext Transfer Protocol/Transmission Control Protocol (HTTP/TCP). Understanding TCP stack performance in transporting video streams has become paramount, specially in face of recent multipath transport protocol evolutions and multiple client device interfaces available. In this paper, we characterize path schedulers performance of streaming of video sessions over cellular and Wi-Fi access networks, the two most common and dominant wireless technologies in the market. We use network performance level as well as video quality level metrics to characterize multiple path schedulers and resulting network and application layers’ interactions.
