Analysis Of The Dash Protocol Behavior In A Closed Network Environment

This article describes the behaviour of DASH adaptive streaming technology (which provides the ability to deliver streaming media content over the Internet using HTTP) in a closed network environment that can be replicated across the network. The experiment can be divided into two steps: at first, we set up a web server that hosts DASH files in the Google Cloud Virtual Machine. In the second step, we perform client-side network bandwidth (Regular 2G, Good 2G, Regular 3G, Good 3G, Regular 4G/LTE) changes and analyse the behaviour of the protocol: how Video Buffer, Video Bitrate and Video Latency are changing over time. As a result, based on the analysis and the data obtained, the advantages and disadvantages of DASH technology were identified, as well as which kind of im-pact has a 5% packets drop rate on the protocol in the short term.
