Adaptive Bitrate Algorithms Cloud Final Project 2020

Will Ye, Simon Zeng, Jason Zhang

• We aim to investigate how adaptive bitrate algorithms work in video streaming systems.
• Based on Pensieve https://github.com/hongzimao/pensieve
• Look under /rl for the reinforcement learning component
• Look under /videoPlayer for our custom video player system

Remote Desktop Setup

• because of instance limitations for multiple validators, we decided to have a dedicated GCP instance for each validator. Because there is a video component to it, we also want the validators to be able to watch the video player. So we decided to go with NoMachine.
• NoMachine setup followed this set up video
• only extra configuration was with which default desktop command is run by nomachine. To set it, edit /usr/NX/etc/node.cfg on the GCP instance with an editor and change the DefaultDesktopCommand line to be DefaultDesktopCommand "gnome-session", or an equivalent command to run a desktop environment.
• refer to our VM instructions on how to download the NoMachine client and access the GCP via local machine
