Furthermore, YouTube will soon start pre-loading related video content, so that if you click on a suggested video, it is already there. These “tricks” might work well in a fixed environment, where start time is paramount and video traffic volume is not relevant, but in a wireless network that is congested; these types of features would have a negative impact on the network capacity and ultimately the user experience. I have before warned about content providers' tendency to design services and technology for fixed line first.
The protocol is starting to make its appearance in mobile networks and while not yet dominating the YouTube experience, it is a perfect example of why a video service designed for the internet, to be viewed on a fixed network can have catastrophic consequences on a mobile network if not correctly adapted. This is one of the many subjects I analyse in my report "Mobile video monetization and optimization 2014".
