Abstract: The Internet is, amongst many things, a transport mechanism for an end-to-end ecosystem of content delivery amongst participating players. Competing interests also must co-operate to deliver acceptable quality. At each interchange between players there is a set of selfish interests and actions which may optimize for one player at the expense of another. Balances are still being sought as the Internet evolves, and these are leading to temporary arbitrage opportunities that may sometimes jeopardize the entire chain. Quality is affected by a chain of factors both technical and economic. The location of a quality impairment introduced in the chain is often poorly understood and difficult to measure, and many commonly assume it can only be the access network. Using aggregated data from six North American networks, this presentation examines how trusted benchmarks from Speedtest, Netflix, and YouTube, which seek to ‘normalize’ experience into simple, objective measures, have accuracy and depth challenges, as well as a tendency to focus subjectively on a single point in the network rather than looking more objectively at the entire data path.
