Fwd: measuring youtube over v6

---------- Forwarded message ---------- From: Vaibhav Bajpai <bajpaiv(a)in.tum.de> Date: Wed, Jul 5, 2017 at 11:50 PM Subject: measuring youtube over v6 To: Vaibhav Bajpai <bajpaiv(a)in.tum.de> Dear v6 hosts, Do users experience benefit (or suffer) from streaming YouTube videos over IPv6? ------------------------------------------------------------ -------------------- To answer this question, we developed a youtube test that measures YouTube content delivery over IPv4 and IPv6. We deployed this test on ∼100 SamKnows probes. A paper analysing this ~3 years long dataset ('14 - '17) just came online. Thought to share it along: http://vaibhavbajpai.com/documents/papers/proceedings/youtube-ccr-2017.pdf We will present this at the IETF on Thursday. Please do come to the talk: https://datatracker.ietf.org/meeting/99/agenda/maprg Feedback most welcome and thanks for keeping the probe online! :-) Abstract -------- We measure YouTube content delivery over IPv6 using ∼100 SamKnows probes connected to dual-stacked networks representing 66 different origin ASes. Using a 34-months long (Aug 2014-Jun 2017) dataset, we show that success rates of streaming a stall-free ver- sion of a video over IPv6 have improved over time. We show that a Happy Eyeballs (HE) race during initial TCP connection estab- lishment leads to a strong (more than 97%) preference over IPv6. However, even though clients prefer streaming videos over IPv6, we observe worse performance over IPv6 than over IPv4. We witness consistently higher TCP connection establishment times and startup delays (∼100 ms or more) over IPv6. We also observe consistently lower achieved throughput both for audio and video over IPv6. We observe less than 1% stall rates over both address families. Due to lower stall rates, bitrates that can be reliably streamed over both address families are comparable. However, in situations, where a stall does occur, 80% of the samples experience higher stall durations that are at least 1s longer over IPv6 and have not reduced over time. The worse performance over IPv6 is due to the disparity in the availability of Google Global Caches (GGC) over IPv6. The mea- surements performed in this work using the youtube test and the entire dataset is made available to the measurement community. -- Vaibhav -------------------------- Vaibhav Bajpai www.vaibhavbajpai.com Postdoctoral Researcher TU Munich, Germany --------------------------
