At Netflix, we found in quite a few networks IPv6 had much better QoE than IPv4. In a limited number of cases, IPv6 was very broken. It was almost always equal or better.
- divbzero 4y agoDid you have a sense of whether QoE diverged due to differences in the networking equipment or differences in the protocol itself?
- virtuallynathan 4y agoI believe in 1 case it was pathological issues with some networking equipment, but this was a recent thing, so I haven’t looked into everything yet.
- bombcar 4y agoThere's an awful lot of very old IPv4 equipment still hanging around, but most of the IPv6 stuff is newer - so if IPv6 is working it's probably a more recent piece of hardware.
- ev1 4y agoMuch smaller POV, but when I was dealing with ISP things in past I've found that on many networks v4 might have a nice, redundant blend while frequently v6 is some mix of HE+something or singlehomed HE, which disappoints me. But then the fact that their ports are basically unused other than for the usual G/YT/FB traffic makes the v6 pretty uncontended.
- liveoneggs 4y agoor when HE has bad/broken routes...
- virtuallynathan 4y agoLuckily we have embedded OCAs and/or peering with almost every network of significant size, so their choice of transit rarely comes into the mix.
