Except IPv6 performance on Malaysia youtube streaming.

What can I say....right after 11AM.....50kb/s



For the 10 5 or 8 seconds before clock strikes 11:00AM...I got 400KB/S.....then 50KB/s......


EDIT2:
That it ....everyone with 50KB/s IPV6 youtube throttling should send feedback together with CDN info.

First, visit https://redirector.googlevideo.com/report_mapping to find out your assigned CDN.

Then visit youtube website, scroll down to bottom and click 'Send Feedback'


Make a feedback on Malaysia youtube CDN server with explicit mention of IPv6 slowdown to 50KB/s during 11AM to 1AM.
EDIT3: Make sure write that you are TM Streamyx subscribers.

The more people complain about this to youtube.......the better.
Do realize this 'throttling' session has been happening since 2013.

For my case is opposite, if with ipv4 certain video cant play properly, keep buffering, but with ipv6 all videos can play without buffering 24/7.

IPv6 disable, buffering
.

IPv6 enable, playing smoothly

Hahahaah!!!

We have more users who have absolutely no problems with using IPv6.

Look at my poll results.

When I was on Streamyx, I do have a lot of problem with IpV6. When I contacted the customer support, they asked me to try to disable IpV6. And true enough all problems goes away...


I moved to Unifi, at first IpV6 isn't much of a problem... but as time goes, it starts to slowing down, not sure what happen I went on to disabled the IpV6 and everything works wonders again.

I start to wonder if the issues is router related.

Unifi users seem to have 'better' CDN allocated to them.
So, based on https://redirector.googlevideo.com/report_mapping , what are CDNs allocated to both of you?

My results are:-

2001:e68:5428:4652:eda3:9781:99bf:a3c1 => kul01s05 : router: "pr02.kul06" next_hop_address: "2001:4860:1:1:0:12b4:0:d" (2001:e68:5400::/42)


My Youtube streams smoother than butter.

Here's mine

2001:e68:5439:6b40:c424:8a1:5e53:1f1 => kul01s05 : router: "pr02.kul06" next_hop_address: "2001:4860:1:1:0:12b4:0:21" (2001:e68:5400::/42)

1 more thing i notice with IPv6, IPv6 play youtube video instantly once click the video link, but with IPv4, it will load around 1-2 second then only play the video.

kul01s05 : router: "pr02.kul01" next_hop_address: "127.0.0.1" (2001:e68:4000::/36)

See...both of you unifi users got kul06, streamyx users only get kul01.

Not to mention prefix 42......streamyx youtube CDN only has 36 prefix.

Weird part is why streamyx youtube cdn got extra hop to loopback 127.0.0.1

So, can we conclude that Unifi users have absolutely no problems with IPv6?

Yes. Unifi --> No problem with IPv6 when streaming youtube.

Unfortunately for streamyx users....... ........

I think it is router's problem. I am a UniFi, Streamyx, Maxis Fiber & TIME Fiber user. UniFi and Streamyx has problem with their IPV6 but after changing the router, my UniFi and Streamyx has no problem with IPV6. Time Fiber has no problem with their IPV6 but sadly, Maxis Fiber doesnt support IPV6 yet. If you want to use IPV6 on Maxis Fiber, you have to use tunnel broker.

I doubt it is router/modem issue. It is time specific throttling.
I got Dlink, TPlink, Asus and Aztech (2012 - 2015)

With Dlink free dynamic DNS bundle (CCTV usage) , I setup hurricane electric ipv6 tunnel and voila.......turbo 400KB/s from some America based youtube CDN.
Although I prefer not to use tunnel broker stuff due to some privacy concern. Not to mention it added some latency.....

I believe you.

You have done your research well.

Ya. Tunnel Broker does add some latency, that's why I don't really like it. You can use the dlinkddns.com account on other router. I created a dlinkddns account for my DVR with P1. Not willing to pay dyndns. Haha

But why TM provides lousy router which may affect the user experience when using IPV6?

Bundled free dlinkddns is linked to DLINK MAC addresses now, can't use it on other router.......technically I can.....telnet/ssh into the router and use 'macchanger -m XX:XX:XX:XX:XX:XX interface' , it works.....and editing/adding the profile of available dynamic dns list......

The older version of TM lousy router doesn't clamp TCPMSS to PMTU.

Quoting wikipedia:
IPv6 routers do not support fragmentation or the Don't Fragment option. For IPv6, Path MTU Discovery works by initially assuming the path MTU is the same as the MTU on the link layer interface where the traffic originates. Then, similar to IPv4, any device along the path whose MTU is smaller than the packet will drop the packet and send back an ICMPv6 Packet Too Big (Type 2) message containing its MTU, allowing the source host to reduce its Path MTU appropriately. The process is repeated until the MTU is small enough to traverse the entire path without fragmentation.

i am using dlinkddns on my Tp-link router. Work fine. I create the account when i got the Dir-850L from TM few months ago.

I'll just wait until my DNS proxy service supports IPV6.

U are on IPV6!. TQ for participating the test.
