Re: [nznog] Comcom/Samknows broadband testing from a different perspective

Bringing this conversation back on list, Jason is accessing the M-Lab servers via Spark. I would expect the performance through Spark to be poorer as they don't peer in NZ. Instead, we're exchanging traffic with them in Sydney. We have reminded Spark that we're on the various peering exchanges and we are of course happy to accept their routes from the route servers.

Do you know which node (AKL vs WLG) you're talking to or it's IP address?

If not, can you flick me your address off list and I'll dig through the flow records and try and figure it out.

The reason I ask is I'd like to see a traceroute to/from your address to see the path the traffic is taking.

We have 10 Gbps ports on APE/AKL-IX, but only 1 Gbps on WIX/CHIX. Since the testing started we've started seeing discards on our WIX port during the evening which I'm pretty sure is being driven by the testing traffic. We've ordered an upgrade to 10 Gbps which I expect to get live in the next couple of weeks. This could explain the download test struggling to get close to 1 Gbps, but I think it less likely to impact the upload test.

Thanks,

Dylan

Hi

Since putting the device on the Enable Network, I’m actually not overall happy with the results I'm seeing.

There is an inconsistency with the Download/Upload Speed, Latency and Jitter.

When testing using another Testing service such as Speedtest.net and Fast.com, Iperf are consistently report my connection speed as 950Mb/s Downstream and 500Mb/s upstream.

Samknows is reporting this My peak connection Speed for download of 742Mbp/s and upload 429Mbps, but these results are not consistent when I compare other speedtest services.

According to the data provided from Samknows user analytics, they are testing the download speed on the hour between 6 pm and 11 am daily and one sample at 5 am. These times represent Enable network peak and off periods for traffic.

- The graph below are taken over a 7days period, sampling every 30 seconds at a bit per second. - Have another member of NZNOC got similar testing results to mine - What I can’t answer is how the data in the graphs below is represented by Samknows.

Note:

The Samknows device is the only (Connection) plugged into this GPON interface.

There is other user traffic been generated on this port other than samknows device.

OpenWRT/LEDE binary, Just shell on.. opkg update, -i what you need..., netstat -antop | grep EST this will surprise you, dest will surprise you more then I put in the green wheely. On the WAN link you may see lots of src privates indicating typical dinky rtr/fw nat not coping similarly actual/true $paid for bandwidth at src (home) = rubbish + legit flows. rubbish flows (in/out) of breaks packet concurrency increasing delays and maxin out (netflix/gaming stream) PDVs on clients - recommend filter|block upstream of router will lead to a huge improvement in media quality and performance of your home router.

There is a Geekzone thread that I kicked off when I attended the Commerce Commission presentation about Samknows and got to meet Sam.

https://www.geekzone.co.nz/forums.asp?forumid=49&topicid=237852

I've done a bit of analysis on the traffic but haven't dug too deep yet as I didn't want to bust open the box and try and reverse engineer their OpenWRT build.

Happy to put anyone in touch with the guys I have dealt with directly from the Comcom and Samknows too.

Hi Brian,

You should call their support if you think there’s something going on that’s impacting your connection.

They will detect if your connection is in use and doing more than (I think) 64kbit/s in the last 30s or something, and won’t run the tests.

They have some clever stuff to detect if your wifi is in use, without being connected to your network and without being your AP. Perhaps that’s playing up?

Pretty sure it’s publicly documented, check out the links in that original post and if not we can dig up some other stuff I’m sure.

Hi all,

Longtime listener; first time caller.

I signed up to SamKnows (partly out of curiosity and partly so I can have hard data about my connection that I pay for) at home.

Over the last week my connection has gone from slightly adequate with the occasional drop out to a slow connection with regular drop outs.

Netflix and YouTube are stuttering, video games drop connection, and websites hang at random times.

I can't help but think that the email shared by Dylan sheds some light on why that maybe.

This programme won't be terribly successful if everyone gets sick of having a terrible connection during peak hours and shuts the white box down.

Pretty frustrating.

Brian
