RE: Wanted: Asia bandwidth test files
Hi Micah, From: micah anderson [mailto:mi...@riseup.net] Thanks for the suggestion. Do you know what their bandwidth is? I can easily pull a .iso or similar from there to do some tests. There's some info at http://mirror.aarnet.edu.au/indexabout.html - it's connected at 10Gbps. Naturally what throughput you're able to get will depend on how you arrive on the AARNet network - there is unfortunately less bandwidth into the west of Australia from Asia is than there is into the east coast from the United States.

Wanted: Asia bandwidth test files
Hi, I'm sitting on what is advertised as a 100mbit/sec connection in Cambodia. I have been trying to verify that, because I do not believe it is valid. I did iperf tests from a number of network locations, and at one point I did get 71mbit/sec (most of the results were around 20-25mbit/sec or less). But I dont think 30 second iperf tests are particularly revealing when the bandwith rate might change drastically over the day. I considered doing a 3 day iperf test, but somehow this seems not how the tool was designed. Someone suggested I find test files from various Asian locations to download via wget. I found a bunch of 100mb test files for various providers in N. America and Europe on webhostingtalk, which were interesting, but I never got more than around 5mbit/sec with them. Does anyone have any machines in Japan, S. Korea, or other asian locations with good bandwidth. where they can host a 100mbit file so I can attempt to download it to test this? Other suggestions for reliable tests would also be welcome! Please, dont suggest some flash garbage :) thanks! micah --

Hi I think RING project NLNOG has potential to help your effort. https://ring.nlnog.net/ At least they have location in tokyo. And I talked with Seichi Kawamura who is leader of JANOG about method of quality　verification among the world wide. They are using host of Softlayer, amazon and OVH which could select the location.

Re: Wanted: Asia bandwidth test files
If you can, I suggest finding other well connected hosts and using IPERF in UDP mode for your testing. Separating TCP long-fat pipe and slow start issues from true packet delivery/loss rates at a given bitrate are beneficial. Use Linux as most iperf windows builds are based on cygwin and have issues at higher bitrates.

Hi Micah, You could try mirror.aarnet.edu.au, if Australia is sufficiently Asian for you...

Hi Micah Does anyone have any machines in Japan, S.
