Japan to punish p2p users
jamie | June 29, 2008…And this time it’s serious - by which I mean it may actually affect me!
OCN/NTT Communications (read, my ISP) have announced a new daily *upstream* limit of 30gb in order to curb the heavy usage of a few p2p users - like myself, I guess. There are no current plans for a download limit, however they will send warnings to users found to be sharing files via the popular Japanese p2p application Winny .
Now 30gb may not seem like much to you, but when you have genuinely fast internet like myself…

30 gb uploaded is nothing, as you can see. Curious that my upload is actually faster than my download speed, though. According to speedtest.net, my internet is faster than 99% of everyone else who has taken the test, and is well above the Japanese national average of about 4 mb/sec.
Assuming my torrent seeds (for legal material, of course) were all running at maximum throughput, Azureus would rape 30gb in about 16 minutes. Yes, 16 fucking minutes. This could be a problem 128 minutes. Still a problem, despite my dodgy calculations.
For anyone else worried or affected by this fascistic limit, I did some calculations to figure out what the global upload speed limit should be set to so as to ensure the 30gb limit is never exceeded:
- Assuming you will be using your net for other things too like online gaming and such, let’s say a daily limit of 24 gb. That gives us a nice round figure of 1gb/hour to work with.
- 1,000 mb / 60 minutes works out at around 16.666 mb / minute.
- 16,666 kb / 60 seconds gives a final speed of 277 kb/s maximum. All decent torrent clients like Azureus and uTorrent allow you to set global speed limits.
So there you have it - set your upload limit to 270 kb and you should be safe. You might also want to turn on forced encryption and disallow torrent connections to unencrypted peers. This will make perfectly sure that your ISP has no idea what you’re actually transferring, even with deep packet inspection. I also highly suggest running PeerGuardian, which updates daily with lists of banned IPs, like anti p2p companies injecting torrents with corrupted data to fuck up your downloads, as well as various evil and / or governmental organizations that will harvest your IP address if they find you sharing and then proceed to sue your ass. You have been warned.
How fast is your internet? Does your ISP inflict insufferable limits? Answers in the comments, please!











Heh. You got it easy. Here: 1mb down, 512kbps up,
Monzo | June 30, 2008Heh. You got it easy. Here: 1mb down, 512kbps up, 30Gb MONTHLY limit (up+down combined, all protocols).
Fortunately for you, seems you got bits and bytes messed
Kuukunen | June 30, 2008Fortunately for you, seems you got bits and bytes messed up, so you’re not quite as fucked up. The limit seems to be gigaBYTES, but speedtest counts stuff in BITS. (Notice lower case b in speedtest.net) For some reason internet connection is usually counted in bits, probably because it makes the number much bigger. So just multiply your stuff by 8: It takes 128 minutes to reach the limit at full speed. Azureus, however, probably uses kiloBYTES when you set the limit, so 277 kB/s should be ok. Although 24 GB is playing it a bit safe. Your non-torrent stuff will probably take like 10 MB, tops.
Of course there’s still the minor thing of: Do they use 1000 bytes per kilobyte or 1024? Because if it’s 1024, the upload limit for 24GB would be 291 kB/s, not that it matters too much.
Limits like that can be a bitch, but I was on 20mbps connection with 14 GB WEEKLY upload limit, but of course when people take stuff like that for granted, it hurts when it changes.
I thought 16 minutes sounded a bit low. Wow, that
jamie | June 30, 2008I thought 16 minutes sounded a bit low.
Wow, that is embarrassing, especially since I majored in computer science…
Well, I'm using "unlimited" connection, so there's no hard bandwidth
antsheaven | June 30, 2008Well, I’m using “unlimited” connection, so there’s no hard bandwidth usage limit. But They capped my upload speed at 128 kbps. Yes, 128 goddamn kbps. Which nicely translate to 16 kByte per second
And I have 1500kbps download speed, so i need to seed my (perfectly legal) torrent for at least a week, jut not to feel guilty.
And, yeah, there are 8 bits in 1 byte, you forgot to put that up in the equation.
Holy shit. You guys totally need to move to Japan...
jamie | June 30, 2008Holy shit. You guys totally need to move to Japan…
here @ Jakarta, I am using 'unlimited' up to 384kbps
idarmadi | July 3, 2008here @ Jakarta, I am using ‘unlimited’ up to 384kbps up, up to 128kbps down for appx $10/month. It’s pretty ’slow’ and crappy, but it’s better than before.
Jamie, how much does it cost for your connection?
Mine is about 5,000 yen a month ~ $50 dollars.
jamie | July 3, 2008Mine is about 5,000 yen a month ~ $50 dollars.
UPDATE: I got sent a little warning card about the new limit today. Apparently, it starts on August 1st, by which time I will have moved, so for the next month it’ll be a free for all on my torrents methinks!
