OCN To Institute Daily Upload Limit

I received a postcard in the mail toady informing me that as of August 1, OCN, the internet provider operated by NTT Communications, has decided to impose a daily upload limit of 30GB per day.

The postcard stresses two things:

  • The limit is for some of its customers (一部のお客さまへの制限です。)
  • The limit is for P2P traffic only, meaning that it does not apply to browsing the internet and sending and receiving email(通常のホームページの閲覧、メール受信等の一般的なインターネットのご利用については、今回の制限対象となりませんのでご安心ください。)

The reason given for the limit is short and sweet: Some of its optical fiber and ADSL users regularly upload a lot more than 30GB a day.

If you happen to be one of these users, NTT will be notifying you shortly via email or snail mail. Users that continue to upload data in excess of the limit may have their internet access suspended or cut off altogether.

An explanation of the upload limit can be found here (in Japanese).

That's fair enough. No reason they should be using the capacity to that extent, causing (effectively) us to pay more....

OooooW Shit!! How will I sleep tonight!!
Thanks for that precious information!

I wanna know how to download/upload/whatever 30gb a day. It just took me over 24hrs to downlaod 7.5gb. If u know the answer please tell me. Until I know how I don't give a crap about their ruling/law/mandate/whatever.

30GB a day !! Holy cow I wish I had that problem. My crappy NZ ISP has a limit of 750MB UL/DL combined per day. After that I get slowed to dial-up speed. So I guess everyone in internet land is saying that I should change to a different ISP. The problem is that they are all that bad. Some of them will let you UL/DL more but then you have to pay an exorbitant charge per GB. Also Bittorrent traffic is throttled something chronic especially at peak times.

How I wish I was back in Japan with highspeed internet.

I got a similar card but it was 30MB a day. Maybe you misread yours.
The only people I know who download so much are foreigners. Most Japanese folk are too honorable to illegally DL such stuff and use P2P, maybe Winny for a few hit jpop singles and they sweat over doing that.

Well it says 30 GB here: http://www.ocn.ne.jp/info/rules/upload/index.html

1日あたり30ギガバイト(GB*3)

No, it's clearly GB. At least on my card. Maybe you're one of the "evil" P2P uploaders ;-)

As for Japanese not using P2P, I highly doubt it. They're just as busy downloading stuff as you are. I think there's a big demand for fans subtitling the latest episode of shows like "24" before they make their way to satellite TV in Japan.

Is your bittorrent traffic throttled by your ISP or is it because you haven't forwarded your ports?
I'm in Japan using NTT's fiber-optic connection and I was getting download speeds in bittorrent of about 5-30kb/s. Then I discovered port forwarding (basically opening the ports that bittorrent uses on your router). After doing so I'm now getting download speeds usually in the range of 300kb/s (and upload speeds of around 1Mb/s).
There's a good website that explains how to forward your ports at http://www.portforward.com/

By the way, anyone else using NTT: you can't use the above site to forward your ports. You have to use NTT's start up tool. If anyone would like to know how write a reply to this message and I'll detail how to do it.

Meh, no problem. Afer all, 640K ought to be enough for anybody, right? ;)

As we move towards Hi Def video 30GB is not a whole lot of data at all.

250GB Monthly caps are being instituted and companies are pushing towards metered usage fees.

Sounds like a great idea... So, how do you do it?

OK, well at first read it might seem a little involved but please try, it's not that hard.

First you need to know which ports you want opened. Check your bittorrent settings for the port you're using. It's suggested to make it a port over 10000. In this explanation I'll use my setting which is 40480.

Now you have to find your computer's IP address. Start the command prompt, type "ipconfig /all" and hit enter. Scroll up until you find "IP Address" under the "ethernet setting". It should be of the form "xxx.xxx.xx.xx" where the x's are numbers. Note the IP address down for later.

Next fire up your NTT internet connection tool. Mine's called スタートツール. There should be an option for settings (maybe a small button labelled 設定). Select the button, it will probably pop up a selection window, select CTU設定. This will pop up a browser window, you have to log in using your customer number and access password (you might have to find your original paperwork sent by NTT to find your customer number and password).

Assuming you've logged in you'll be presented with the CTU setings page. On the left side you'll see some buttons. Select the one labelled "詳細設定" ("detailed settings"). Now on the right side new information is presented.

Scroll the right side down until you reach "静的アドレス変換設定(ポート指定)". Under that it says "新しいルールの追加 : 優先順位" ("add new rule: priority") followed by an edit box. Assuming the main box under that is empty, just enter "1" (no quotes) in the edit box, and press the button to its right (追加 meaning "add").

A new page is shown with the info for the port range. Make sure the setting "プロトコル" is TCP, and then in the section "ポート番号" select the radio button "ポート番号を入力", and under that you have to fill in the first port number ("開始") and finish port number ("終了"). My port number is 40480 so I enter 40480 and 40490 for the start and finish port numbers (this lets me open 10 addresses). In the section "LAN側端末IPアドレス" enter your IP address that you made a note of above (the "xxx.xxx.xx.xx" one). Hit OK to return to the previous page.

Now scroll down to "静的アドレス変換設定(ポート変換)" and just like before enter "1" in the priority box and the 追加 button to add a new port forward. Fill this out much like the other one, leave "WAN側ポート番号" as "1", enter your IP address in "LAN側端末IPアドレス" and the port you want to forward in "LAN側ポート番号" (in my case 40480) and hit OK.

Now the easy part. On the left side of the page scroll to the bottom and just hit the big 戻る button. Now back to the previous page, on the left side select the "設定反映" button, and you're finished. You can then logout.

Hey, Thanks!

Instructions complete with the kanji squibbles and all. I'm not actually on my home computer now but I'll definitely try this.

Cheers!

As long as they focus on UPLOADing large amounts rather than downloading, I have no huge problem with it.

The typical high-end user who might even start watching Hi-def rental movies (those can be like 8GB per movie) with the new service from Tsutaya still doesn't have to worry if it's only limiting uploads.

If they want to really lock down the huge amount of traffic taken up by illegal downloads, either for legal(the lawyers), or just practical reasons(the cost) going after the major uploaders is the most efficient way to do it, AND you're definitely going after the hard-core pirates rather than the casual downloader. These really ARE the ones the record companies could claim are "ruining" their lame-ass, price-fixed, low-talent, cookie-cutter industry. ;)

After the outcry last April when the Japanese ISPs announced they were just going to start terminating accounts of illegal downloaders, they probably noticed they'd have to get rid of all their paying customers under the age of 35 and go bankrupt. Not a smart move.

Now they're kind of going after the drug suppliers rather than the users.

If all the ISPs decide to start charging per GB for large downloads, then either the ISPs will have download price plans as complicated as the mobile phone companies OR, they'll engage in illegal collusion and price-fixing. But that would NEVER happen in Japan. ;)

Hey I just took over my apartment from a friend. He had fiber and simply changed the name on the NTT account. Anyways, the NTT CTU was already set up by him I just changed my user name and password. I want to use torrents but I very sure that the CTU is not letting me open my ports. How did you manage to forward your ports

Hello Id like to have more info on port forwarding. Im using the NTT fiber optic service and not sure how to port forward since its in Japanese. Im pretty sure ive translated enough to turn the CTU firewall off but not anything else. Please email me if you have the info. Thanks

please help me how to open the 80 port since is a http and the ctu only has udp and tcp
