NTT Communications (NTT Com) will begin restricting network access by individual customers who upload more than 30 gigabytes (GB) of data per day. 
NTT Com said it will introduce the new bandwidth cap on August 1 “to help ensure stable, trouble-free access to the Internet for all customers.” The company noted that although it continues to expand its OCN optical network to accommodate increasing data traffic, a small number of individual users have been monopolizing substantial network resources by uploading massive amounts of data, which can slow the speed of the network and lower communication quality for other users.
NTT Com will begin to implement the policy by first notifying any individual that exceeds the 30 GB daily limit. The user will be asked to observe the limit. If they do not, OCN will suspend their access to the network and possibly terminate their service contract.
Downlink traffic, such as browsing, receiving e-mails and data downloading, will not be subject to the 30GB limitation.http://www.ntt.com
- In May, NTT reported that the number of FLET’S Hikari optical access subscriptions reached 8.78 million as of March 31, 2008, up from 3.2 million a year earlier. Meanwhile, the number of ADSL subscribers fell to 4.6 million from 5.3 million a year earlier. Likewise, the number of conventional telephone lines fell to 39.2 million from 43.3 million last year.
