NTT Com's Japan-U.S. backbone bandwidth reaches 600 Gbps
Technology ( 16 )
TOKYO —
NTT Communications Corp said Monday that it has expanded the data-transmission capacity of its Global IP Network between Japan
and the United States to an industry-leading 600 gigabits per second (Gbps). The new capacity, equivalent to approximately 35,000 channels of digital terrestrial television or more than five centuries’ worth of content in a daily newspaper, further enhances the company’s leadership in Tier-1 trans-Pacific IP connectivity.
NTT Com’s global IP backbones are connected to fixed and mobile telecom companies, Internet service providers (ISPs), data center operators and content providers, enabling customers to meet their growing needs for Internet capacity between Japan and the United States.
Although a part of the cable was damaged following the March 2011 earthquake, it was quickly repaired with minimum disconnection. This was thanks to the fully redundant cable structure and collaborative efforts with multiple carriers and cable companies, based on an established cooperative relationship. The network, which is IPv4 and IPv6 dual-stack, is one of NTT Com’s core IPv6 networks.
Demand for high-capacity bandwidth has been growing rapidly in recent years, reflected in the seven-fold increase in NTT Com’s Japan-U.S. bandwidth between 2005 and 2010. This latest jump - from 500 Gbps to 600 Gbps in just four months - aims to cater to even stronger demand being generated in today’s cloud-computing, micro-blogging, social network and online media-intensive environment.

Please know what you are writing about, this does not make any sense

Not sure whether it is just a coincidence, but a speed test I just did on my iPhone showed this, compared to previous tests:
12/20/11 DOWNLOAD 6.36 Mbps UPLOAD 0.70 Mbps (at 1 pm)
11/18/11 DOWNLOAD 4.07 Mbps UPLOAD 0.63 Mbps (at 11 pm)
Three other tests I did on 11/18 showed similar results.
This suggests a quite large speed boost, actually -- up 57%.
I'll try it again tonight and see if it has something to do with nighttime traffic.
Or it might be that I now have an iPhone 4S.

I tested my iPhone 3GS, and it was slightly slower than the 4S, but not a great deal.
But looking at the results of speed tests I've done on it the last 2 years, there is no question the mid-day download speeds are now much faster -- more than double what I was seeing in 2010, when 2.8 Mbps (and lower) was common.

What a load of nonsense for the customer of NTT and quite meaningless in the real world. Some months back I updated my fiber optic connection from 100 Mbps to 200 Mbps. I was going to change to 1000 Mbps but at the last moment I changed my mind because it would cost twice as much and I wasn't sure I would even get that speed.
The update to 200 Mbps was same price as 100 Mbps except for some small changing fee. It also meant I got one router instead of my previous three and wireless came with it, which is nice. I also changed to HikariTV from SkyPrefect since it was time to have HD. There's no land phone, its IP.
The speed of everything works fine. Good HikariTV even when I'm also video editing on the computer. No problem with the IP phone, even for international calls and no problem with computer download/uploads. I can usually download a full DVD in less than 20 minutes.
But if you want to know actual speeds, well as always, NTT just states "the figures are the assumed best and not actual figures". From Kobe -->Osaka -->Tokyo best speed is about 100 Mbps, sometimes like in the middle of the night, a bit more.
Work wise and mostly for my family most of the time I'm connected to America, then speed is anything from 50 Mbps to 100 Mbps. The time difference helps out a lot but means I'm usually up at least half the night and sometimes to dawn.
Anyway, like I said, all meaningless for the user.

Wow, I still only ever get about 5-6Mbps down and 1-2 up on a LAN cable right out of the router. It hasn't changed since 2004 even though I've moved progressively from DSL to fiber optic (now advertised as 100Mbps), moved from place to place in Tokyo, and now reside in Kurashiki.

I have JCom fiber. Wireless high speed Buffalo. Torrents sometimes are so slow.
What is a good test for a Mac?

waiting to get this speed from our wifi

Wondering how many of the currently used computers/devices are setup/configured for those higher speeds? Takes more than just a high-speed card, etc to take advantage of the additional data-rates.
You can take an old Mini onto the Autobahn but it still won't exceed the speed of the Mini, neither will it speed up if they add another 4 lanes.

Speed Test here: (Mac) or.... http://www.speedtest.net/
I use JCom 160 mbs cable for the net.
My speed test showed: 40.25 Mbps DL 6.20 Mbps UL
One never gets the full speed as advertised.
Though I feel it's pretty fast.

My WIFI must be the bottleneck. And definitely slower in the evening, at 4.7 Mbps DL. Suspect it's all allocated, anyway. But the bigger the highway, the more they have to allocate.

22 down and 6 up
each check varies

Will vary as each test has to go through various servers and their load changes constantly. Add in to that peak-hours for usage and many other factors, like the ping will take a different route.

Find your country here. Lots of good ones for Japan

On NTT Fiber 74.72Mbps down and 10.11Mps up.

In general, these trunk line upgrades are not felt by the individual users. Upgrades are done in order to provide reliable access to everyone, including private companies and government facilities that rely on internet connectivity.
When the providers do not upgrade, that is the time we, the users would feel the slowing down of the internet access.
