CISCO SYSTEMS WAS OUT LAST WEEK WITH ITS ANNUAL “VISUAL NETworking
Index Forecast,” or “VNI,” which aims to put some numbers
on the mind-bending enormity of Internet traffic.
The full report goes off in all kinds of interesting directions.
This week’s translation walks through some of the language of
what’s quickly becoming the even bigger Very Big Numbers of
WHAT’S AN EXABYTE?
Let’s start with the “Exabyte,” abbreviated “EB,” because that’s
where we’re headed between now and 2014. An Exabyte is
one quintillion bytes. It’s a one, with 18 zeros behind it.
According to the VNI Forecast, Internet traffic around the
globe will reach nearly 64 exabytes per month in 2014. That’s
equivalent to 11.8 billion DVDs, 15.8 trillion MP3 files, or 295
quadrillion text messages.
In the hierarchy of numbers, the Exabyte comes after the
Petabyte, but before the Zettabyte. (That’s right. Zettabyte.
Although “Zappabyte” seems just as effective.)
So: A Gigabyte (GB) is 1,000 Megabytes (MB); a Terabyte
(TB) is 1,000 Gigabytes; a Petabyte (PB) is 1,000 Gigabytes; an
Exabyte (EB) is 1,000 Petabytes, and a Zettabyte (ZB) is 1,000
And yes, there’s one more after that — the “Yottabyte (YB).”
You guessed it: 1,000 Zettabytes. (Which gives new oomph to
“yotta, yotta, yotta.”)
MORE SCREENS, MORE ‘AMBIENT’ VIDEO
What’s spawning all this data? It’s the bits of video, of course.
Consider recent headlines: Sony’s new OLED screen is thin
enough to wrap around a pencil. Apple sells 2 million iPads in
two months. SlingPlayer gets ready to launch on the mobile
All kinds of screens, all thirsty for video. How much screen
space? Wrap your head around 12 billion square feet of consumer
multiscreen surface area by 2014. That’s what the study
And let’s not forget what the VNI Forecast characterizes as
“ambient video,” which was a new one on me. “Ambient video”
is streaming video that persists, but mostly in the background:
The home-security camera, the nanny-cam, the off!-off!-dogon-
the-couch-cam. That traffic is expected to go berserk in the
next few years, too.
Another strong implication in this year’s VNI Forecast: transference.
What we have on one screen, we’ll want on others
— whether those screens are fixed or mobile; whether that
video is entertainment or a face-to-face conversation.
On a working level, everything within the VNI Forecast validates
that it’s a fast and feisty time to be a video service provider.
On a human-being level, I’m with blogger Seth Godin, who
said this in his Memorial Day post: “When does the mind lose the
ability to keep up? Then what happens? Is it already happening?”
And, as a technology observer, I also wonder: Where do we
go after Yotta?
