Cisco Internet Predictions 2015

Each year Cisco gets its best and brightest minds together to make some predictions. The following are for the 2015 predictions.

Annual global IP (internet) traffic will surpass the zettabyte (1000 exabytes) threshold in 2016, and the two zettabyte threshold in 2019.

Global IP traffic has increased more than fivefold in the past 5 years, and will increase nearly threefold over the next 5 years. Overall, IP traffic will grow at a compound annual growth rate (CAGR) of 23 percent to 2019.

Content delivery networks will carry 62% of Internet traffic by 2019, up from 39 percent in 2014.

Over half of all IP traffic will originate with non-PC devices by 2019, up from 40 percent in 2014.

Personal computer-originated traffic will grow at a CAGR of just 9 percent, while TVs, tablets, smartphones, and machine-to-machine (M2M) modules will have traffic growth rates of 17 percent, 65 percent, 62 percent, and 71 percent, respectively.

By 2019, Wi-Fi and mobile devices will account for 66 percent of IP traffic and wired devices will account for just 33 percent.

Global Internet traffic in 2019 will be equivalent to 64 times the volume of the entire global Internet in 2005.

The number of devices connected to IP networks will be three times the global population in 2019.

By 2019, global fixed broadband speeds will reach 43 Mbps, up from 20 Mbps in 2014.

It would take an individual over 5 million years to watch the amount of video that will cross global IP networks each month in 2019. Every second, nearly a million minutes of video content will cross the network by 2019.

How Big is the Internet

Some experts say that the Internet is growing by an exabyte of data every day. To put that in perspective, an exabyte equals 250 million DVDs.

After an exabyte comes a zettabyte, which equals 1,000 exabytes. In 2011, no single data center could hold a zettabyte of information.

By 2016, Cisco predicts that data centers will be sending more 1.3 zettabytes across the Internet every year. That's the equivalent of sending all movies ever made across the Internet every 3 minutes.

The National Security Agency is building a $2 billion data center in Utah that will be the world's first to store a store a yottabyte of data. That's 1,000 zettabytes or 1 million exabytes (or 1 million billion gigabytes).

Over half of Americans have watched TV streamed from the Internet.

Exabytes

From bites to bytes - Last year, manufacturers shipped 5.1 exabytes of storage devices. An exabyte is a quintillion bytes, or a thousand trillion. Below are some more interesting tidbits about exabytes and the internet.

* In 2004, global monthly Internet traffic passed 1 exabyte for the first time and six years later, it is estimated at 21 exabytes per month, or 252 exabytes per year.

* Mobile data traffic is growing faster than non-mobile traffic, has tripled each year for the past three years, and is projected to rise another 26-fold to about 75 exabytes per year by 2015. (The top 1 percent of mobile data subscribers generate over 20 percent of mobile data traffic,)  

* Non-mobile internet traffic has averaged 151% growth each year since 1997.

* By 2013, annual global internet traffic will reach two-thirds of a zettabyte or 667 exabytes.

* Global mobile data traffic will reach over two exabytes per month by 2013.

*  It is estimated that there was 988 exabytes of data created last year, 2010. That is over 18 million times the amount of information contained in all the books ever written.

Zettabyte

Humankind will generate over one sextillion bytes of digital information this year, surging into a zettabyte. In 2010, 1.2 zettabytes of digital information will be created, according to a new Digital Universe study from IDC, sponsored by IT firm EMC Corporation.

A zettabyte is 1,000,000,000,000,000,000,000 bytes (that's 21 zeroes for those counting). Think of a zettabyte like watching an hour long tv show continuously for 125 years.
