Here are 10 surefire bets for what the Internet will look like in a decade.
1. More people will use the Internet.
Today's Internet has 1.7 billion users. The National Science Foundation predicts that the Internet will have nearly 5 billion users by 2020.
2. The Internet will be more geographically dispersed.
Most of the Internet's growth over the next 10 years will come from developing countries. The Internet in 2020 will not only reach more remote locations around the globe but also will support more languages and non-ASCII scripts.
3. The Internet will be a network of things, not computers.
As more critical infrastructure gets hooked up to the Internet, the Internet is expected to become a network of devices rather than a network of computers. The NSF is expecting billions of sensors on buildings and bridges to be connected to the Internet for such uses as electricity and security monitoring.
4. The Internet will carry exabytes -- perhaps zettabytes -- of content.
Global Internet traffic will grow to 44 exabytes per month by 2012 -- more than double what it is today.
5. The Internet will be wireless.
The number of mobile broadband subscribers is exploding, hitting 257 million in the second quarter of 2009. But by 2014, 2.5 billion people worldwide will subscribe to mobile broadband.
6. More services will be in the cloud.
Experts agree that more computing services will be available in the cloud. Cloud computing will generate more than $45.5 billion in revenue by 2015.
7. The Internet will be greener.
The Internet's so-called Energy Intensity is growing at a slower rate than data traffic volumes as networking technologies become more energy efficient. The trend towards greening the Internet will accelerate as energy prices rise.
8. Network management will be more automated.
The National Science Foundation is seeking ambitious research into new network management tools. Among the ideas under consideration are automated ways to reboot systems, self-diagnosing protocols, finer grained data collection and better event tracking.
9. The Internet won't rely on always-on connectivity.
With more users in remote locations and more users depending on wireless communications, the Internet's underlying architecture can no longer presume that users have always-on connections.
10. The Internet will attract more hackers.
In 2020, more hackers will be attacking the Internet because more critical infrastructure like the electric grid will be online. The Internet is already under siege, and attacks will only get more targeted, more sophisticated and more widespread in the future.
