Forty years after it was invented, the Internet is straining under the weight of cyber attacks, multimedia content and new mobile applications. In response, U.S. computer scientists are re-thinking every aspect of the Internet's architecture, from IP addresses to routing tables (see main story: 2020 Vision: Why you won't recognize the 'Net in 10 years) to overall Internet security. There are many views about how to fix the Internet's architecture, but there's widespread agreement about many aspects of the future Internet. Here's our list of 11 surefire bets for what the Internet will look like in a decade.
1. More people will use the Internet.
2. The Internet will be more geographically dispersed.
3. The Internet will be a network of things, not computers.
4. The Internet will carry exabytes — perhaps zettabytes — of content.
5. The Internet will be wireless.
6. More services will be in the cloud.
7. The Internet will be greener.
8. Network management will be more automated.
9. The Internet won't rely on always-on connectivity.
