The internet may be fragile

A hacker told Congress he could paralyze the entire Internet in half an hour. The hacker named Peiter Zatko, a member of the "hacker think-tank" L0pht, is now working on a new job for the Pentagon's senior research programme. Zatko says many of the internet's vulnerabilities are still valid today. But he still needs a few hours to get the internet all paralyzed, partly because of the growing number of Internet carriers (carriers).

Whether you are e-mailing or browsing the web. You read and transmit information from one data carrier to another, and transmission routes are sometimes very long. The problem is that each carrier transmits data only according to other carrier signals around the route, not the entire route. Therefore, the signal may be pointing in the wrong direction, causing the information to be lost in transit. This is the Internet traffic is hijacked the biggest reason, data carrier in the Internet "black hole" lost direction.

In 1997, millions of U.S. residents were unable to connect to the Internet within one hours, and the hijacking was due to an ISP router Setup error. Routing errors often cause network connections in other parts of the world to be interrupted. The accident occurred in 2001, 2004, 2005, 2006, 2008 and 2009. Last month a Chinese ISP caused dozens of websites, including dell.com and CNN.com, to interrupt access for 20 minutes. The Internet routing system has not been reformed for more than 10 years, although some progress has been made, but there is a lack of industry-wide impetus.
