Some researchers who study the architecture of global networks believe that peering is fundamentally transforming the Internet’s configuration, with far-reaching ramifications for the Web’s stability and security. Arbor Networks’ Internet Observatory Report found that the bulk of Internet traffic by volume flows directly between major content providers such as Google and consumer networks such as Comcast, while 30 percent of all traffic is produced and consumed by 30 “hyper giant” portals such as Microsoft, Facebook, and YouTube. The edge of the Internet is getting thicker due to the emergence of massive peering fabrics, which may be fortifying the network’s resilience. “The rise of these highly connected data centers around the world is changing our model of the Internet,” says Cornell University researcher Jon M. Kleinberg. However, he notes that the advent of giant distributed data centers as part of the development of cloud computing services is enlarging the dark Internet, compounding scientists’ difficulty in constructing a complete model. “The Internet as we know it is pretty much vanishing, in the sense that much of the traffic is being routed through lots of new layers and applications, much of it wireless,” says Albert-Laszlo Barabasi, director of Northeastern University’s Center for Network Science.

Information technology (IT) needs to be taught a different way in schools if the industry is to deepen its talent pool, experts in the United Kingdom said during a recent e-Skills event. British Computer Society CEO David Clarke says that although young people are more connected than anyone else in society, they view IT as boring in school because it is taught in a secretarial manner. Students are trained to copy the teachers’ instructions, but they prefer to learn in groups and work on practical tasks, Clarke says. The Confederation of British Industry’s (CBI’s) Lizzie Holman says the same problem exists at the degree level. CBI statistics show that 64 percent of science, high technology, and IT employers believe students do not receive relevant content for the workforce. Europe faces a potential shortage of 384,000 information and communication technology practitioners by 2015, according to the European Commission.
